Re: galaxy tab 3 won't charge or turn on. Samsung does *not* have ports that hold up well when you snag the cable or try to force it in upside down. My three year old, 7oz Echo can be swung around dangling from its original cable.Sturdiest microUSB I have ever seen.e: galaxy tab 3 won't charge or turn on.

The system unit, sometimes called the chassis, is a box-like case housing the electronic components of a computer that are used to process data. System unit components include the processor, memory module, cards, ports, and connectors.
In effect, an electrical ground drains away any unwanted buildup of electrical charge. When a point is connected to a good ground, that point tends to stay at a constant voltage, regardless of what happens elsewhere in the circuit or system. chassis ground is a connection to the main chassis of a piece of electronic or electrical equipment. In older appliances and in desktop computers, this is a metal plate, usually copper or aluminum. In some modern equipment, it is a foil run on the main printed circuit board, usually running around the periphery.
