Disassembly Procedures
The computer has three basic types of cable connectors:
❑
Pressure Plate Connectors
❑
Normal Pin Connectors
❑
Flexible Cable Connections
To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector's
plastic pressure plate and slide the cable out of the connector - you may have to lift the
connector up in order to remove it and clear an FRU or other part. To connect the cable to a
Pressure Plate connector, make sure the pressure plate is fully lifted, and slide the cable into
the connector. Secure the cable in place by pushing the sides of the pressure plate down so
the plate is flush with the sides of the connector. Gently pull on the cable to make sure the
cable is secure. If you pull out the connector, connect it again making sure the connector's
pressure plate is fully lifted when you insert the cable.
Standard pin connectors and flexible cable connectors can be connected and disconnected by
simply pulling them apart or pushing them together.
Assembly Procedures
After you have disassembled the computer and fixed or repaired the problem that was
causing the computer to operate abnormally, you will need to reassemble the computer.
While assembling the computer, remember the following general points:
❑
Take your time, making sure you follow the instructions closely. Most problems arise
when you get in a hurry re-assembling the computer.
❑
Make sure all cables and connectors are securely fastened.
❑
Before securing the FRU or other parts, make sure that no cables will be pinched by
screws or the FRU.
❑
Check that all latches are closed securely in place.
❑
Make sure all the correct screws are used to secure all FRUs. Using the wrong screw
can either damage the threads on the screw or the head of the screw, and may prevent
proper seating of an FRU.
After installing an FRU in the computer, confirm that the FRU and the computer are
functioning properly.
