A simple visual inspection of a computer³s interior hardware can often lead to
the source of a problem, such as a loose expansion card, cable connector, or
mounting screw. When you perform the visual inspection, refer to ±System
Features² in Chapter 1 to locate components in the inspection procedure.
To perform the internal visual inspection, follow these steps:
1.
Turn off the system, including any attached peripherals, and disconnect
the AC power cable from its power source.
