    It looks like you need a Phillips #000 screwdriver for the 10 bottom screws. I tried the #00 and it's too big. Good thing I bought a 23 piece precision screwdriver set or else I would have been screwed.

    scott523 - Contestar

    The 10 screws that hold tha bottom case take a #00 Phillips driver, if yours doesnt fit it's probably because it's cheaply made & not precise enough. The only thing that I needed a #000 driver for was the keyboard screws. They're so small they look like specks of dirt or sand. I stripped out 4 of them & now will need to grind the heads off with a Dremel/rotary tool. The other thing that sucks is iFixit doesn't have a tutorial for keyboard replacement!

    A true Phillips head screw's slots are rounded at their inner corners, to allow the screwdriver to "cam out" (pop out) of the screw head before you apply too much torque and strip the threads in the part that you're torqueing the screw into. However, the screws used in the Macbook don't have those rounded inner corners, so they're not Phillips. Instead, they may be a Japanese standard known as JIS B 1012, or a Frearson (also known as a Reed & Prince), but that's a less common design. Maybe technically these non-Phillips screws should be used with a screwdriver that was specifically designed for them, but they can be properly removed and reinstalled using a truly precision-made Phillips #00 (some people find a #000 sometimes works even better) whose tip comes to a sharp point--not the lousy fake "precision" screwdrivers that are sold in too many places. See my next comment for more.

    johnsawyercjs -

    Many screwdriver manufacturers get away with marketing fake "precision" screwdrivers because, in the words of the Wikipedia article at "Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips #00" or "Torx T5." These sizes do not necessarily describe a particular dimension of the drive shape, but are often arbitrary designations in the same sense as a "Size 8" dress."

    In other words, the quality of many "precision" screwdrivers is poor. In my experience, one of the biggest problems with many fake "precision" Phillips screwdrivers is that the four blades at the tip are often too wide, and their width may even vary on the same screwdriver (they're not supposed to). So just because a screwdriver is marketed as a "precision screwdriver", it may not be, and many that are labeled as #00, or even #000, will not work for a Macbook's screws. See my next comment for still more.

    johnsawyercjs -

    One of the best manufacturers of precision screwdrivers is Wiha ( cost more, but they're worth it. Or buy screwdrivers from iFixit, who seem to be selling JIS screwdrivers.

    Another article with some good info on screw and screwdriver types:

    Also keep in mind that some screws are tougher to remove and reinstall because they have a thread-locking compound on them, which is usually blue.

    johnsawyercjs -

    Phillips #00 is the correct screwdriver for the lower case. Maybe the one you have is worn or badly made.

    David Fear -

    Perfect man!Many thanks!:)

    wertaerte - Contestar

    Compare the short screws carefully before reinstalling them. The shouldered screws go in the holes on the front edge.

    David Kilbridge - Contestar

    thanks twisk, I wish i would have read your tip before I finished putting the bottom of my laptop back together. I managed to get all screws in somehow, but one was in fact too-tight.

    BTW, big big thanks to the Author: Andrew Bookholt. Just used this guide and my trackpad now works again.

    xitxit2 -

    i too need a #000 for the bottom of the case -- i got the recommended screwdriver (#00) and unfortunately it's too big

    plins718 - Contestar

    Before I started removing any screws I took a piece of paper and drew the bottom of the laptop and put a piece of double-sided tape in the spot where each screw goes. That way when I took out the screws, I could put them on the tape so I knew exactly which screw went in which spot. I did the same thing for dismantling the inside on another sheet of paper, then a third sheet for the screen after getting the front glass off.

    mastover - Contestar

    I use a similar technique: I print out the iFixit manual for the job, and Scotch-tape down the screws/brackets/cables I remove at each step next to the component descriptions. That way, when I'm reassembling, the bits are taped right next to the photo of where they came from.

    adlerpe -

    That's exactly what I do for all my repairs! It's the best way to keep track of all of the parts ' original location and to make sure that you don't miss any parts during reassembly.

    joyitsjennie -

    Great idea and one I use often

    Thomas Overstreet -

    Excellent idea! Thanks for sharing it here.

