Assembly Procedures
After the computer has been disassembled and the part that caused the fault has been repaired or
replaced, the computer must be reassembled.
Take note of the following general points when assembling the computer.
• Take your time and follow the instructions carefully. Hurrying the assembly work will
only introduce new problems.
• Check that all cables and connectors are securely connected.
• Before fastening FRUs or other parts in place, ensure that no cables are caught on screws
or the FRU.
• Check that all latches are securely closed.
• Ensure that you have installed all FRUs correctly and do not have any screws left over.
Using an incorrect screw may damage the thread or screw head and result in the FRU not
being securely fastened in place.
After installing FRUs, check that the computer operates correctly.
