If You Have a Problem 4-9
REPLACING THE CMOS BATTERY
A 3-volt lithium battery in your computer maintains system
configuration information. In the event that this CMOS
battery fails to maintain system configuration information,
replace the battery.
!
CAUTION
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.
!
WARNING
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 used batteries according to the
manufacturer’s instructions.
If you need to replace the battery, follow these steps:
1. Turn off and unplug the system unit and any external
option connected to it.
2. Remove the system unit cover.
