1-24 Chapter 1: Product introduction
2. USB device wake-up (3-pin PS2_USBPW1-4, USBPW5-8, USBPW9-12)
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.
The USBPW1-4 jumpers are for the rear USB ports. The USBPW5-8 and
USBPW910 jumpers are for the internal USB connectors that you can
connect to additional USB ports.
• 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 will not power up.
• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.
