Helpful Hints
If you encounter some minor problem with your workstation,
monitor, or software, refer to the following list of general
suggestions before taking further action:
■ Check that the workstation and monitor are plugged into a
working electrical outlet.
■ Check to see that the workstation is turned on and the green
power light is on.
■ Check to see that the monitor is turned on and the green
monitor light is on.
■ Turn up the brightness and contrast controls of the monitor
if the monitor is dim.
■
Press and hold any key. If the system beeps, then your
keyboard should be operating correctly.
