2. PS2 and USB device wake-up (3-pin PS2_USBPW1~4)
This jumper allows you to enable or disable the PS2 ports and USB ports 1~4 wake-up
feature. When you set this jumper to pins 2-3 (+5VSB), you can wake up the computer
using a PS2 or USB device. This feature requires an ATX power supply that can supply
at least 1A on the +5VSB lead, and a corresponding setting in the BIOS. This jumper is
for the rear USB ports.
3. USB device wake-up (3-pin USBPW5~8)
Set this jumper 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.
