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.
