11) CLR_CMOS(ClearingCMOSJumper)
Use this jumper to clear the CMOS values (e.g. date information and BIOS congurations) and reset
the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to
temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few
seconds.
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) or manually congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS
congurations).
Open: Normal
Short: Clear CMOS Values
12) BAT(Battery)
The battery provides power to keep the values (such as BIOS congurations, date, and time information)
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.

Turn off your computer and unplug the power cord.1.
Gently remove the battery from the battery holder and wait for one minute. 2.
(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.)
Replace the battery. 3.
Plug in the power cord and restart your computer.4.
Always turn off your computer and unplug the power cord before replacing the battery. •
Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with •
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).
Used batteries must be handled in accordance with local environmental regulations. •
