3.2.4 PS/2 Keyboard and Mouse
PS/2 mice and keyboards are connected via standard mini-DIN connectors. If you want to use the
keyboard or mouse to wake up the board from standby or suspend mode you have to activate this
functionality by adjusting the KBPWR jumper settings (page 50). With this jumper you can switch from
normal power supply (VCC) to standby power supply (SVCC) for keyboard/mouse. Some relevant
settings will have to be adjusted in BIOS setup.
