Replacing The Cmos Battery - NEC POWERMATE VE - 03-1996 Manual

REPLACING THE CMOS BATTERY

All system boards use a battery to maintain system
configuration. Some system boards use a 3-volt lithium
battery. If your system uses this type of battery (see the
following figure) and it fails to maintain system
configuration information, replace it with an identically
rated battery from the same manufacturer.
Removing the battery from the system board
causes the computer to lose system configuration
information. If you can, run the Setup Utility and
print out or write down your system configuration
settings. Then you can restore your system to its
current settings.
The battery can explode if it is incorrectly replaced
or improperly discarded. Use only the same 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
manufacturer's instructions.
If you need to replace the battery, follow these steps:
1. Turn off and unplug the computer and any external
components connected to it.
