2. The AC adaptor and all power and signal cables from the system are unplugged.
3. The battery pack is removed.
NOTE: There are several types of screws used to secure the main unit. The screws vary in length. Please
refer to the screws table after the flowchart. Group the same type of screws together during service

on the wrong location, the long screws may cause irrecoverable damage to the main board.
