1230 System board and base cover
Important notices for handling the system board:
When handling the system board, bear the following in mind.
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 At every point in the process, be sure not to drop or stack the system board.
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.
Important notices for RAID setting:
Before you replace the system board, make sure that you read "Installing and
configuring RAID" on page 47, and have the necessary information.
After you replaced the system board, you need to recover the RAID mode in
BIOS Setup Utility menu as follows:
Config -> Serial ATA (SATA) -> SATA Controller Mode Option ->
Compatibility/AHCI/RAID
