Use this guide to replace a broken or noisy left fan in your MacBook Pro 15" Retina Display Mid 2015.

Note that the left fan is on the left of the machine while you're using it, and on the right while you're working on it.

Remove the following pentalobe screws securing the lower case to the MacBook Pro:

    • Eight 3.1 mm

    • Two 2.3 mm

The number of screws listed here is wrong on my model. I had four of the smaller size.

Just to add to my comment above (I can't edit it because it's anonymous), my MacBook Pro is a mid-2015 15in model 2.8GHz (A1398; EMC2881). For the bottom case it uses six 3.1mm screws, and four 2.3mm screws at the clutch/hinge side of the MacBook Pro. I tried using a 3.1mm screw at the clutch/hinge end, as described in the main article, and they don't fit. It has to be four 2.3mm screws.

Removing the screw will void warranty?

Test Application - Reply

Ok, so here is what I discovered. There is no mobile application for these instructions, while having them on a computer is nice but when the computer you have is the one you are changing the battery on these instruction are of no use. I advise coping them and then paste them in PDF and print them out. Or you better have a photographic memory. I’m just saying.

Lifting from the edge nearest the clutch cover, lift the lower case off the MacBook Pro.

  • The lower case has two plastic pegs (red) that fit into plastic clips in the upper case (orange).

  • During reassembly, gently push down the center of the lower case to reattach the case to its two plastic clips.

pretty hard to put it back, so I just remove the clips on the upper case....

The trick to putting it back on is to guide your fingers to the same level as the clips, and then when you put the case down move your hand from the left side of the case to the right side of the case; applying pressure when you reach the area where the clips are.

  • Peel back the sticker covering the battery connector.

You only need to remove the tape to the edge of the flap. This is enough to be able to pry the battery connector up.

  • Gently lift each side of the battery connector to pry the connector out of its socket on the logic board.

  • Bend the connector back toward the battery, ensuring that the battery connector doesn't accidentally make contact with the logic board.

why is this necessary to remove a hard drive?

@lawrencetaylor On any electronics repair, you need to disconnect all sources of power before you start. It’s a basic safety precaution and also removes the risk of accidentally shorting a connection somewhere (which can potentially kill your MacBook).

  • Peel the left rubber cover up off the fan and fold it out of the way.

  • Remove the following three screws securing the left fan to the logic board:

    • One 3.6 mm T5 Torx screw with a wide head

    • One 5.0 mm T5 Torx screw with a 2.0 mm long shoulder

    • One 4.4 mm T5 Torx screw

  • Use the tip of a spudger to flip up the retaining flap on the left fan ribbon cable ZIF socket.

  • Be sure you are prying up on the hinged retaining flap, not the socket itself.

  • Lift the fan and push it gently towards the back edge of the MacBook to free the fan cable from its socket.

    • The fan cable may be adhered to the logic board—to avoid tearing the cable, gently peel it up while lifting the fan.

  • Remove the fan.
