Verifying the configuration

If the system is not operating correctly, the BIOS may contain an invalid configuration parameter. Enter the BIOS Setup program and check the configuration settings. Lost or incorrect Setup settings may mean a failed battery.

Troubleshooting guidelines

As you troubleshoot the system, follow these guidelines:•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 power is disconnected, stored energy in the monitor components can cause a painful or harmful shock.

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

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

•Only qualified personnel should open the system for maintenance.

•If you are qualified to maintain the system yourself, make certain you are properly grounded before opening the system chassis. See “Static electricity precautions” on page 2, for more information on preventing electrostatic damage to the system.
