Removing and replacing a FRU 1190 System board, PC Card/ExpressCard slots assembly or PC Card/Smart Card slots assembly or PC Card/4-in-1 media reader slot assembly Important notices for handling the system board When handling the system board, bear the following in mind. v At every point in the process, be sure not to drop or stack the system board. v 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. v Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite. v 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. v Avoid rough handling of any kind. v 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.
