                  1.   Definitions

                              A.

                              Product Types:
                              1.   Computer: A device which performs logical operations and processes data. For the purposes of this specification, computers include both stationary and portable units, including Desktop Computers, Integrated Desktop Computers, Notebook Computers, Small-Scale Servers, Thin Clients, and Workstations. Although computers are capable of using input devices and displays, such devices are not required to be included with the computer upon shipment. Computers are composed of, at a minimum:

                                          a)

                                          A central processing unit (CPU) to perform operations. If no CPU is present, then the device must function as a client gateway to a server which acts as a computational CPU;

                                          b)

                                          User input devices such as a keyboard, mouse, or touchpad; and

                                          c)

                                          An Integrated Display screen and/or the ability to support an external display screen to output information.

                                    2.   Desktop Computer: A computer whose main unit is designed to be located in a permanent location, often on a desk or on the floor. Desktop computers are not designed for portability and are designed for use with an external display, keyboard, and mouse. Desktop computers are intended for a broad range of home and office applications, including point of sale applications.
                              a)   Integrated Desktop Computer: A Desktop Computer in which the computing hardware and display are integrated into a single housing, and which is connected to ac mains power through a single cable. Integrated Desktop Computers come in one of two possible forms: (1) a system where the display and computer are physically combined into a single unit; or (2) a system packaged as a single system where the display is separate but is connected to the main chassis by a dc power cord and both the computer and display are powered from a single power supply. As a subset of Desktop Computers, Integrated Desktop Computers are typically designed to provide similar functionality as Desktop systems.
                              3.   Notebook Computer: A computer designed specifically for portability and to be operated for extended periods of time both with and without a direct connection to an ac mains power source. Notebook Computers include an Integrated Display, a non-detachable, mechanical keyboard (using physical, moveable keys), and pointing device.

                                 Note: Notebook computers are typically designed to provide similar functionality to Desktops, including operation of software similar in functionality as that used in Desktops. For purposes of this specification, Notebook Computers include models with touch-sensitive screens.
                              a)   Mobile Thin Client: A computer meeting the definition of a Thin Client, designed specifically for portability, and also meeting the definition of a Notebook Computer. These products are considered to be Notebook Computers for the purposes of this specification.

                                          Includes an internal battery, but is primarily powered by connection to the ac mains.

                                    6.   E-Reader: A device designed for display and consumption of static images. The display is characterized by a low refresh rate and a display made of bistable materials where no energy is needed to maintain a visible image, only to alter the image.
                              7.   Small-scale Server: A computer that typically uses desktop components in a desktop form factor, but is designed primarily to be a storage host for other computers. Small-scale Servers are designed to perform functions such as providing network infrastructure services (e.g., archiving) and hosting data/media. These products are not designed to process information for other systems or run web servers as a primary function. A Small-scale Server has the following characteristics:

                                          a)

                                          Designed in a pedestal, tower, or other form factor similar to those of desktop computers such that all data processing, storage, and network interfacing is contained within one box/product;

                                          b)

                                          Designed to operate 24 hours/day, 7 days/week, with minimal unscheduled downtime (on the order of hours/year);

                                          c)

                                          Capable of operating in a simultaneous multi-user environment serving several users through networked client units; and

                                          d)

                                          Designed for an industry accepted operating system for home or low-end server applications (e.g., Windows Home Server, Mac OS X Server, Linux, UNIX, Solaris).

