NOTE:
To prevent damage to THIN HEAD screws, use type 0 bit philips screwdriver.
Use, however, the PH point size “1” screwdriver for screws fixing the memory
slot cover and keyboard. Press along the axis of the screwdriver while turning
the screw. This is because the contact area between the screw and driver is less
than for a pan head screw (standard pan-shaped screw head).
