For precautionary purposes, we advise that you disconnect the battery connector from the logic board to avoid any electrical discharge. This step is optional and is not required.
Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.
It may be easier to use your fingernails to lift up on both sides of the connector.
Lift the hard drive by its pull tab and pull it away from the upper case, minding the cable still attaching it to the logic board.
In some revisions of the MacBook A1342, the hard drive bracket may include two rubber brackets (as highlighted in the second picture.) The correct orientation of the rubber brackets is shown in the third picture.
awesome guide! This really made it so easy to figure out exactly what I was doing. The large, sharp pictures really made me feel confident that I was doing everything properly. Thanks!
