System board
Follow the instructions to replace the system board.
Important notices for handling the system board:
When handling the system board, read the following:
• Some components mounted on a system board are very sensitive. Improper handling of a system board
can cause damage to those components, and may cause a system malfunction.
• 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.
• Avoid bending a system board and hard pushing to prevent cracking at each BGA (Ball Grid Array)
chipset.