                                    8.   Thin Client: An independently-powered computer that relies on a connection to remote computing resources (e.g., computer server, remote workstation) to obtain primary functionality. Main computing functions (e.g., program execution, data storage, interaction with other internet resources) are provided by the remote computing resources. Thin Clients covered by this specification are (1) limited to devices with no rotational storage media integral to the computer and (2) designed for use in a permanent location (e.g. on a desk) and not for portability.
                              a)   Integrated Thin Client: A Thin Client in which computing hardware and display are connected to ac mains power through a single cable. Integrated Thin Client computers come in one of two possible forms: (1) a system where the display and computer are physically combined into a single unit; or (2) a system packaged as a single system where the display is separate but is connected to the main chassis by a dc power cord and both the computer and display are powered from a single power supply. As a subset of Thin Clients, Integrated Thin Clients are typically designed to provide similar functionality as Thin Client systems.
                              b)   Ultra-thin Client: A computer with lesser local resources than a standard Thin Client that sends raw mouse and keyboard input to a remote computing resource and receives back raw video from the remote computing resource. Ultra-thin clients cannot interface with multiple devices simultaneously nor run windowed remote applications due to the lack of a user-discernible client operating system on the device (i.e., beneath firmware, user inaccessible).
                              9.   Workstation: A high-performance, single-user computer typically used for graphics, CAD, software development, financial and scientific applications among other compute intensive tasks. Workstations covered by this specification (a) are marketed as a workstation; (b) provide mean time between failures (MTBF) of at least 15 000 hours (based on either Bellcore TR-NWT-000332, issue 6, 12/97 or field collected data); and (c) support error-correcting code (ECC) and/or buffered memory. In addition, a workstation meets three or more of the following criteria:

                                          a)

                                          Provide supplemental power support for high-end graphics (e.g., PCI-E 6-pin 12V supplemental power feed);

                                          b)

                                          Wired for greater than x4 PCI-E on the motherboard in addition to the graphics slot(s) and/or PCI-X support;

                                          c)

                                          Do not provide support for Uniform Memory Access (UMA) graphics;

                                          d)

                                          Provide 5 or more PCI, PCI-E, or PCI-X slots;

                                          e)

                                          Provide multi-processor support for 2 or more processors (shall support physically separate processor packages/sockets, i.e., requirement cannot be met with support for a single multi-core processor); and/or

                                          f)

                                          Qualification by 2 or more Independent Software Vendor (ISV) product certifications; these certifications can be in process, but shall be completed within 3 months of qualification.

                              B.

                              Product Category: A second-order classification or sub-type within a product type that is based on product features and installed components. Product categories are used in this specification to determine qualification and test requirements.

                              C.

                              Computer Components:
                              1.   Graphics Processing Unit (GPU): An integrated circuit, separate from the CPU, designed to accelerate the rendering of either 2D and/or 3D content to displays. A GPU may be mated with a CPU, on the system board of the computer or elsewhere to offload display capabilities from the CPU.
                              2.   Discrete Graphics (dGfx): A graphics processor (GPU) with a local memory controller interface and local graphics-specific memory.
                              3.   Integrated Graphics (iGfx): A graphics solution that does not contain Discrete Graphics.
                              4.   Display: A commercially-available product with a display screen and associated electronics, often encased in a single housing, that as its primary function displays visual information from (1) a computer, workstation or server via one or more inputs (e.g., VGA, DVI, HDMI, DisplayPort, IEEE 1394, USB), (2) external storage (e.g., USB flash drive, memory card), or (3) a network connection.
                              a)   Enhanced-performance Integrated Display: An integrated Computer Display that has all of the following features and functionalities:

                                          (1)

                                          A native resolution greater than or equal to 2,3 megapixels (MP); and

                                          (3)

                                          A colour gamut of at least sRGB as defined by European Standard EN 61966-2-1 (identical with IEC 61966-2-1). Shifts in colour space are allowable as long as 99 % or more of defined sRGB colours are supported.

                                    5.   External Power Supply (EPS): Also referred to as External Power Adapter. An external power supply circuit that is used to convert household electric current into dc current or lower-voltage ac current to operate a consumer product.
                              6.   Internal Power Supply (IPS): A component internal to the computer casing and designed to convert ac voltage from the mains to dc voltage(s) for the purpose of powering the computer components. For the purposes of this specification, an internal power supply shall be contained within the computer casing but be separate from the main computer board. The power supply shall connect to the mains through a single cable with no intermediate circuitry between the power supply and the mains power. In addition, all power connections from the power supply to the computer components, with the exception of a DC connection to a display in an Integrated Desktop Computer, shall be internal to the computer casing (i.e., no external cables running from the power supply to the computer or individual components). Internal dc-to-dc converters used to convert a single dc voltage from an external power supply into multiple voltages for use by the computer are not considered internal power supplies.

