Important notes
Only certified trained personnel should
service the computer.
Read the entire FRU removal and replacement
page before replacing any FRU.
Use new nylon-coated screws when you
replace FRUs.
Be extremely careful during such write
operations as copying, saving, or formatting.
Drives in the computer that you are servicing
might have been rearranged, or the drive startup
sequence might have been altered. If you select
an incorrect drive, data or programs might be
overwritten.
Replace FRUs only for the correct model.
When you replace a FRU, make sure the model
of the machine and the FRU part number are
correct by referring to the FRU parts list.
A FRU should not be replaced because of a
single, unreproducible failure. Single failures
can occur for a variety of reasons that have
nothing to do with a hardware defect, such as
cosmic radiation, electrostatic discharge, or
software errors. Consider replacing a FRU only
when a problem recurs. If this is suspected,
clear the error log and run the test again. Do not
replace any FRUs if log errors do not reappear.
Be careful not to replace a nondefective FRU.

2. Date of service
3. Date on which the machine failed
4. Date of purchase
5. Failure symptoms, error codes appearing on the
display, and beep symptoms
6. Procedure index and page number in which the
failing FRU was detected
7. Failing FRU name and part number
8. Machine type, model number, and serial number
9. Customer's name and address
