1. Verify that the power supply is good by installing it on a known working
unit and testing it. If the power supply does not work on the test unit,
replace the power supply.
2.
If the unit does not work properly with the replaced power supply, have the
unit serviced.
1.
Verify that the network is operating and the network cable is working
properly.
2.
Verify that the unit is communicating with the server by having the System
Administrator ping the unit from the server:
If the thin client pings back, then the signal was accepted and the unit
is working. This indicates a configuration issue.
If the thin client does not ping back and the thin client does not
connect to the server, re-image the unit.

Reconnect keyboard with computer

Check connector for bent or missing
pins.

Ensure that none of the keys are
depressed.
