Introduction

What you need

Step 1

              Lower Case
  • Remove the following ten screws:
  • Three 14.4 mm Phillips #00 screws
  • Three 3.5 mm Phillips #00 screws
  • Four 3.5 mm shouldered Phillips #00 screws
  • When replacing the small screws, align them perpendicular to the slight curvature of the case (they don’t go straight down).

Step 3

              Battery Connection
  • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.
  • It is useful to pry upward on both short sides of the connector to “walk” it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

Step 5

              Fan
  • Use the edge of a spudger to gently pry the fan connector up and out of its socket on the logic board.
  • It is useful to twist the spudger axially from beneath the fan cable wires to release the connector.
  • The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.
