1. Slowly push the cover bracket from the right [1] about 4 cm (1½") to the left to disengage the hook
below then lift the plate to remove it.
• Apply only enough force to slide the bracket off of its hook.
• If you push too hard, the bracket may release suddenly from the frame and the edge of the cover
may shear components from the control board.
2. Touch a metal surface before you touch the control board.
3. Push the corner of the back cover [2] aside to expose the screw.
4. Remove the control board [3] (
x12, FFC x2,
x6).
5. The NVRAM is on the bottom of the board. Turn the board over and lay it on a flat, clean surface so
you can see the NVRAM [4].
