System board, fan assembly, and backup battery Removal and Installation - ThinkPad Edge E10, Edge 11

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.
  • 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.

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

For access, remove these FRUs in order:

Following components soldered on the top side of the system board are extremely sensitive. When you service the system board, avoid any kind of rough handling.
