NEC VT 300 Series manual Battery Replacement

Battery Replacement

The system board uses a battery to maintain system configuration information. The battery is a coin-cell battery mounted on the system board (see the following figure). If it fails to maintain system configuration information, replace it with an identically rated battery from the same manufacturer.

!WARNING

The battery can explode if it is incorrectly replaced or improperly discarded. Use only the same type battery or an equivalent type recommended by the manufacturer when replacing the battery.

Lithium acts as a catalyst when exposed to water and causes spontaneous combustion on contact. Discard used batteries according to the manufacturer’s instructions.

!CAUTION

Removing the battery from the system board causes the computer to lose system configuration information. Prior to removing the battery, run the BIOS Setup utility (see Chapter 3) and print out or write down your system configuration settings. Then you can restore your system to its previous settings.

If you need to replace the battery, follow these steps.

1.Turn off and unplug the computer and any external components connected to it.
