Preliminary Checklist

This section describes some simple, preliminary tests and guidelines for troubleshooting the computer without using the diagnostics.

If you encounter some minor problem with the computer or a software application, go through the following checklist for possible solutions before running any of the diagnostic utilities:

■Are the computer and monitor connected to a working electrical outlet?

■Is the computer turned on?

■Is the green power light illuminated?

■Is the monitor turned on?

■Is the green monitor light illuminated?

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

■Press and hold any key. If the system beeps, then the keyboard is operating correctly.

■Check all cables for loose or incorrect connections.

■Reconfigure the computer after installing a non–Plug and Play expansion board or other option, such as a diskette drive.

■Are all of the necessary device drivers installed?

■Have all printer drivers been installed for each application?

■Remove all diskettes from the diskette drives before you turn on the system.

■Are all switches set correctly?

■Is the NIC Remote Wakeup cable (featured on some models) connected between the NIC and the riser/system board?

■Are all memory sockets filled on computers using RIMMs?

■Ensure that memory module types are not mixed on the same system board. The system will not boot if RIMMs and DIMMs are mixed.
