Jumpers - Asus P4S8X User Manual

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 x 3 pin USBPWR_12, _34, _56)
The default setting, [1-2] (+5V) disables the USB wake-up feature. Reset
these jumpers to pins [2-3] (+5VSB) to wake up the computer using USB
devices.
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. Also note that ONLY USB +5VSB can
support S3 resume function.
