2.Real Time Clock (RTC) RAM (RTCLR)

The CMOS RAM is powered by the onboard button cell battery. To clear the RTC data: (1) Turn off your computer and unplug the AC power, (2) Move this jumper to Clear CMOS, (3) Move the jumper back to Keep CMOS, (4) Turn on your computer, (5) Hold down <Delete> during bootup and enter BIOS setup to re-enter user preferences.

Battery Test Jumper (RTCLR)

You can test the battery’s current by removing this jumper and attaching a cur- rent meter to pins 1 & 2.

WARNING! You must unplug the power cord to your power supply to ensure that there is no power to your motherboard. The CMOS RAM containing BIOS setup information may be cleared by this action. You must enter BIOS to “Load Setup Defaults” and re-enter any user information after removing and reapplying this jumper.
