Ôtez les dix vis suivantes, qui fixent le boîtier inférieur au boîtier supérieur :
-
Deux vis Pentalobe P5 de 2,3 mm
-
Huit vis Pentalobe P5 de 3,0 mm

-
-
Glissez vos doigts entre le boîtier inférieur et le boîtier supérieur.
-
Séparez avec précaution les deux boîtiers, soulevez et retirez le boîtier inférieur.
To reattach bottom case I found it helpful to line fingers up with clips under case should snap easily
If your old battery has swollen, the lower case may “pop” open. Don’t lose your screws!

I took my pointer and thumb (which are luckily long enough) to feel where the studs are on the back panel, and then as I put the back panel back on, I pushed in the spot I had marked with my fingers to ensure I was applying pressure only on this part.
If you’re doing an iFixIt battery replacement, the replacement battery has two rubber nubs which are right where the clips are that receive these studs. Folks have been saying it’s hard to get the studs to clip back in after replacement, and I had the same issue. I trimmed the top of these rubber nubs, which are a bit bigger than those on the original battery, with some side cutters. That made the fit much better.

A plastic foam cover also covers plug and socket and the whole battery. It is easy to remove it from the right side to the trackpad wire that the battery plug is free like shown in the picture. I kept it to use it again later.
I have done tons of these battery replacements.
You don’t need to do anything on the list after you disconnect the battery, apart from carefully moving the speakers out of the way, and then prise up the battery modules. I just very carefully, and with little even motions, use a large slot screwdriver. Being careful to keep it flat, to not puncture the battery.
Easy peasy. I have never had an issue after dozens of the tasks…
Dear Sir,
as you seem to be very much experienced with battery replacements you might perhaps give me a hint why after having removed the battery pack successfilly, the keyboard doesn't work anymore after booting the system. The Touchpad works, the keyboard backlight works but typing does not function at all.
I only disconnected the battery connector and touched nothing else. I am quite desperate …
I agree with Dave la Rose, provided you use heat rather than solvent to remove the old battery (or possibly floss, haven’t done that). Please see my comment further down this thread on how to use an iOpener for correctly heating the glue joint
After removing battery contact board plastic. My screwdriver accidentally fell and touched the battery board. And it short circuited. Now my battery doesn't charge. My laptop doesn't work without charger now. shuts after a few minutes of use. Can i fix it without sending it for repairs?
Is replacing the battery necessary?

Avec l'extrémité plate d'une spatule (spudger), tirez le connecteur de la batterie tout droit hors de sa prise sur la carte mère.
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?
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.
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.

I thought I made sure it was connected but when running the computer it only detected the battery but couldn’t power it. I had to run with power adapter. Also it didn’t charge. I guess some pins were connected but not all. To verify that all were connected I removed the plastic cover, placed it carefully completely flat, and then reattached the plastic cover. After that it worked!
Lift from the long, flat side, not the shorter side. In this picture, you should lift from the NORTH part of the connector, not the WEST side like they are doing. This is because you can spread the pressure from lifting the connector across more area, as compared to the side. I accidentally broke off part of my battery connector lifting it up the way shown, but was able to do it the way I described without problem. Make sure to lift from the wide part so you don’t have my same trouble!
The connector is no more than 1mm thick… the socket is 3-to-4mm deep so make sure you’re trying to remove the connector itself, and not pulling at the socket.
You can do it from the side like the picture, but i would recommend twisting almost like a screw driver once you have leverage under the overhanging part of the left side like in the picture. Twist the tool so that it starts to put pressure on the top, until you’ll hear it click out. You can be somewhat forceful but it shouldn’t require a lot of strength. Guiding the tool with one hand and twisting with the other is a good way to attempt this.
After I put the battery back I found out at this step that the new battery connector was off by 2 mm (because I installed my battery slightly off). Since the connector is rigid, I removed it’s plastic cover (just like we all did in Step 4) to free the cable, which allowed me to bent it enough to properly plug the connector.
Simple question: why we need to do this, I mean, disconnect battery from main board?
Well, I’m reading this step in the battery replacement repair guide, so it’s pretty critical to disconnect the battery from the main board. I’m guessing these steps are reused in other guides where disconnecting the battery might not be such an obvious need.