    Laura Sharkey -

    The colours you used for these circles are indistinguishable for colour-blind people. Please consider using something like the palette suggested by visibone:

    Eric Sorenson - Contestar

    Squares, Circles, Triangles (you get the idea) would work as well to distinguish the different screws.

    danzeitlin -

    I'd use a Phillips #000 screwdriver also. The #00 can work, but if the screws are in really tight, it doesn't get far enough down into the screws to get purchase, so it will start to strip (and I agree that the screws are pretty soft). On mine, the screws for the fan were really tight, started to strip with #00, needed a #000 and quite a bit of pressure to get them to move.

    jonathanmorgan - Contestar

    I thought it took a 000 as well. However, I tried both and realized the 00 works best.

    john - Contestar

    Hi i was wondering if you can add 16gb to this model? or is 8 the maximum?

    Igor - Contestar

    The Mid 2010 MacBook Pro 13" does support 16 GB RAM, but it is very picky about the type of RAM. OWC sells a 16 GB kit (2x 8 GB). I think it's got to be 1066 (aka 1067) MHz RAM. A lot of 8 GB modules on the market now are faster than 1066 MHz, and reports I've read say people start getting kernel panics if they use the wrong RAM.

    Some info here:

    "1066 MHz PC3-8500 DDR3 SDRAM"

    "*Originally, both the official and actual maximum RAM was 8 GB. However, as confirmed by site sponsor OWC, if running OS X 10.7.5 or higher, updated with the latest EFI, and equipped with proper specification memory modules, this model can support up to 16 GB of RAM."

    Our Mid 2010 already had "the latest EFI" (i.e. Boot ROM version in System Profiler), so the reference to updating it may not be relevant.

    Winston -

    I used a 00 that fit but the screws were very tight so I used a tiny paintbrush with some wd40 on it and put it around the edges of the screws. Worked like a charm

    valentinedhdh - Contestar

    I had the same problem. The #00 screwdriver worked for some of the screws but some others were too tight and I had to use a #000. Maybe it was because the cover had slightly bent because the battery inside had basically doubled its width, but I still found that the #000 was a much better fit for these screws. Even the ones that came out with the #00 came out much easier with the #000. I would suggest updating this guide to suggest using a #000.

    tarriojuan - Contestar

    Had no idea they were so expensive.

    Franklin - Contestar

    Phillips #00 is the right tool for all the steps (Except the 4 HD T6 screws). Maybe there is dirt in the notch.

    Luis Soto - Contestar

    There is any chance to use the Toshiba MQ01ABD 1 TB 2.5" Internal Hard Drive MQ01ABD100 , it has7200 rpm , shuold it work?

    Luis - Contestar

    If you are running OS X 10.11.2 or newer, battery provided by iFixIt will not work. I've already tried 2 batteries from iFixIt and neither worked. iFixIt needs to come clean on this unfortunate situation. I've already put 8 hours into this futile effort when it should have taken me 45 minutes.

    gkofga - Contestar

    What was your solution? I'm using 10.11.3 OS X. I may need a battery replacement very soon too.

    <i>The 10 screws that hold that bottom case take a #00 Phillips driver, if yours doesn't fit it's probably because it's cheaply made & not precise enough.</I>

    I purchased the IFixIt 54 bit Driver Kit and their Phillips #00 are <b>NOT</b> the appropriate size for the bottom screws on this MacBook Pro. This manual needs to have the tools changed to Phillips #000 Screwdriver. Until then I shall not click the "Give the author +30 points" button. Apart from that, the rest of the manual is very good. It would also be an idea to make a comment about making sure the battery connector is in the correct position when plugging the battery back in. One poster commented that their battery will not charge anymore. My guess is a pin(s) was/were bent due to the connection not being in the vertical orientation when being pressed back together. :-)

    THANK YOU for writing and generously supplying this guide for our use. It is much appreciated. +30 point coming when the Phillips #000 size is changed or added.

    Joseph King - Contestar

    It would be nice to remind fixers which length screws go back in which holes, in case they get mixed up...

    Mike - Contestar

    j’ai remarqué que le 4 vis philips courtes sur le bord avant ont une courte entretoise

    celles des cotés n’en ont pas et sont courtes

    la dernière sur le bord qui comporte les 3 longues, est un poil plus longue

    si l’on ne fait pas attention, les vis des cotés ne peuvent pas se visser à fond et dépassent un peu

    parfait pour le reste ! Merci

    Vincent Morault - Contestar

    I am pretty sure that one of the tools listed as needed has changed from when I looked it up last week and placed the order, and is a mistake. Here is a screen shot of the first step to replacing the fan on my Mac unibody. Doesn’t a 3mm Phillips call for a #1 PH screwdriver? Is the mistake in the size of the screw or the screwdriver designation? And I am sure the last time I looked it did not say I needed to remove 13.5 mm Phillips screws. Maybe I can figure it out, but I once ruined a laptop by dropping a back screw from the screwdriver into the innards. I never found it - until it rattled around and ruined the computer! Should I guess? What does everyone think?