                              D.

                              Operational Modes:
                              1.   Active State: The power state in which the computer is carrying out useful work in response to a) prior or concurrent user input or b) prior or concurrent instruction over the network. Active State includes active processing, seeking data from storage, memory, or cache, including Idle State time while awaiting further user input and before entering low power modes.
                              2.   Idle State: The power state in which the operating system and other software have completed loading, a user profile has been created, activity is limited to those basic applications that the system starts by default, and the computer is not in Sleep Mode. Idle State is composed of two sub-states: Short Idle and Long Idle.
                              a)   Long Idle: The mode where the Computer has reached an Idle condition (i.e., 15 minutes after OS boot or after completing an active workload or after resuming from Sleep Mode) and the main Computer Display has entered a low-power state where screen contents cannot be observed (i.e., backlight has been turned off) but remains in the working mode (ACPI G0/S0). If power management features are enabled as-shipped in the scenario described in this definition, such features shall engage prior to evaluation of Long Idle (e.g., display is in a low power state, HDD may have spun-down), but the Computer is prevented from entering Sleep Mode. PLONG_IDLE represents the average power measured when in the Long Idle Mode.
                              b)   Short Idle: The mode where the Computer has reached an Idle condition (i.e., 5 minutes after OS boot or after completing an active workload or after resuming from Sleep Mode), the screen is on, and Long Idle power management features have not engaged (e.g. HDD is spinning and the Computer is prevented from entering sleep mode). PSHORT_IDLE represents the average power measured when in the Short Idle mode.
                              3.   Off Mode: The lowest power mode which cannot be switched off (influenced) by the user and that may persist for an indefinite time when the appliance is connected to the main electricity supply and used in accordance with the manufacturer's instructions. For systems where ACPI standards are applicable, Off Mode correlates to ACPI System Level S5 state.
                              4.   Sleep Mode: A low power mode that the computer enters automatically after a period of inactivity or by manual selection. A computer with Sleep capability can quickly “wake” in response to network connections or user interface devices with a latency of less than or equal to 5 seconds from initiation of wake event to system becoming fully usable including rendering of display. For systems where ACPI standards are applicable, Sleep Mode most commonly correlates to ACPI System Level S3 (suspend to RAM) state.

                              E.

                              Networking and Additional Capabilities:
                              1.   Additional Internal Storage: Any and all internal hard disk drives (HDD) or solid state drives (SSD) shipping with a computer beyond the first. This definition does not include external drives.
                              2.   Energy Efficient Ethernet (EEE): A technology which enables reduced power consumption of Ethernet interfaces during times of low data throughput. Specified by IEEE 802.3az.
                              3.   Full Network Connectivity: The ability of the computer to maintain network presence while in Sleep Mode or an alternative low power mode (LPM) with power less than or equal to 10 watts and intelligently wake when further processing is required (including occasional processing required to maintain network presence). Presence of the computer, its network services and applications, is maintained even though the computer is in a LPM. From the vantage point of the network, a computer with full network connectivity that is in LPM is functionally equivalent to an idle computer with respect to common applications and usage models. Full network connectivity in LPM is not limited to a specific set of protocols but can cover applications installed after initial installation. Also referred to as “network proxy” functionality and as described in the Ecma-393 standard.
                              a)   Network Proxy — Base Capability: To maintain addresses and presence on the network while in LPM, the system handles IPv4 ARP and IPv6 NS/ND.
                              b)   Network Proxy — Full Capability: While in LPM, the system supports Base Capability, Remote Wake, and Service Discovery/Name Services.
                              c)   Network Proxy — Remote Wake: While in LPM, the system is capable of remotely waking upon request from outside the local network. Includes Base Capability.
                              d)   Network Proxy — Service Discovery/Name Services: While in LPM, the system allows for advertising host services and network name. Includes Base Capability.
                              4.   Network Interface: The components (hardware and software) whose primary function is to make the computer capable of communicating over one or more network technologies. Examples of Network Interfaces are IEEE 802.3 (Ethernet) and IEEE 802.11 (Wi-Fi).
                              5.   Wake Event: A user, scheduled, or external event or stimulus that causes the computer to transition from Sleep Mode or Off Mode to an active state of operation. Examples of wake events include, but are not limited to: movement of the mouse, keyboard activity, controller input, real-time clock event, or a button press on the chassis, and in the case of external events, stimulus conveyed via a remote control, network, modem, etc.
                              6.   Wake On LAN (WOL): Functionality which allows a computer to transition from Sleep Mode or Off Mode to an Active State of operation when directed by a network Wake Event via Ethernet.
                              7.   Switchable Graphics: Functionality that allows Discrete Graphics to be disabled when not required in favour of Integrated Graphics.

