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. Fix the cable to the correct position by pressing down the sides of
the pressure plate so that the plate can be flush with the sides of the connector. Grasp and
pull the cable gently to check that the cable is connected firmly. If the cable came 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 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
reassembling can often cause problems.
Check that all the cable and connectors are fastened securely.
Before fixing 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 fix the FRUs. Using wrong screws can
damage the threads or heads of the screws or does not ensure firm FRU fixing.
After installing an FRU, make sure that the FRU and computer can work normally.
