Important notices for handling the system board:
When handling the system board, bear the following in mind.
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
At every point in the process, be sure not to drop or stack the system board.
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.
