If using a USB keyboard, HP recommends connecting the keyboard to one of the USB 2.0 ports with the wake from S4/S5
feature. The wake from S4/S5 feature is also supported on the PS/2 connectors if enabled in BIOS F10 Setup.
When a graphics card is installed in one of the system board slots, the video connectors on the graphics card and the
