THE TROUBLESHOOTING PROCEDURES
The following pages define the various troubleshooting procedures listed in the previous section. We
assume you are familiar with the placements of various buttons and switches on the computer—such as
the reset and power buttons; if not, refer to the illustrations in Chapter 2.
Procedure #1: Check Power/Run/Memory Lights
A. Are the power light and fan on? If yes, go to Step B. If the fan is on but the power light isn't, your
power light may be burnt out. Go to Step B.
