System board and ExpressCard slot assembly removal and installation - ThinkPad X200 Tablet, X201 Tablet

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, 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.
  • 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.