                                 Note: This functionality allows lower power and lower capability integrated GPUs to render the display while on battery or when the output graphics are not overly complex while then allowing the more power consumptive but more capable discrete GPU to provide rendering capability when the user requires it.

                              Marketing and Shipment Channels:
                              1.   Enterprise Channels: Sales channels typically used by large and medium-sized business, government, educational, or other organizations to purchase computers for use in managed client/server environments.
                              2.   Model Name: A marketing name that includes reference to the computer model number, product description, or other branding references.
                              3.   Model Number: A unique marketing name or identification reference that applies to a specific hardware and software configuration (e.g., operating system, processor type, memory, GPU), and is either pre-defined or selected by a customer.

                              G.

                        3.5.   Requirements for Desktop, Integrated Desktop, and Notebook Computers

                              3.5.1.

                              Calculated Typical Energy Consumption (ETEC) for Desktop, Integrated Desktop, and Notebook Computers per Equation 1 shall be less than or equal to the maximum TEC requirement (ETEC_MAX) per Equation 2, subject to the following requirements:

                                          (i)

                                          The Additional Internal Storage adder allowance (TECSTORAGE) shall be applied if there are more than one internal storage devices present in the product, in which case it shall only be applied once.

                                          (ii)

                                          The Integrated Display adder allowance (TECINT_DISPLAY) applies only for Integrated Desktops and Notebooks and may be applied for each display. For Enhanced-performance Integrated Displays, the adder is calculated as presented in Table 7 and Equation 3.

                                          (iii)

                                          For a product to qualify for the Full Network Connectivity mode weightings, the following criteria shall be satisfied:

                                                      —

                                                      Products shall meet a non-proprietary Full Network Connectivity standard such as ECMA 393 or another standard that has been approved by EPA or the European Commission as meeting the goals of ENERGY STAR. Such approval must be in place prior to submittal of product data for qualification.

                                                                  —

                                                                  Products shall have the applied level of functionality enabled and configured by default upon shipment. If Full Network Connectivity features are not enabled by default, the system shall be tested and reported with Conventional TEC weightings.

                                                                  —

                                                                  Products shall be capable of Sleep Mode or alternative low power modes with power less than or equal to 10 watts.

                                                      —

                                                         Note: Full Network Connectivity is a manufacturer-reported parameter. On Mac computers, “Wake for network access” enabled within the Energy Saver/Power Adapter Preferences signifies Base Capability or better. On Windows computers, “ARP Offload” or “NS Offload” or similar enabled within the Advanced Properties of the Network Interface Card (accessed through the Device Manager) signifies Base Capability or better. For systems with a dual Network Interface Card (NIC) configuration, only one NIC configuration needs to comply. The manufacturer can provide further guidance on how to confirm Proxy Support.

