Replacing field-replaceable units (FRUs)

Before replacing FRUs

Before replacing any Field Replaceable Units (FRUs), read the following:

• Only certified and trained personnel can service the computer.

• Before replacing an FRU, read the entire section about replacing the part.

• Be extremely careful during writing operations such as copying, saving, or formatting.

The sequence of the drives in the computer that you are servicing might have been altered. If you select

an incorrect drive, data or programs might be overwritten.

• Replace an FRU only with another FRU of the correct model.

When you replace an FRU, ensure that the model of the machine and the FRU part number are correct by

referring to the website http://www.lenovo.com/serviceparts-lookup.

• An 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 an FRU only when a

problem recurs. If you suspect that an FRU is defective, clear the error log and run the test again. If the

error does not recur, do not replace the FRU.

• Only replace a defective FRU.

To check the locations of FRUs, see

Do not open your computer or attempt any repairs before reading the Important

Product Information Guide.
