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.

If your system is not operating correctly, the BIOS may contain an invalid 
configuration parameter. Enter the BIOS program and check your 
configuration settings, see “BIOS Setup” on page 79 for complete 
instructions.

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

•

Never remove the system cover while the system is turned on.

•

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

•

If a peripheral such as the keyboard, mouse, drive, or printer does 
not appear to work, verify 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 
certain you are properly grounded before opening the system 
chassis. See Chapter 1, “System Access”, for more information on 
preventing electrostatic damage to the system.
