Use this guide to remove or replace the heat sink.

Don't forget to follow our thermal paste application guide after you have removed your heat sink.

  • Remove the following ten screws securing the lower case to the upper case:

    • Two 2.3 mm Pentalobe screws

    • Eight 3.0 mm Pentalobe screws

For all the screws you use the P5 pentalobe screwdriver?

Pentalobe is only for the screws on the bottom cover. The Torx screw driver is for the remainder.

hello -

Is the Pentalobe screwdriver mentioned in the tools list? I did not have one so I used a filed down flat blade screwdriver. Not a fantastic idea, but it works.

Yes, it's mentioned on the top of this page. P5 Pentalobe to be precise. I didn't have one either, so I bought one from iFixit and that works fantastic. An absolutely precise fit, which is important especially when you might open your MacBook a couple of times during the years you own it. Not using the correct tool might do more harm to the screws than you want! I once had this with a Lenovo Yoga 3 Pro, which has Torx screws (T4 I think) and I used cheap Chinese quality tools, with the result that both the tool and one of the screws are damaged.

the macbook in the picture is 2012. does it has the same structure as 2013?

I never, ever, ever considered using anything but the correct tool on the Pentalobe screws. Too easy to strip and void your warranty (if still in effect), as well as make it almost impossible to get inside later for another upgrade or repair. The Wiha P5 Pentalobe screwdriver fits like a glove and costs only about $11 (a fraction of your drive's price)at Amazon.com. Get it!

There are two screws that are shorter-they go to the back near the vent.

This was already mentioned at the start, it says 2x 2.3mm screws and those are coloured red instead of orange for the other ones in iFixit's image.

  • Use the flat end of a spudger to lift the battery connector straight up out of its socket on the logic board.

I have a friends MacBook Pro that has some water damage that caused the MacBook not to be able to use battery power, but still work when plugged into A/C. Upon further inspection I can see visible corrosion on a few of the 9 cables going from the battery connector to that small circuit board. Is it possible to just replace that circuit board?

I have the some problem. I was thinking to replace the whole battery but I am not it will solve the problem. Any suggestions?

Sometimes it can be enough to just clean the contacts without having to replace the entire board. Dosent work for complicated IC's like plcc type, where corrosion is underneath the chip. Here you will have to reheat and reapply the IC.

Have either of you replaced the battery and/or circuit board to fix the MacBooks with the water damage ? I have the same problem with the MacBook working fine when connected to power but dying immediately when the power cord is removed.

Hi, Steve. I had the same problem: Macbook Pro 15 retina with coffee damage. And it worked fine when connected to power. I made it working after replacing the whole battery. It seems that circuit connected to the battery becomes disabled to prevent short circuit.

When placing the battery connector back into the socket on the logic board, check that every part of connector is pressed down. You should hear a soft click when it's back in place.

  • Bend the battery connector up out of the way to prevent accidental contact with its socket during your repair.

If you miss or let this step for later like I did, the power left in the battery even though the computer is completely shut down, will screw up the I/O board cable like I did. I noticed this after I put all the pieces back, turn the computer on and surprise, no wifi hardware is detected. -.-
