nternal Visual Inspection
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.
2. Remove the left computer cover.
3. Verify that all DIMMs and expansion cards as well as the micro-
processor(s) and battery are fully seated in their sockets or connectors.
WARNINGS: The microprocessor can get extremely hot. Be sure the
chip has had sufficient time to cool before you touch it.
To maintain proper air flow and prevent the system from overheat-
ing, each power supply bay must have either a power supply or the
power closeout panel installed.
To ensure that the chips are fully seated in their sockets, press firmly on the
top of each chip.
To reseat a microprocessor, first remove it from its socket and then reinstall
it as described in "Microprocessor and Heat Sink" in Chapter 4.
To reseat a DIMM, remove it from its socket and reinstall it as described in
"DIMMs" in Chapter 4.
If you need to reseat an expansion card, use a
the screw that secures the card-mounting bracket. Grasp the card by its top
corners, and carefully pull it out of its connector. Reinsert the card in its
connector, and carefully push it in until fully seated. Then reinstall the card-
mounting bracket's retaining screw.
