简介

Replacing the upper case requires the removal of nearly every component in your MacBook Pro. You will also need to transfer your old trackpad over to your new upper case.

  5. 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.

This is a great guide. Just replaced my keyboard after a spill. It's definitely a harrowing experience, especially getting all those 67 microscopic screws holding the keyboard against the top side. But if you sit down with approximately 2 beers (wouldn't recommend more or you'll probably start making mistakes), it's a perfectly manageable 3-4 hour experience. Just take it slow!

If I replace just the keyboard, are there any steps that I can skip?

Duane Wood -

Just finished replacing the top cover assembly. The biggest problem I had was re-inserting the ZIF connectors for the keyboard and backlight. There isn’t enough room for my fat fingers to line up the cable with the socket. The angled tweezers applied carefully (don’t want to puncture or rip the cable) and a little help from a spudger made it happen. When switching the cases check carefully for “missing” parts. Besides the trackpad, the upper case I got from iFixit lacked the center support bracket for the optical drive and logic board, the little screw bracket for the bottom case and the antenna stuck to the case behind the right speaker. The antenna is a little fiddly because it’s stickied to the case and there’s not much room to pry it out without bending and possibly damaging it.

All that said, it wasn’t a particularly difficult job, just labor intensive. And the wife’s reaction to getting her business computer back without buying a new one was worth it.

Raymond Ives -

Just finished this and the only things I would add deal with the metal plate that hold the power meter button in is not mentioned and luckily I was able to slide the cable under the logic board and make the connection. otherwise it would be good to add this step before you re insert the logic board. Also the black and orange rubber part that is the bottom of the hard drive mount. They just lift out of the old case and slide into the new case. And there is a metal piece below the speaker that needs to be transferred as well.

Otherwise great guild.

I just replaced the keyboard with all those pesky screws. But all is working again. I missed the part in replacing the keyboard itself in the first place. You need to have the sheets in the right order and in the right orientation. Also does it need removal of the stiffening bar that run along the keyboard. I forgot when I removed it, so I was a bit puzzeld when to put it back. Would be nice to add those steps also to this otherwise perfect guide!
