This chapter instructs you on how to deal with common system
problems. Read it before calling a technician for service.
Solutions to more serious problems require opening up the
system. If you do not know how to deal with the problem, we
advise that you contact your dealer or an authorized service
center for assistance.
The following is a list of the most common things to check when
you encounter problems.
1. Make sure the power switch of the system and each
peripheral device is turned on.
2. Make sure all cables and power cords are tightly connected.
3. Make sure the electrical outlet to which your peripheral
devices are connected is working. Test the outlet by plugging
in a lamp or other electrical device.
4. Make sure the monitor is turned on.
5. Make sure the display’s brightness and contrast controls are
adjusted properly.
When the computer is turned on, nothing happens.
Make sure one end of the AC power cord is plugged into a live
outlet and the other end properly plugged into the back of the
system.
The display screen remains dark after the system is turned
on.
1. Make sure that the monitor’s power switch is on.
2. Make sure one end of the monitor’s power cord is properly
attached to the monitor and the other end is plugged into a
working AC outlet. If necessary, try another outlet.

brightness control knob.
