Initial Troubleshooting
The following sections provide initial troubleshooting procedures and tables listing
specific problems, probable causes, and recommended actions to take if the
computer fails after configuring it or after installing optional hardware or software.
Refer to the documentation supplied with the additional options if problems are
encountered after installation.
•
Keep it simple, only troubleshoot one problem at a time. Also, only make
one change at a time. For example, if the IDE hard disk drive fails to boot,
do not try all the suggested actions at once. Instead, start with one
suggestion such as checking the cables. After securing the cables, try
booting the computer. If it does not work, try another suggestion.
•
Look for abnormal computer, keyboard, and monitor LED indications. For
example, make sure the power on LED lights when you turn on the
computer and the drive access indicators light when using either the diskette
drive or hard disk drive.
•
If there are Power On Self Test (POST) error(s), run the BIOS Setup utility
and fix the problem(s) identified by the POST error(s).
•
If you installed external devices, make sure all cables are correctly
connected to the appropriate devices.
•
If you installed devices inside the computer, make sure nothing was bumped
or jarred loose, and that all cable connections are securely in place.
•
Make sure all device drivers are installed correctly.
