Wake-On-PS/2 Keyboard/ Mouse

The Wake-On-PS/2 Keyboard/ Mouse function allows you to use the PS/2 keyboard or PS/2 mouse to power-on the system. To use this function:

JP3 must be set to “2-3 On: +5V_standby”. Refer to “PS/2 Power Select” in this chapter for more information.

Confi gure the PS/2 keyboard/mouse wake up function in the Advanced menu

(“ACPI Power Management Confi guration” submenu) of the BIOS. Refer to chapter 3 for more information.

Important:

The +5V_standby power source of your power supply must support

≥720mA.

Make sure to turn off your computer prior to connecting or disconnecting a mouse or keyboard. Failure to do so may damage the system board.

By default, the PS/2 port supports PS/2 keyboard only and/or to support

PS/2 mouse, you must set JP3 accordingly. Refer to “PS/2 Power Select“ on page 28.