    Where can I buy 5.5 mm tri-wing screw and 13.5 mm tri-wing screw ?

    gansodesoya - Contestar

    I have the same question? Where can you buy new screws. Apple put in these rediculous tri-screws.... The short one went in crooked and jammed. I couldn't get the long one back in at all, not sure why, but it's not catching a single thread.

    My 2nd question is, what the alternative if you can't get the screws back in (e.g. some kind of tape). With only one screw only half way in and jammed, the battery doesn't seem to be moving around, so I think I'm ok, at least for now.

    Mike Mullally -

    similar issue here, I'd like to buy these bolts new. and it would be even better to buy new ones but with a philips head, not a triwing head. please let us know. thanks.

    You can get the tri-wings from ifixit directly - Tri-point Y1 Screwdriver

    or get the whole kit (like I did - it's excellent) - [producto vinculado inexistente o deshabilitado: IF145-072-1]

    i have a triwing y1 and it doesn't work with my battery it seems to be too big, the triwings sold on ifixit are the same when it is written y1 ?

    The Y1-Three wing screwdriver from iFixit is too big!

    sure enough mine has the 5 star torx as well.. this drove me crazy today.....i had to buy a set of 5 stars from amazon....i thought i was losing my mind trying to make the tri wing fit....i finally opened my wife's 2010 macbook pro to find tri wings....then i knew. steve jobs was messing with me from the


    Used a knife and a rubber band to unscrew these.

    dovydas54 - Contestar

    Pentalobe driver for newer Mac laptops worked, not the tri tip.

    joeltbean - Contestar

    These screws do absolutely NOT have the TRI-WING® recess. I find, the LHSTIX 3ULR MicroStix size 3ULR-0 driver fits perfectly.

    unsubstantiated - Contestar

    You're right and there was some inconsistent terminology in the guide. It should be fixed now. The term "tri-wing" doesn't apply here but I believe generic "tri-point" Y0 or Y1 drivers correspond to the Microstix driver you mention.

    Jeff Suovanen -

    A minor improvement, but it would be nice to remind fixers which screw length goes on which side (longer screw on _ side?)

    Mike - Contestar

    Was able to open them using a flathead 1,5mm.

    Just be careful not to damage the screws.

    Olivier - Contestar

    I am answering a 2 year old post but this is for those who may have the same or similar issue in the future.

    When I was putting the battery connector back on that it didn't sit flat against the board before I put pressure on the top of the connecter to press it back into its socket. I then took time to examine the battery connector socket and saw it consisted of long thin vertical pins. I deduced that if the battery connector was not aligned correctly to the pins on the motherboard then it may be very easy to bend one or more of the pins in a way that they wouldn't mate up with the opposing female part on the connector. That sure would cause a battery charging issue. If you feel too much resistance when pressing the connector back into the socket then stop and make sure it is all aligned correctly. I know, not easy with the size, the black connector and black socket. A spudger can be used on the battery side of the connector to raise it to a level position prior to applying pressure to the top of it.

    Joseph King -

    Everything was so easy but that is not the highlight of it all; the replacement parts are cheaper than buying it from a local store here in Taiwan or in The Philippines.

    I put the battery in ok, then placed it on charge and tried to start it. It didn't like this at all, letting out evenly spaced unfamiliar beeps. I felt sure i had done something terrible. I held down the start button and turned it off. Half an hour later I turned it back on, upon which it sprung back to life, much to my relief. The battery needed to be charged before starting it seems.

    ich habe die Batterie wie beschrieben getauscht und kalibriert. Ich komme jedoch nicht über eine Akkulaufzeit von 2 Std hinaus. Womit hängt das zusammen?

    Hi Timo. Please write in English as this is an English-speaking site. That way you will significantly increase the probability of eliciting a response.

