Warning! To avoid damaging the computer, always turn off the power supply before setting “Clear CMOS.” Before turning on the power supply, set the jumper back to “3.0 V Battery On.”

This jumper is used to erase CMOS data and reset system BIOS information.

The procedure for clearing CMOS is:

1.Turn off the system.

2.Short pin 1 and pin 2.

3.Turn on the system. The BIOS is now reset to its default setting
