Perform the diagnostic tests described in Chapter 2 to determine which FRU is the cause of
the fault.
Do not perform any unnecessary work. Always work in accordance with the disassembly and
re-assembly procedures in this manual.
Keep parts removed from the computer in a safe place away from the computer where they
will not be damaged or interfere with your work.
Disassembling requires the removal of a large number of screws. Keep removed screws in a
safe place such that you can determine which screws belong to which part.
When re-assembling, ensure that you use the correct screws and fit parts in the correct

As all parts have sharp edges and corners, take care not to cut yourself.
After replacing an FRU, check that the computer and replaced part operate correctly.
