Flip the device over, so the backside is facing up.

Use a Phillips #00 screwdriver to remove four 4.00 mm screws.

Use the Phillips #00 screwdriver to unscrew or loosen two captive screws at the right and left corner near the hinges.

The last two screws should remain in the back case and can't be removed.

Three of the screws are dummy screws, only screwed into retainers. They are not holding anything in and can be left in place for simplicity.
