Procedure

Important: The following image shows the memory cards and hard drive installed in the battery
bay. Note the correct position of the memory card levers.  

mc196.jpg

Caution: The remaining images pictured in this procedure used a pre-production model, so the
direction and appearance of the levers difer from the computer that you are servicing. However,
the steps should be the same.

1.On the underside of the logic board, use light pressure with a Phillips screwdriver to remove
the 3-mm long lever screw. (Remove both screws if replacing both levers.)

mc197.jpg

2.Lift of the lever, and remove the spring.
