Thebatteryprovidespowertokeepthevalues(suchasBIOScongurations,date,andtimeinformation)
in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a
low level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one
minute. (Or use a metal object like a screwdriver to touch the positive
and negative terminals of the battery holder, making them short for 5
seconds.)
3. Replace the battery.
4. Plug in the power cord and restart your computer.
Always turn off your computer and unplug the power cord from the power outlet before clear- •
ing the CMOS values.
After clearing the CMOS values and before turning on your computer, be sure to remove the •
jumper cap from the jumper. Failure to do so may cause damage to the motherboard.
After system restart, go to BIOS Setup to load factory defaults (select Load Optimized De- •
faults)ormanually conguretheBIOS settings(referto Chapter2,"BIOS Setup,"forBIOS
congurations).

an incorrect model.
Contact the place of purchase or local dealer if you are not able to replace the battery by your- •
self or uncertain about the battery model.
When installing the battery, note the orientation of the positive side (+) and the negative side (-) •
of the battery (the positive side should face up).