Also wondering the same. I came here from a link to replace the fan. Is it necessary to disconnect the battery inorder to replace the fan?
The connector wires from the battery to the connector are long
You'll have to bend them downward and into the small cove that exists so the connector can fit in place.
So use the a plastic card or flat end of the spudger to bend them downward and folded a bit back so the connector will fit in place.
Use your old battery as a guide for how they should be bent.Hi All ,
I followed the instructions step by step and changed the board successfully and reconnected everything back. When I powered it back on I can see it is charging again however it just displays a black screen and no display. Keyboard light comes on as well and the apple logo light on the back lid also turns on. Not sure what is wrong ? It has been charging for more than 15 minutes and still no joy. Anyone able to help solve or identify the issue .
Thanks
The connector cover is slightly wider and longer than the socket (<1mm) so there is a small "lip" around the top that can be used to lift it.
If your are not familiar with those repairs, and as with most of those connections, I recommend to take the time to observe your computer and the pictures from the tutorial, reading instructions and comments before starting each step. This battery connector needs both a bit of force and of precision. For a battery repair the connection of the new battery is a bit more tricky, you need to have your battery in the right position and to force it a bit the connector

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. -.-
@sebasgaes, shoot, I'm only part way through the process, but I skipped this step thinking it wasn't necessary. I'm only through step 12 right now, but is there a fix if my machine doesn't recognize the wifi hardware after I've put it all back together? I don't see reference to the "I/O board cable" anywhere else in the instructions, so I'm confused about your mention of that...
UPDATE: I completed the job, rebooted, and all is well, wifi and all. Thanks anyway; gotta love iFixIt!!

Passez le bout de la spatule (spduger) en dessous de chaque câble d'antennes afin de les déconnecter de la carte AirPort.
-
Connectez le câble avec le long manchon au connecteur du milieu.
-
Connectez le câble avec le petit manchon à côté de la vis.
-
Le câble restant n'a pas de manchon et se connecte sur le connecteur restant, c'est à dire celui à côté du ventilateur.
Please tell me what each antenna is responsible for? J0,J1,J2 I have problems with bluetooth and I would like to know which of the connectors is responsible for this?
well，i was going through the same problems，and it was like all of sudden they were broken. by the way, have you find something now?

Is this responsible for wifi? I re-did my screen and fixed it from blackening, but the wifi icon says "Wi-Fi: No hardware installed". Is this part responsible? If I replace it will I get wifi back?
I am having the same exact problem as described by Phil - 04/25/2017
I replaced the card but the wifi and bluetooth keeps disabling itself after few minutes of use , only reboot reactivate it.
I am thinking of changing the antenna ? any ideas? suggestion ?
your help will be very much appreciated .
This isn’t the solution you are looking for, but what I did to my 2015 mbp when the wifi card started failing was getting an external wifi adapter. It’s cheaper, small enough, and works. I got this type: https://www.tp-link.com/us/support/downl... but any type works, this one is just small enough to be unassuming.
Hi peeps,
I have a wifi problem on this MBP 13” early 2015 and was pleasently surprised to find your guide to changing the airport card.
However upon closer inspection it seems that on my MBP (purchased new or so I thought) the 3 antennae seem so have been soldered together at the point where they are clamped to the chassis. I have photos but cannot post here. Can anyone conform that where the 3 antennae wires are held to the chssis by the 2 scew metal support (just before disappearing into the screen hinge), the support is not meant to short the 3 wires together. This makes no sense for 3 seperate antennae wires.
Any advice /close up photos is welcome here.

I have mac pro 13” 2015 late model, I'm having similar wifi connectivity issue, I have tried all troubleshooting like nvram ,svc and all finally removed airport from I/o board and put it back however it didn't solved the wifi issue. Sometimes wifi connect sometimes not, when ther’s no wifi I used to restart the system but it's not working all the time.
Any idea what's the real problem , do I have to replace airport , will that solve the issue?
I received one of these MacBook Pros with the left wire completely frayed and detached! No display signal on the internal display whatsoever. Is the problem because of this wire not being attached, or is it elsewhere? I get an external display signal without issue. I tried restoring the original OS, same problem. Display System Preferences can’t detect it. The LVDI cable on the other side is fine. One other thing is, all the screws are the same short length holding the bottom case. Someone reassembled this machine and lost the screws!
For all the screws you use the P5 pentalobe screwdriver?
Carlos - Réponse
Pentalobe is only for the screws on the bottom cover. The Torx screw driver is for the remainder.
Fredrik -
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!

