2. Keyboard and USB device wake-up (KB_USBPWB)

This jumper allows you to enable or disable the P/S 2 device wake-up feature. When

you set this jumper to pins 2-3 (+5VSB), you can wake up the computer by pressing a

key on the P/S 2 keyboard or by clicking on the P/S 2 mouse. This feature requires an

ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding

setting in the BIOS.

2. 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. 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.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default

position. Removing the cap will cause system boot failure!

• If the steps above do not help, remove the onboard battery and move the jumper

again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the

battery.

• You do not need to clear the RTC when the system hangs due to overclocking. For

system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature.

Shut down and reboot the system, then the BIOS automatically resets parameter

settings to default values.