                                          (iv)

                                          For Notebooks, Desktops, and Integrated Desktops that use an alternative low power mode in place of System Sleep Mode, power in Long Idle (PLONG_IDLE) may be used in place of power in Sleep (PSLEEP) in Equation 1 if the alternative low power mode is less than or equal to 10 watts. In such instances, (PSLEEP
                                              × TSLEEP
                                             ), is replaced by (PLONG_IDLE
                                              × TSLEEP
                                             ); Equation 1 remains otherwise unchanged.

                                          (v)

                                          Notebooks, Desktops, and Integrated Desktops with switchable graphics may not apply the Discrete Graphics allowance, TECGRAPHICS, from Table 7 in Equation 2. However, for Desktop and Integrated Desktop systems providing Switchable Graphics and enabling it by default, an allowance equal to 50 % of the G1 graphics allowance for the platform type (Desktop or Integrated Desktop) may be applied. The switchable graphics incentive only applies to automated switching that is enabled by default. This capability is manufacturer-declared.

                              Representative Models shall be selected for testing per the following requirements:

                                          (i)

                                          For qualification of an individual product configuration, the unique configuration that is intended to be marketed and labelled as ENERGY STAR is considered the Representative Model.

                                          (ii)

                                          For qualification of a Product Family of all product types, with the exception of Workstations, product configurations that represent the worst-case power consumption for each product category within the family are considered Representative Models. When submitting Product Families, manufacturers continue to be held accountable for any efficiency claims made about their products, including those not tested or for which data were not reported.

                                          (iii)

                                          For systems that meet the definition for multiple categories (as defined in Section 1.B) depending on the specific configuration, manufacturers will have to submit the highest power configuration for each category under which they would like the system to be ENERGY STAR qualified. For example, a system that could be configured as either a Category 0 or 1 Desktop, as defined in Table 6 would require submittal of the highest power configuration for both categories in order to be ENERGY STAR qualified. If a product could be configured to meet all categories, it would then have to submit data for the highest power configuration in all categories.

                                          (iv)

                                          For qualification of a Product Family of Workstations under the Workstation or Desktop product type, the product configuration that represents the worst-case power consumption with a single GPU within the family is considered the Representative Model.

                                 Note: Workstations that meet ENERGY STAR requirements with a single graphics device may also have a configuration with more than one graphics device be ENERGY STAR qualified, provided the additional hardware configuration is identical with the exception of the additional graphics device(s). The use of multiple graphics includes, but is not limited to, driving multiple displays and ganging for high performance, multi-GPU configurations (e.g. ATI Crossfire, NVIDIA SLI). In such cases, and until such time as SPECviewperf® supports multiple graphics threads, manufacturers may submit the test data for the workstation with the single graphics device for both configurations without retesting the system.

                              4.2.2.

                              A single unit of each Representative Model shall be selected for testing.

                              4.2.3.

                              All units/configurations for which a Partner is seeking ENERGY STAR qualification, must meet the ENERGY STAR requirements. However, if a Partner wishes to qualify configurations of a model for which non-ENERGY STAR qualified alternative configurations exist, the Partner must assign the qualified configurations an identifier in the model name/number that is unique to ENERGY STAR qualified configurations. This identifier must be used consistently in association with the qualified configurations in marketing/sales materials and on the ENERGY STAR list of qualified products (e.g. model A1234 for baseline configurations and A1234-ES for ENERGY STAR qualified configurations).

                                 Note: There may be cases—as described in the paragraph above—where not all units/configurations will meet ENERGY STAR requirements. If so, the worst-case configuration for test will be the worst-case qualified configuration, and not one of the presumably even higher-energy consuming non-qualified configurations.

                        4.3.   International Market Qualification

                              4.3.1.

                              Products shall be tested for qualification at the relevant input voltage/frequency combination for each market in which they will be sold and promoted as ENERGY STAR.

                        4.4.   Customer Software and Management Service Pre-Provisioning

                              4.4.1.