I followed this exactly and was able to replace my broken trackpad. I did not have to replace the ribbon OR the battery. However I would suggest getting the ribbon since it’s fairly cheap, as for the batteries I was able to do it with a card only. I didn’t use any heat or the liquid but it takes some time. You really have to work the card in there to release the glue. Also you must be very careful not to bend the batteries or damage them, if you do you must replace with new. This took me about 1.5hrs and my computer works like new. Apple cost for this job was around $450, I did it for $120. Big ups to ifixit for this awesome tutorial, tool set and parts!
On a side note, only use quality tools, the cheap ones will break or strip the screws.

Note that the eight 3mm screws have a shoulder under the head, while the two 2.3mm screws are “full thread”, i.e., there is no shoulder under their heads. It’s important to put the two screws with no shoulder at the hinge of the cover.
All ten screws require a P5 Pentalobe screwdriver, preferably with a magnetized tip to help hold and position the screw.
All of the screws have blue “Loctite” thread locker compound on their threads. This is to help prevent the screws from working loose and falling out. Don’t attempt to clean the Loctite from the screws — leave it in place, and it will continue to help prevent the re-inserted screws from working loose.
When replacing the bottom cover, it is a good technique to insert and BEGIN tightening all ten screws BEFORE fully tightening any one screw. After all the screws have been started, then go around and finish tightening all of them. By doing this, you make it easier to feel that each screw has been started properly, and is not “cross-threaded”.

This is what I found on my MBP mid-2014 13” Retina. All 10 used the same screwdriver. I didn’t see the blue “loctite” but I also got my computer refurbished.
Evan Shulman -
A good technique for starting to thread the screws when replacing them is to position and align the screw, and with the driver, gently turn the screw in the REMOVAL direction until you feel and hear a slight click. This click happens when the leading thread of the screw drops off of the leading edge of the thread in the hole — this is the point at which the threads are properly positioned for engagement. You can now turn the driver and screw in the TIGHTENING direction. This technique will help prevent accidental “cross-threading” of the screw, which will damage the threads permanently.
Note that this is a useful technique when installing ANY threaded fastener.

Tip: Use post-it notes to keep track of screws
1. Pack of post it notes
2. Stick screws to the sticky part of the post it note
3. Write on the post it note which step and what kind of screw it is

Hi, in order to drain the battery I am running:
yes > /dev/null
in 4 terminals, so the CPU maxes out at almost 99%.
I hope this speeds up the battery draining process.
And the backlight is at maximum brightness :-)
You can see the cpu load in Activity Monitor.
Its draining at 20% per 15 minutes.
Any concerns about draining the battery in this way?

Something I’ve been curious about, is it possible to upgrade a late 2013 Retina model MacBook Pro, with the improved 16gb ram and i7 processor logic board from the 2015 retina model? I’d be interested to try but not ready to shell out the $500+ to be the first lol

Without rehashing what others have said, I would highly recommend reading through the steps *and* the comments for each before tackling your replacement for tips. Highlights for me were: only disconnecting what actually needed to be disconnected, rotating the spudger to release the track pad cable, a hair dryer worked perfectly fine, and the pencil outline of the battery before you remove. You got this!

I use replaced SSD and it was super easy and working great. I can finally upgrade Mac OS with plenty of room to spare and no more low memory alerts. Well worth investment and didn’t have to buy new laptop

It's interesting that this tutorial is rated Moderate even though you need to remove the battery. The battery removal tutorial which is basically the same but with fewer steps is rated Difficult.

when i pulled the screws out i arranged them in the same way they were in. the top 2 middle screws appeared to be shorter than the rest. in order to keep them in place i got a square of packing tape sticky side up, taped both sides down with 2 other pieces of tape. and then put the screws head down in the order i pulled them.

Excellent instructions although checking battery and speakers aligned before fixing batteries into place is essential. MacBook good as new!

I find it helpful to spread a soft, slightly fuzzy cloth (like flannel) over my workspace before doing something with small parts. It keeps screws and things from rolling or bouncing away. A towel might be too plush, though, as a screw might get lost in it.

I cannot get the two screws (that are different than the other ones) out and now they’re stripped. Any idea what to do without using a drill?

DO NOT REMOVE SPEAKER CABLES!! The connectors are fragile. Just remove speakers and bend attached cable away from battery. Same for trackpad cable connector at front side. This cable crosses the middle of the battery. Just remove the one connector on the back side - leave front side connector attached and fold cable toward front of computer out of way of battery.
