Clearing the CMOS settings

The Clear RTC RAM (3-pin J19) jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. It also allows clearing of date, time, and system setup parameter memories in CMOS, by erasing the RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, including system setup information.

CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
  1. Turn off the PC and unplug the power cord.
  2. Move the J19 jumper cap from pins 1-2 (normal) to pins 2-3 (clear CMOS).

  3. Keep the J19 jumper cap on pins 2-3 for 5 to 10 seconds, then move back to pins 1-2.
  4. Plug in the power cord and turn on the PC.
  5. Press F1 to enter the BIOS setup and change the BIOS settings.
