Troubleshooting 6

Introduction

If your computer does not operate correctly, re-read the instructions for the procedures you have performed. If an error occurs within a program, consult the documentation supplied with the program. This section identifies solutions to some possible problems.

Troubleshooting checklist

Before turning on the computer, make sure that:

■The power cord is connected to the AC power-in connector and an AC outlet.

■The AC outlet is supplying power.

■If a power strip is used, it is turned on, and the circuit breaker is set.

■The voltage selection switch on the computer power supply reflects the proper voltage.

Verifying your configuration

If your computer is not operating correctly, the BIOS may contain an invalid configuration parameter. Open the BIOS Setup utility and check your configuration settings. (See “About the BIOS Setup utility” on page 45.)
