2. Keyboard power (3-pin KBPWR)

This jumper allows you to enable or disable the keyboard 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 keyboard. This feature requires an ATX power supply that can supply at least 1A

on the +5VSB lead, and a corresponding setting in the BIOS.

3. USB device wake-up (3-pin USBPW1-4, 3-pin USBPW5-8)

Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped,

DRAM refreshed, system running in low power mode) using the connected USB

devices. Set to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU,

DRAM in slow refresh, power supply in reduced power mode).

• The USB device wake-up feature requires a power supply that can provide 500mA on

the +5VSB lead for each USB port; otherwise, the system would not power up.

• The total current consumed must NOT exceed the power supply capability (+5VSB)

whether under normal condition or in sleep mode.
