Troubleshooting

This chapter tells you how to troubleshoot your hardware. Specifically, it covers:
• troubleshooting to see if you have a faulty part
• ordering a new part
• removing the faulty part
• installing the new part
There are four ways to diagnose hardware problems:
• Power-on tests—tests your major hardware parts as the system boots up. If a part is
faulty, the system notifies you with the LED and error messages.
• Diagnostic tests —more comprehensive tests of your system's hardware. The
system informs you if it finds a faulty part.
• Confidence tests—used if you think you have a problem with your keyboard,
mouse, or monitor, or with a peripheral. The confidence tests verify which parts are
working correctly.
