HP OmniBook 4100 Removal and Replacement 2-17
Hint
In the next step, while removing the motherboard, reach through the RAM opening and separate
the case from the PCA. Otherwise, the PCA sticks in the bottom case.
19. Lift the front edge of the motherboard until it clears the hard drive compartment in the bottom
case and frees itself from the bottom case. Then slide the PCA forward and lift it out.
The docking doors may come out while you are removing the motherboard.