    (Servus Timo. Dies ist eine enlischsprachige Website, daher ist es wünschenswert und höflich Nachrichten und Fragen auf Englisch zu stellen. Du erhöhst dadurch ausserdem die Wahrscheinlichkeit, dass dir jemand antwortet.)

    A 2 hour battery runtime is indeed a bit on the low end of what you can expect from a new battery; of course, this will depend on the load and apps that you are running in the background. When you installed the new battery, did you go through the full calibration charge/discharge cycle as described? What is the full charge capacity of your new battery (About this Mac → System Report → Hardware → Power → Charge Information → Full Charge Capacity).

    Hello together. replaced my battery at my macboob pro 13“ mid 2010, had some same issues: battery is not recognized. Not in coconut battery nor in mac os. Seems like it not there. Pushed power button 5 seconds when battery was replaced, also reseted smc via keyboard. Not working. Battery loads more then six hours. Battery status check button on the left side only works when power cable is attached :/ any ideas or something i can do more?

    best regards. Niko

once the battery is replaced with a new one, should it be drained? or charged full?

Myth. Charge it to where think you need the power level to be for "the beach" let's say and then charge it again at your room/in your car if you have the means/the bar with the right adaptor/ hotel lobby/ some hot opposite's room? Wait...

Chappy Jennings -

Apple is currently replacing battery for mid 2009 macbook pro for $129.95 no labor. If you've got a store nearby, not a bad option to get them to do it right and test to make sure battery, and not have to worry about the tiny screws. I've received two different reports however - 1 genius told me they could replace while I wait in about 20 minutes. Another told me I'd have to leave it over night.

John - Contestar

Perfect! I didn't want to wait for the Tri-wing screwdriver to ship, so I gave it a try by wedging a FH 1 in between two of the wings. It worked well to unscrew, but you must be very careful when resetting the screws that hold the battery. If you get them started with your finger (a little pressure with your thumb pushing straight down will get the job done) then you can do a few final turns with the FH 1. If you try to start resetting the screws with the off-center-FH1-workaround, you will strip the screw! Keep the screws centered and don't force anything.

Laurence Benson - Contestar

worked like a charm. my old battery had bulged and made it so that the track pad would not click :-( replacing the battery did the trick.

statprof - Contestar

My local Apple Store wants $179 plus tax to change this battery, AND I have to leave my laptop for "a couple of days." This is one store that clearly doesn't get it (Cherry Creak Mall, Denver). Thus, a DIY fix is mandatory... but, they won't sell just the battery.

channonholiday - Contestar

iFixit sells the battery you need for $119 ([producto vinculado inexistente o deshabilitado: IF163-019-1]), and once you get it, doing the replacement shouldn't take more than 30 minutes, even if you've never done a repair like this before.

Taylor Arnicar -

Rbwham - Contestar

I followed the instruction carefully and the battery works great. However, now my trackpad won't depress in all but the lower right corner. Anyone know how to fix this?

john - Contestar

I found out the battery tab screw holes are slightly misaligned by about 1/2 mm. This causes the battery to wedge in too tightly to the track pad which is directly above. Using a small drill bit I moved the holes slightly allowing the battery to move slightly toward the center of the laptop. This took the pressure off the track pad. Also I took the clear plastic covering off as well. It works great now.

john -

The longer tri-wing bolt won't fit properly into the new battery I got through ifixit. The hole is too small and appears the wrong shape. It seems like this was the case with the old battery too, as there a crack in the corner near the hole where someone had to widen it. In the end I used the tip of a metal knitting needle (the sturdiest thing of the right size I had to hand) to widen the hole slightly, causing a similar crack. I guess since the bolt's thread is only at the tip where it enters the metal laptop casing this shouldn't affect how securely the battery is joined.

I had no joy with a 00 Phillips either, but this was probably due to the crappy quality of my socket set.

Christopher Rempel - Contestar

If you buy this battery new from OWC (macsales), they include--for free--the two screwdrivers you will need. Got this battery today for 99.00, installed it myself based on this instructional in 10 minutes. And I have never opened a macbook before, first time. The main things: don't lose the screws, most of them are incredibly tiny (I lost one when dusting with microfiber), don't forget to put the screws back on battery housing, and be gentle and patient when removing small, semi-rigid battery wire cable. Best wishes.

