    How much weight can I save by removing the optical drive?

    gunes314 - Contestar

    You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.

    Tip: Use one of those weekday pill holders to have a cheep way to store screws you remove and each day of the week can be for different sizes or parts. It has been handy to have (much less expensive than the magnetic mat.

    Robert Wacker - Contestar

    Hello, where can I buy the screws I need in case I lose one of them?

    taylornya - Contestar

    I have one stripped screw... How opening without drill it?! Any suggestions please?

    rodrigosady - Contestar

    I also stripped a couple screws. I wasn’t able to open it up without drilling. After drilling the heads and removing the cover it was easy to hacksaw the tip and unscrew with a standard driver.

    Michael Wilkens -

    My top tip - make sure you buy good quality Phillips screwdrivers and a magnetic holder. Cheap screwdrivers won’t get the screws undone safely. Without a magnetic holder you have no chance of getting the tiny crews in and out safely.

    jeremyyoung - Contestar

    A good Phillips 00 is your friend here. Also, when reinserting the screws, gently start anticlockwise and you wil feel a click at the start of the thread. This tells you you’re in the right place and less likely to cross-thread through force in the wrong place.

    Iain Boyd - Contestar

    I feel like these are 000 screws. Amazon sales describe them as such and my 000 screwdriver fits better

    Before ordering a new Trackpad remove the existing battery and try clicking the Trackpad. If it clicks OK with the battery out the source of problem is likely a swollen battery, which should to be replaced even if it still works to some degree. From the side of the battery you will likely see the soft part of the battery bulging beyond the hard case.

    Patrick Langvardt - Contestar

    That’s absolutely correct as I can testify. With the battery removed I also adjusted the T6 set screw that adjusts the sensitivity of the trackpad click, evidently someone had cranked mine down tighter than the factory setting.

    Le quatrième paragraphe dans les instructions en français n’est pas correct : ce ne sont pas les 2 petites vis, mais les 7 petites vis qui sont inclinées. Et les 3 grandes sont bien verticales.

    Bonjour ! Merci de votre observation. J’ai corrigé la traduction. iFixit étant un wiki, n’hésitez pas à modifiez si vous remarquez une erreur :) Encore merci de votre attention et à bientôt !

    Tip: if you have a magnetic screw mat or similar, lay the macbook over the mat to make sure it catches any screws that may decide to fall of and hide under your table

    • Usa tus dedos a modo de palanca para levantar la tapa inferior del cuerpo del MacBook por la zona del ventilador.

    • Extrae la tapa inferior.

    • Usa el borde de un spudger para levantar el conector de la batería haciendo palanca para extraer su toma de corriente de la placa madre.

    • Se recomienda hacer palanca en los laterales del conector para extraerlo de su toma de corriente. Ten cuidado con las esquinas de los conectores ya que pueden romperse con facilidad.

    Is this step of removing the battery connector required?

    manodh - Contestar

    yes - as with disassembly of any electronic component you have to remove any power source. You don't want to accidentally turn the Mac on

    khull -

    Prying the battery connector off does not take much force. I did exactly what the guide suggested (walked it off back and forth) with the spudger without any problems. Just be very gentle, much like with anything inside laptops, they are very fragile and need to be worked with carefully. A+ instructions, battery replacement was a success.

    aekinaka - Contestar

    Be patient on disconnecting this one. It worked for me step by step, little by little.

    Phil Wagner - Contestar

    I used the nails of thumb and pointer finger simultaneously - worked pretty fine

    Reinhard Kaune - Contestar

    • Dobla el cabre de la batería ligeramente para alejarlo de su conexión en la placa madre para evitar que se conecte accidentalmente mientras trabajas.

    I put some tape between the connector and socket while working on the drive.

    Stephen Smith - Contestar

    That's a good tip

    Anrothan -

    Great tip, I did that too

    Ahmed Mahran -

    One other note: The screw heads fit flush with the curvature of the case -- which means that they aren't exactly horizontal. In other words, they aren't perpendicular to the table that the computer is resting on. Don't try to force them straight in vertically, because you'll risk cross-threading them. (nearly ruined one screw hole myself!)

    lelandjordon - Contestar

    On my MacBook Pro, the connector seems to be an integral part of the battery.