                              If a manufacturing Partner is hired by a customer to load a custom image on an ENERGY STAR qualified computer, the Partner shall take the following steps:

                                          (i)

                                          Inform the customer that their product may not meet ENERGY STAR with the custom image. A sample notification letter is available on the ENERGY STAR Web site.

                                          (ii)

                                          Encourage the customer to test the product for ENERGY STAR compliance.

                        5.   User Interface

                              5.1.1.

                              Manufacturers are encouraged to design products in accordance with the user interface standard IEEE 1621: Standard for User Interface Elements in Power Control of Electronic Devices Employed in Office/Consumer Environments. For details, see http://eetd.LBL.gov/Controls.

                        6.   Effective Date

                              6.1.1.

                              The date that manufacturers may begin to qualify products as Energy Star under this Version 6.1, will be defined as the effective date of the Agreement. To be ENERGY STAR qualified, a product model shall meet the ENERGY STAR specification in effect on its date of manufacture. The date of manufacture is specific to each unit and is the date on which a unit is considered to be completely assembled.

                              6.1.2.

                              Future Specification Revisions: EPA and the European Commission reserves the right to change this specification should technological and/or market changes affect its usefulness to consumers, industry, or the environment. In keeping with current policy, revisions to the specification are arrived at through stakeholder discussions. In the event of a specification revision, please note that the ENERGY STAR qualification is not automatically granted for the life of a product model.

                        SAMPLE CALCULATIONS

                     I.   Desktop, Integrated Desktop, Notebook Computers: Below is a sample TEC calculation intended to show how levels for compliance are determined based on functional adders and operational mode measurements.
                     Following is a sample ETEC evaluation for a 2,0 GHz, dual core Notebook with Switchable Graphics, 8 GB Memory, Energy Efficient Ethernet (EEE), and 1 hard disk drive (HDD).

                                 A.

                                 Measure values using the ENERGY STAR Computers Test Method:

                                             (1)

                                             (3)

                                             Long Idle State = 8,0 W

                                             (4)

                                             Short Idle State = 10,0 W

                                 B.

                                 Determine the proxy support provided by the operating system and network card. This is a manufacturer-reported parameter.

                                             (1)

                                             On Mac computers, “Wake for network access” enabled within the Energy Saver/Power Adapter Preferences signifies Base Capability or better.

                                             (2)

                                             On Windows computers, “ARP Offload” or “NS Offload” or similar enabled within the Advanced Properties of the Network Interface Card (accessed through the Device Manager) signifies Base Capability or better. OEM can provide further guidance on how to confirm Proxy Support

                                 Determine which Functional Adder Allowances apply:

                                             (1)

                                          Memory: 8 GB installed, so a TECMEMORY allowance of

                                             applies

                                             (2)

                                             Discrete Graphics? No, therefore TECGRAPHICS allowance does not apply.

                                             (3)

                                             Switchable Graphics? Yes, but TECSWITCHABLE allowance does not apply to Notebooks.

                                             (4)

                                             Energy Efficient Ethernet (EEE)? Yes, and assuming one EEE-compliant Ethernet port, a TECEEE allowance of 8,76 × 0,2 × (0,10 + 0,30) = 0,7 kWh applies

                                             (5)

                                             Storage? No, the notebook has only one hard disk drive, so no storage allowance applies.

                                             (6)

                                             Integrated Display? Yes, and assuming a non-enhanced performance, 14 inch display with an area of 83,4 square inches and a resolution of 1,05 megapixels, a TECINT_DISPLAY allowance of 8,76 × 0,30 × (1 + EP) × (2 × r + 0,02×A) = 8,76 × 0,30 × (2 × 1,05 MP + 0,02×83,4 in2) = 9,9 kWh applies.

                                 F.

                                 Calculate ETEC_MAX:

                                             (1)

                                             ETEC_MAX = 22,0 kWh + 6,4 kWh + 0,7 kWh + 9,9 kWh

                                             (2)

                                             ETEC_MAX = 39,0 kWh/yr

                                 G.

