14) 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.

You may clear the CMOS values by removing the battery:

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. •

13) 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
