CAUTION: Before you proceed with the internal visual inspection
described in this section, ensure that the user has saved all open files and
exited all open application programs if possible.
A simple visual inspection of a computer's 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 Features" 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
all the AC power cables from their power sources.
WARNING: Before beginning to work inside the computer, discon-
nect the power supply from the power source and the power supply
cables from the power supply.
2. Remove the computer cover as described in "Computer Cover" in
Chapter 4.
3. Verify that the IC chips, DIMMs, expansion cards, and micro-
processor(s) modules, are fully seated in their sockets or connectors.
WARNING: The microprocessor module can get extremely hot dur-
ing system operations. Be sure it has had sufficient time to cool
before touching it.
WARNING: While reseating the microprocessor module, wear a
wrist grounding strap or maintain contact with a metal surface on
the chassis.
