Disassembly Procedures
The computer has two basic types of cable connectors:
•
Pressure Plate Connectors
•
Coaxial Cable Connectors
•
Normal Pin Connectors
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. 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.
Coaxial cables should be disconnected with an antenna coaxial disconnector.
Standard pin connectors are used with all other cables. These 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.
Install all the removed FRUs following the steps described in the corresponding sections in this
chapter.
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 assembling the computer.
•
Make sure all cables and connectors are securely fastened.
•
Before securing the FRU or other parts, make sure that screws or the FRU will pinch
no cables.
•
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.
