sequence list and the exploded view to remove or

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.
