Chapter 1. Important safety information

Personal computers manufactured by Lenovo contain a coin cell battery to
provide power to the system clock. In addition, many mobile products, such
as notebook computers, utilize a rechargeable battery pack to provide system
power when in portable mode. Batteries supplied by Lenovo for use with
your product have been tested for compatibility and should only be replaced
with approved parts.
Never attempt to open or service any battery. Do not crush, puncture, or
incinerate batteries or short circuit the metal contacts. Do not expose the
battery to water or other liquids. Only recharge the battery pack strictly
according to instructions included in the product documentation.
Battery abuse or mishandling can cause the battery to overheat, which can
cause gasses or flame to vent from the battery pack or coin cell. If your
battery is damaged, or if you notice any discharge from your battery or the
buildup of foreign materials on the battery leads, stop using the battery and
obtain a replacement from the battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For
some rechargeable batteries (particularly Lithium Ion batteries), leaving a
battery unused in a discharged state could increase the risk of a battery short
hazard. Do not let rechargeable Lithium-Ion batteries completely discharge
or store these batteries in a discharged state.

Rechargeable battery notice

Do not attempt to disassemble or modify the battery pack. Attempting to do
so can cause an explosion, or liquid leakage from the battery pack. A battery
pack other than the one specified by Lenovo, or a disassembled or modified
battery pack is not covered by the warranty.
If the rechargeable battery pack is incorrectly replaced, there is danger of an
explosion. The battery pack contains a small amount of harmful substances.
To avoid possible injury:

Replace only with a battery of the type recommended by Lenovo.

Keep the battery pack away from fire.
Do not expose it to water or rain.
Do not attempt to disassemble it.
Do not short-circuit it.

Avoid subjecting your computer to extreme temperatures (below 5C/41F
or above 35C/95F).
Some appliances, such as certain portable desktop fans or air purifiers, can
produce negative ions. If a computer is close to such an appliance, and is
exposed for an extended time to air containing negative ions, it may
become electrostatically charged. Such a charge may be discharged
through your hands when you touch the keyboard or other parts of the
computer, or through connectors on I/O devices connected to it. Even
though this kind of electrostatic discharge (ESD) is the opposite of a
discharge from your body or clothing to the computer, it poses the same
risk of a computer malfunction.
Your computer is designed and manufactured to minimize any effects of
electrostatic charge. An electrostatic charge above a certain limit, however,
can increase the risk of ESD. Therefore, when using the computer close to

Notice on deleting data from your hard disk -----------------------As computers spread into every corner of life, they process more and more
information. The data on your computer, some of it sensitive, is stored on a
storage device called the hard disk. Before you dispose of, sell, or hand over
your computer, you need to delete that data.
Handing your computer over to someone else without deleting the loaded
software, such as operating systems and application software, may even
violate License Agreements. You are advised to check the terms and
conditions of those Agreements.
Deleting the data from the hard disk is not easy.
There are methods that seem to delete the data:
Move the data to the recycle bin, and then choose the Empty recycle bin
Use the Delete command.
Format your hard disk, using the software for initializing it.
Using the preinstalled recovery program, bring the hard disk back to
factory-ship state.
These operations, however, only change the file allocation of the data; they
do not delete the data itself. In other words, the data retrieval processing is
disabled under an operating system such as Windows. The data is still there,
even though it seems to be lost. Thus, it is sometimes possible to read the
data by use of special software for data recovery. There is a risk that people
of bad faith may read and misuse the critical data on hard disks for
unexpected purposes.
To prevent the leakage of data, it becomes very important that you take
responsibility for deleting all the data from the hard disk when you dispose
of, sell, or hand over your computer. You can destroy the data physically by
smashing the hard disk with a hammer, or magnetically by means of strong
magnetic power, thus making the data unreadable. But we recommend that
you make use of the software (payware) or service (pay service) specifically
developed for the purpose.
