13) 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:

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 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 yourself 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.
