Important notices for handling the system board:

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

vThe 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.

vBe careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite.

vIf 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.

vAvoid rough handling of any kind.

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

vIf 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.

Note: The fan assembly and the backup battery are attached to the system board.
