5.Clear RTC RAM (3-pin CLRTC1)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. The RAM data in CMOS, that include system setup information such as system date, time, and system setup parameters, and passwords, is powered by the onboard button cell battery.

To erase the RTC RAM:

1.Turn OFF the computer and unplug the power cord.

2.Remove the onboard battery.

3.Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.

4.Re-install the battery.

5.Plug the power cord and turn ON the computer.

6.Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.
