Troubleshooting

Before turning on the system, make sure that:

The power cord is connected to the AC power-in connector and an AC 
outlet.

The AC outlet is supplying power.

If a power strip is used, it is turned on, and the circuit breaker is set.

The voltage selection switch on the system power supply reflects the 
proper voltage.

If your system is not operating correctly, the BIOS may contain an invalid 
configuration parameter. Enter the BIOS Setup utility program and check your 
configuration settings.

As you troubleshoot your system, keep the following guidelines in mind:

Never remove the chassis cover while the computer is turned on.

Do not attempt to open the monitor. Even if the monitor’s power is 
disconnected, stored energy within the monitor’s components can offer 
a painful or harmful shock.

If a peripheral, such as the keyboard, mouse, drive, or printer does not 
appear to work, make sure that all connections are secure.

If an error message displays on the screen, write it down, word for word. 
You may be asked about it when calling technical support.

Only qualified personnel should open the system for maintenance.

If you feel you are qualified to maintain the system yourself, make sure 
you are properly grounded before opening the system chassis. See “Static 
electricity precautions” on page 17 for more information on preventing 
electrostatic damage to the system.
