11. Clear RTC RAM (2-pin CLRTC)
This header allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, and system setup parameters by erasing the CMOS
RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which
include system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the two pins.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
If the steps above do not help, remove the onboard battery and short the two pins again to
clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
