2.7 Jumpers
The jumpers on the motherboard allow you to change some feature
settings to suit your customized system configuration.
1. USB device wake-up (3-pin USBPWR01, USBPWR23)
Set these jumpers to pins 1-2 (Enabled) to wake up the computer
using the connected USB devices. Set to pins 2-3 to disable the USB
wake-up feature. These jumpers are set to pins 2-3 (Disabled) by
default.
The USB device wake-up feature requires a power supply that can
provide at least 1A on the +5VSB lead. If this requirement is not met,
the system does not power up. The total current consumed must NOT
exceed the power supply capability (+5VSB) whether under normal
condition or in sleep mode.
