Important notices for handling the system board:

When handling the system board, bear the following in mind.

v At every point in the process, be sure not to drop or stack the system board.

v 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.

v Be careful not to drop the system board on a bench top that has a hard

surface, such as metal, wood, or composite.

v If a system board is dropped, you must test it, using PC-Doctor for DOS, to

make sure that the HDD Active Protection still functions (see below).

Note: If the test shows that HDD Active Protection is not functioning, be sure

to document the drop in any reject report, and replace the system board.

v Avoid rough handling of any kind.

v 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.
