A newly connected unknown USB

peripheral does not respond or USB

peripherals connected prior to the newly

connected USB peripheral will not

complete their device actions.

An unknown USB peripheral may be connected and disconnected to a running

platform as long as you do not reboot the system. If problems occur, disconnect

the unknown USB peripheral and reboot the platform.

Video does not display. 1. Verify that the monitor brightness is set to a readable level.

2. Verify the monitor is good by connecting it to a known working computer

and ensure its front LED turns green (assuming the monitor is Energy Star

compliant). If the monitor is defective, replace it with a working monitor

and repeat testing.

3. Re-image the thin client unit and power on the monitor again.

4. Test the thin client unit on a known working monitor. If the monitor does

not display video, replace the thin client unit.