                                 Compare ETEC to the ETEC_MAX to determine if the model qualifies:
                                 40,7 kWh/yr > 39,0 kWh/yr
                                 Therefore, the Notebook does not meet ENERGY STAR requirements.

                                             (1)

                                                PTEC_MAX = 0,28× (PMAX + NHDD
                                                 × 5) + 8,76×PEEE×(TSLEEP + TLONG_IDLE + TSHORT_IDLE)

                                             (2)

                                                PTEC_MAX
                                                 = 0,28×(180 + 2 × 5) + 8,76 × 0 × (TSLEEP + TLONG_IDLE + TSHORT_IDLE)

                                             (3)

                                                PTEC_MAX
                                                 = 53,2 + 0

                                 E.

                                 Compare PTEC to the ENERGY STAR levels to determine if the model qualifies:
                                 40,6 W ≤ 53,2 W
                                 Therefore, the Workstation meets ENERGY STAR requirements.

                                 Ambient Temperature: Ambient temperature shall remain between 18 °C and 28 °C, inclusive, for the duration of the test.

                                 C.

                                 Relative Humidity: Relative humidity shall remain between 10 % and 80 %, inclusive, for the duration of the test.

                                 D.

                                 Light Measuring Device (LMD): All LMDs shall meet the following specifications:

                                             (1)

                                             Accuracy: ± 2 % (± 2 digits) of the digitally displayed value; and

                                             (2)

                                             Acceptance Angle: 3 degrees or less.

                                       The overall tolerance of LMDs is found by taking the absolute sum of 2 %of the targeted screen luminance and a 2 digit tolerance of the displayed value's least significant digit. For example, if the screen luminance value is 90 candela per meter squared (cd/m2) and the LMD's least significant digit is a tenth of one cd/m2, 2 % of 90 cd/m2 would be 1,8 cd/m2 and a 2 digit tolerance of the least significant digit would be 0,2 cd/m2. Thus, the displayed value would need to be 90 ± 2 cd/m2 (1,8 cd/m2 + 0,2 cd/m2).

                                    Note: The term “nit” is sometimes used instead of the official SI unit cd/m2. One nit is equivalent to one cd/m2.

                                 E.

                                 Power Meter: Power meters shall possess the following attributes:

                                                         (a)

                                                         0,01 W for measurement values less than 10 W;

                                                         (b)

                                                         0,1 W for measurement values from 10 W to 100 W; and

                                                         (c)

                                             (4)

                                             Measurement Accuracy: Measurement uncertainty as introduced by the instrument that measures the input power to the unit under test (UUT), including any external shunts.

                                                         (a)

                                                         Power measurements with a value greater than or equal to 0,5 W shall be made with an uncertainty of less than or equal to 2 % at the 95 % confidence level.

                                                         (b)

                                                         Power measurements with a value less than 0,5 W shall be made with an uncertainty of less than or equal to 0,01 W at the 95 % confidence level.

                     5.1.   Guidance for Implementation of EN 62623

                     The Test Conduct shall be carried out according to the requirements in European Standard EN 62623:2013 (identical to IEC 62623:2012) “Desktop and Notebook Computers — Measurement of Energy Consumption” reference with the following guidance.

                                 A.

                                 Small-Scale Servers, Thin Clients, and Workstations shall be configured in a manner identical to Desktops (non-integrated) unless otherwise specified. Slates/Tablets shall be configured in a manner identical to Notebooks unless otherwise specified. Portable All-In-One Computers shall be configured in a manner identical to Integrated Desktops unless otherwise specified.

                                             (1)

                                             Thin Clients shall run intended terminal/remote connection software during all tests.

                                 B.

                                 Wake on LAN (WoL) settings shall be in as shipped condition for testing Sleep Mode and Off Mode.

                                 C.

                                 For models that do not offer a Sleep Mode enabled by default, Section 6.2 shall measure power in the lowest-latency user-activated mode or state that preserves machine state and is enabled by default.

