    • Carefully lift the metal plate up to expose the motherboard.

      • There is a wire strip running through the metal plate that is soldered to motherboard and power supply board. The plate cannot be completely removed. Do NOT force plate upwards. All the ribbon cables can be safely unplugged by simply pulling them out of their slots.

    The yellow circles in this diagram are incorrect. There are 3 screws on the main board assembly. 2 on the left and one correctly indicated on the bottom right. The top right yellow circle does not belong.
