Replacing the service door
Replace the service door after accessing the memory module slot, hard drive, regulatory label, and other components.
To replace the service door:
1.Set the service cover down in place(1), taking care to align it properly, and then slide it toward the battery bay until the service door snaps into place.(2).
2.With the service bay towards you, replace the micro SD enclosure if necessary. Replace the three captive screws at the center of the unit and the two screws at the edge of the unit (3). Replace the rubber covers for the edge screws. Then replace the two screws in the middle of the service door (4).
NOTE: If you want to use the optional screw, it is stored inside the service door.
3.Insert the battery (see Inserting or removing the battery on page 43).
