1. To avoid the system unstability after clearing CMOS, we recommend
users to enter the main BIOS setting page to "Load Optimal Defaults"
and then "Save Changes and Exit".
2. Make sure the power supply provides enough 5VSB voltage before
selecting the 5VSB function.
3. It is required that users place the USBPWR_F & USBPWR_R cap onto
2-3 pin rather than 1-2 pin as default if you want to wake up the com-
puter by USB/PS2 KB/Mouse.
