Select Warranty Lookup. Input the machine type and the serial number. Use the system board listed on
PEW.
Important notices for handling the system board:
When handling the system board, bear the following in mind.
• The system board has an accelerometer, which can be broken by applying several thousands of G-forces.
Note: Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench
can subject the accelerometer to as much as 6,000 G's of shock.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or
composite.
• If a system board is dropped, you must test it, using PC-Doctor for DOS if the system supports PC-Doctor
for DOS, to make sure that the HDD Active Protection System™ still functions.
Note: If the test shows that the HDD Active Protection System is not functioning, be sure to document the
drop in a reject report, and replace the system board.
• Avoid rough handling of any kind.
• At every point in the process, be sure not to drop or stack the system board.
• If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or
conductive corrugated material.
After replacing the system board, run PC-Doctor for DOS to make sure that HDD Active Protection still
functions. The procedure is as follows:
1. Place the computer on a horizontal surface.
2. Run Diagnostics ➙ ThinkPad Devices ➙ HDD Active Protection Test.
Attention: Do not apply physical shock to the computer while the test is running.
