88 Troubleshooting

Troubleshooting checklist

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.

Verifying your configuration

If your system is not operating correctly, the BIOS may contain an invalid

configuration parameter. Open the BIOS Setup utility and check your

configuration settings. (See “About the BIOS Setup utility” on page 67.)

Troubleshooting guidelines

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 power is disconnected,

stored energy in the monitor components can inflict a painful or harmful

shock.

■ If a peripheral does not work, make sure that all connections are secure.

■ If you see an error message 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 are qualified to maintain the system yourself, make sure you are

properly grounded before opening the system chassis. See “Preventing

static electricity discharge” on page 15 for more information on

preventing electrostatic damage to the system.
