3. USB device wake-up (3-pin USBPWR12, USBPWR34, USBPWR56,
USBPWR78)
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).
2. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard wake-up feature. Set
this jumper to pins 2-3 (+5VSB) if you wish to wake up the computer when you
press 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.
•
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.
