Before removing any FRU, power-off the computer,
unplug all power cords from electrical outlets, remove
the battery pack, then disconnect any interconnecting
cables.
Safety Notice 1: Translation on page 7
Before the computer is powered-on after FRU
replacement, make sure all screws, springs, or other
small parts are in place and are not left loose inside
the computer. Verify this by shaking the computer
and listening for rattling sounds. Metallic parts or
metal flakes can cause electrical shorts.
Note: Before removing any FRU, remove any attached
devices, including the diskette drive, diskette drive
cable, and MultiPort II if they are attached.
