Hardware Installation
JP2 (for USB 0-3) and JP4 (for USB 4-7) are used to select the
power of the USB ports. Selecting 5V_standby will allow you to use
a USB device to wake up the system.
BIOS Setting
“USB KB Wake-Up From S3” in the Power Management Setup
submenu of the BIOS must be set to Enabled. Refer to chapter 3
for more information.
Important:
If you are using the Wake-On-USB Keyboard/Mouse function for
2 USB ports, the 5V_standby power source of your power sup-
ply must support ≥ 1.5A. For 3 or more USB ports, the
5V_standby power source of your power supply must support
≥ 2A.
