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.
2. Keyboard/mouse power (3-pin PS2_USBPW1-4)
This jumper allows you to enable or disable the keyboard/mouse and USB port 1-4 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 (the default is the Space Bar), clicking the mouse or using
a 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. The USBPW1-4 jumper is for the rear
USB ports.
The total current consumed must NOT exceed the power supply capability (+5VSB) whether under
normal condition or in sleep mode.