Chase W - Contestar

Soham Shah - Contestar

I bought a new battery from, was around 100€. I have to say I'm a bit dissapointed, charge is nowhere near full it's around 3500, battery barely manages an hour and a half. Have to say it was not worth it. Cocconut battery says it's 3,1 years old and lost around 20-25% of it's original capacity. I feel I got robbed for 100€

Mario Markovic - Contestar

Thank you SO much.

This was easy and worked very well.

I used a battery from Duracell Direct, which cost £50 (inc. delivery) which has a one year warranty.

I took the opportunity of cleaning the inside while it was open, using a soft sable-hair paintbrush, to lift the dust off the circuit board, and a microfibre cloth on the inside of the case.

It read 46% charge when first put in , (which may not be correct until it has calibrated itself) which dropped on use to 18%, and has recharged happily and just now it has reached 100% - brilliant!

Thanks again,

replaced optical drive with 250GB SSD.

replaced 2x2GB RAM with 2x4GB.

replaced old battery..

Things work, except the fan never slows down and makes a lot of noise.

The fan start at full speed as soon as I click the power button, even before the screen lights up.

Please help.

Also the bluetooth and camera stopped working :(

The step by step works precisely. I see improvements in speed and holding a charge. Thanks W Galan and 7 other contributors.

Echo Sierra - Contestar

Decided to hold off on replacing the track pad until I had successfully replaced the battery first (my first project). I didn’t realize my trackpad not working could be because of battery swelling, but I’m pretty sure that is what happened. My gratitude is overflowing. And I can use my trackpad again. :)


Andrew Olsen - Contestar

Any tips on what to do with an old battery? Landfill? Recycle it… somewhere?

Andrew Olsen -

@abolsen It should absolutely get recycled! You can’t just drop it in the bin though. You can find some guidance on finding a recycler here. Depending on where you live, you may also be able to take it to big box store as a lot of them freely accept batteries for recycling (OfficeMax, Staples, Best Buy, etc.).

Jeff Suovanen -

Amedeo Cogliati - Contestar

Excellent instructions! May want to add that until the replaced battery has charged, the operating system may throttle the CPU speed. Among other things, this can lengthen the time to boot considerably.

The holes on the battery for the battery mounting screws may not line up exactly with the threaded receptacles on the MacBook chassis. You may have to exert some pressure on end of the battery to get the holes to line up. Recommend installing the longer screw (adjacent to the memory chip) first.

Worked like a charm! Took a little more than 5 mins, but who’s counting? My old battery had more than 3,300 days on it and although it still worked fine, after almost 10 years of service, probably better to go ahead and replace it. Thanks for the instructions!

I changed the battery, the HDD to a SSD and the RAM from 2GB to 6GB (or 8, can't remember). When I try CMD + R it doesn't go into OS recovery. When going into diagnostics (holding D when booting) and start the hardware test it gives me a error code: ‘4SNS/1/40000000:TB3T-128.000’.

When Googling this error I find that this is a system sensor for the battery temperature that is not working. Did I buy a broken battery? Please help!

Piece of cake. Thank you for the terrific instructions and parts. The battery replacement was quick and easy and my computer runs great. I thought that I was going to have to replace the trackpad, but the swelled battery must have been interferring with it. It works great now.

Merci beaucoup pour toutes les explications, j’ai réussi à changer ma batterie sans aucun souci. J’espère que le prochain tuyo sera de comment nettoyer l’ordinateur à l’intériorité car quand j’ai l’ouvert, il était plain de poussière. Donc, j’ai rien touché, seulement la batterie. Je suis contente. merciiiiiii infiniment.

Have spent over an hour trying to get the long trip tip screw to seat and screw in

Tried screwing in the short one first and that didn’t work.

Any advice? will the battery stay put if we don’t use this screw?

Now after over 2 hours of trying to screw in the long tri tip screw which holds the battery, I decided to put the old battery in place to see how it screwed in. IT WENT RIGHT IN!!!. So eyeballing some more, we can see that the plastic screw hole on new battery DOES NOT LINE UP with that screw hold. Comparing the new and old battery back to back they appear exactly the same size etc, but obviously not. The old battery will lay right over the screw hold (without securing the battery under the 3 cover tabs) but the new battery hits on the side and top when trying to lay it down directly on top of the screw hole.

My question now is, can I secure the new battery with just the short tri head screw or is that absolutely a no no. Thank you anyone in advance for advice, suggestion, answer.
