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.

After installing an FRU in the computer, confirm that the FRU and the computer are functioning properly.
