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).
2. Keyboard & USB device wake-up (3-pin KB_USBPWB)
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,

• 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 conditions or in sleep mode.