                                             (1)

                                             If no such state separate from Long Idle State or Off Mode exists, the measurement in Section 6.2 shall be skipped.

                                 D.

                                 For Long Idle Mode Testing (Section 6.3), the UUT shall be allowed no more than 20 minutes from the point of ceased user input before measurements must be started. If any default settings cause the UUT to enter Long Idle after 20 minutes, begin taking measurements when the UUT has reached the 20 minute mark. Display sleep settings shall be set to default for Long Idle Mode Testing.

                                 E.

                                 For Short Idle Mode Testing (Section 6.4), the UUT shall be allowed no more than five minutes from the point of ceased user input before measurements must be taken. Display sleep settings shall be disabled for Short Idle Mode Testing. If any other default settings cause the UUT to exit Short Idle during the measurement time, extend the settings so that the UUT remains in short idle for the duration of the measurement.

                                 F.

                                 Desktops, Integrated Desktops, Notebook Computers, Portable All-In-One Computers, and Slates/Tablets shall be tested for Idle, Sleep, and Off Mode with Full Network Connectivity (“Proxying”) features using the as shipped setting.

                                 G.

                                 Cellular network connections shall be disabled for testing. Additionally, Bluetooth should be left as-shipped.

                           5.2.   Preparing Display Luminance of Notebooks, Integrated Desktops, Slates/Tablets and Portable All-In-One Computers

                                 A.

                                 Before performing any tests, disable display dimming, display Sleep Mode, Computer Sleep Mode, and automatic brightness control (ABC) in the Computer settings. Document all settings that were changed from the default configuration.

                                             (1)

                                             If ABC cannot be disabled, position a light source such that at least 300 lux directly enters the ABC sensor.

                                 B.

                                 Display the three vertical bar video signal as defined in section 3.2.1.3 of European Standard EN 60107-1:1997 (identical to IEC 60107-1:1997) “Methods of measurement on receivers for television broadcast transmissions — Part 1: General conditions — Measurements at radio and video frequencies”.

                                 D.

                                 With the LMD, measure the luminance in the centre of the display.

                                 E.

                                 Calibrate the UUT display brightness to the closest brightness setting that is at least 90 cd/m2 for Notebook Computers, at least 150 cd/m2 for Integrated Desktop Computers, Portable All-In-One Computers and Slates/Tablets. If the UUT's brightest setting cannot achieve the specified brightness, then set the UUT display to the brightest setting.

                                 F.

                                 the display shall be configured with the ENERGY STAR test image, which can be found in https://www.energystar.gov/ia/partners/images/ComputerTestingImage.bmp.

                     7.1.   Maximum Power Test

                     The maximum power for Workstations is found by the simultaneous operation of two industry standard benchmarks: Linpack to stress the core system (e.g., processor, memory, etc.) and SPECviewperf® (latest available version for the UUT) to stress the system's Graphics Processing Unit (GPU). This test shall be repeated three times on the same UUT, and all three measurements shall fall within a ± 2 % tolerance relative to the average of the three measured maximum power values. The average power should be used for qualification and/or TEC calculations.
                     Additional information on these benchmarks, including free downloads, can be found at the following locations as specified in Table 15.

                     Below are some typical starting values for the use of Linpack for testing Workstations. These values are starting points and not meant to be binding. The tester is free to use the settings most advantageous to their UUT. Platform and Operating System (OS) will have a significant impact on the applicability of these starting values. The below assumes Linux as the test OS.

                                 The matrix size (the combination of number of equations and leading dimensions of array) should be the maximum size that will fit in the Random Access Memory (RAM) on the machine. This AWK script will calculate matrix size on a Linux machine:

                                 Use the output of this to determine what matrix size to input for both the “Number of equations” and “Leading dimensions of array” inputs. The “Number of equations” will be equal to the printed output. The “Leading dimensions of the array” will be the output rounded up to the nearest multiple of eight.
                                 This calculation can be most easily calculated by taking the memory size, in bytes, of the UUT (denoted as m) and substituting m in Equation 1.
