  • The right side of bottom case should separate from the top case when you remove the sliding shaft.

  • Do not pull up too far or the wire hinge may be damaged.

  • Slide the top case to the right to separate the joint.

  • Weave the wires and ribbons through the wire hinge to completely separate the top and bottom casings.

Add Comment

  • The speakers are soldered to the ribbon cable attached to the upper LCD, so they must be removed at the same time as the LCD.

  • Lift the top LCD out of the plastic frame. Carefully thread the ribbon cable out of the hinge to avoid damaging it.
