About the Lithium Battery
The lithium battery starts to weaken after several years and the system
settings, such as the date and time stored in CMOS RAM, may become
inaccurate. Replace the lithium battery when this occurs.

BIOS Setup utility.
2
Shut down your computer and turn off all peripheral devices, such as
your printer.
3
Unplug your computer and any peripheral devices.

If necessary, remove any cables, add-on cards, or other components to
access the lithium battery.
