4.1 General 4 Replacement Procedures
Disassembly Procedures
The cable connectors come in these two basic types:
Pressure plate connectors
Normal pin connectors
To remove a pressure plate connector, pull up the tabs on either side of the connector's
plastic pressure plate and gently pull the cable out of the connector. To reconnect the cable to
the pressure plate's connector, raise the pressure plate up to a satisfactory height and slide the
cable into the connector. Secure the cable in the correct position by pressing down the sides
of the pressure plate so that the plate is flush with the sides of the connector. Grasp and pull
the cable gently to check that the cable is connected firmly. If the cable comes off the
connector, reinsert the cable by raising the pressure plate up to a satisfactory height.
Normal pin connectors are used for all the other types of cables. These connectors can be
installed or removed by simply inserting them or pulling them out.
Assembly Procedures
You have to reassemble the computer after you have disassembled the computer and fixed
the component that caused the problem.
When reassembling the computer, keep the following general guidelines in mind:
Take your time to carry out the suggested instructions completely. Hurried
reassembly can often cause problems.
Check that all the cable and connectors are fastened securely.
Before securing the FRUs or other parts, check that the cables are not caught by the
screws or FRUs.
Check that all the latches are closed securely.
Check that all the required screws are used to secure the FRUs. Using wrong screws
can damage the threads or heads of the screws or does not ensure that the FRUs are
secure.
After installing a FRU, make sure that the FRU and computer work normally.
