1200 System Board - ThinkPad T14 Gen 1 Hardware Maintenance Manual

1200 System board

Important notices for handling the system board:
When handling the system board, read the following:
• The system board has an accelerometer, which can be broken when several thousands of G-forces are
applied.
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 6000 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 a
corrugated conductive surface.
Note: If the new system board does not come with a new M.2 solid-state drive thermal pad, it is suggested
that you order an extra thermal pad in case the old thermal pad is damaged during replacement.
