To erase the RTC RAM:

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

2.Remove the 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.
