Troubleshooting Without Diagnostics

Helpful Hints

If you encounter some minor problems with your computer, monitor, or software, see the following list of general suggestions before taking further action:

Check that the computer and monitor are plugged into a working electrical outlet.

Check to see that the computer is turned on and the green power light is on.

Check to see that the monitor is turned on and the green monitor light is on.

Turn up the brightness and contrast controls of the monitor if the monitor is dim.

Press and hold any key. If the system beeps, then your keyboard should be operating correctly.

Check all cable connections for loose connections or incorrect connections.

Reconfigure your computer after installing a non–plug and play expansion board or other option. See “Solving Hardware Installation Problems” for instructions.

Be sure that all the needed device drivers have been installed. For example, if you are using a printer, you need a driver for that model printer.

Remove all diskettes from your system before turning it on.

If you have installed an operating system other than the factory-installed operating system, check to be sure that it is supported on your system.

If your system has an AGP card installed (on select models only), the monitor must be plugged into the monitor connector on the AGP card. The other monitor connector is disabled and if the monitor is connected into this port, the monitor will not function.

ÄCAUTION: When the computer is plugged into an AC power source, there is always voltage applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
