In the U. S. and Canada, the ThinkPad 370C and

EasyServe.
This hardware maintenance manual covers information
about the following IBM ThinkPad models:
355, 360, 750 (monochrome)
355C, 360C, 360CE, 370C, 750C, 755C (TFT color)

When information affects only a specific model, the model
number is shown in parenthesis in the heading or is
explained in the text. Before you go to the checkout guide,
be sure to read this section.
Be extremely careful during write operations such
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 can be written over.
Replace FRUs only for the correct model. When
you replace the FRU, make sure the model of the
machine and FRU part number are correct by
referring to the part list.
FRUs should not be replaced because of a single,
un-reproducible failure. Single failures can occur
from a variety of reasons that have nothing to do with
a hardware defect such as: cosmic radiation,
electrostatic discharge, or software errors. FRU
replacement should only be considered when a
recurring problem exists. If this is suspected, clear
the error log and run the test again. Do not replace
any FRUs if log errors do not reappear.
The servicer must include the following in the parts
exchange form or part return form that is attached to the
returned FRU.
1. Name and phone number of servicer.
2. Date of service.
3. Date when part failed.
4. Date of purchase.
5. Failure symptoms, error codes appearing on
display, and beep symptoms.
6. Procedure index and page number in which
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.
