Internal 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.
Asimple 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