    Jerry South - Contestar

    I suspect it’s just like the special screwdriver required for seatbelts on cars – to discourage regular consumers from attempting repairs. Of course, this only encourages consumers to use the wrong tool to attempt to repairs

    • Remueve los siguientes dos tornillos:

    • Un tornillo Tri-punto de 5.6 mm.

    • Un tornillo Tri-punto de 13 mm.

    Something isn’t right here. On my MacBook Pro, the connector is an integral part of the battery.

    Jerry South - Contestar

    Verify that this is the correct guide for your specific model—if not, we’ve got guides for all the other models, too.

    Jeff Suovanen -

    And which Apple “Genius” decided that a tri-wing screw would be just perfect for the job of holding the batter in place? Not smart for a genius.

    Jerry South - Contestar

    These tri-point screws are Y0 size. You’re welcome :)

    Rossi Macri - Contestar

    The 13 mm Tri-point screw was very tricky to screw back into place. I had to make several attempts, unscrewing and realigning the battery to get it right. The rest of this fix was very easy, but this one screw was the hardest part.

    Raymond Rinaldi - Contestar

    As per Rossi Macri’s comment, I also observed for step 5 that both screws are Tri-point Y0 for my MacBook Pro 13 inch mid-2012 model.

    • Con cuidado remueve la etiqueta de aviso de la batería de la caja superior entre la batería y la unidad óptica.

    • No remuevas la etiqueta de la batería.

    What is the reasoning behind not removing the label from the (old) battery?

    tom - Contestar

    Probably to help you remove it? Not sure, but I used it along with the clear tab to pull the battery out. Worked pretty good.

    aitorrecalde -

    One of the main thing is that it can weaken an already old battery which is never a good thing, especially if people try to remove the label using a pointy device and piercing the battery (can explode !). Also it is not useful to remove it and it allow tracking of old parts (recycle, dispose, …).

    • Utiliza la lengüeta de plástico adjunta para remover la batería de la caja superior.

    • Si estás instalando una batería nueva, debes calibrarla luego de la instalación.

    • Cárgala hasta el 100% y luego sigue cargándola durante al menos 2 horas más. Luego, desenchúfala y úsala normalmente para drenar la batería. Cuando veas la advertencia de batería baja, guarda tu trabajo y mantén tu laptop encendida hasta que se duerma. Espera al menos 5 horas, luego cárgala de forma ininterrumpida hasta 100%.

    • Si observas alguna conducta inusual o algún problema luego de instalar tu batería nueva, podrías tener que reiniciar la SMC de tu MacBook

    My replacement battery came with a clear protective film that should be removed before installation. Be sure not to overlook the film on the bottom of the battery as it covers only a portion of that side and might be easy to overlook.

    Do not over-tighten the bolts holding the battery in place. One of the tabs on the original battery was broken, presumably due to over-tightening.

    Patrick Langvardt - Contestar

    The calibration suggestion given in this guide differs a bit from what iFIXIT sent with the battery. What came with the battery went like this…

    For optimal performance, calibrate your newly installed battery. Drain battery below 10%, then charge it uninterrupted to 100%.

    Daniel Lavelle - Contestar

    I recommend disregarding those instructions and following the steps in this article:

    1. Charge it to 100%, and keep charging it for at least two more hours.

    2. Unplug your laptop and use it normally to drain the battery.

    3. Save your work when you see the low battery warning.

    4. Keep your laptop on until it goes to sleep due to low battery.

    5. Wait at least five hours, then charge your laptop uninterrupted to 100%.

    Sam Omiotek -

    would it be dangerous to use the macbook without a battery in the meantime?

    724 F - Contestar

    It’s not dangerous (assuming you have put the back cover back on), though the computer will run slower. The charging assembly cannot supply as much amperage as the battery, so the processor will be throttled.

Many thanks to Phillip and the other contributors who put this guide together. My late 2011 MacBook Battery was headed downhill fast. Having used IFixit before, I headed back to the site and found the parts and help that I needed. My new battery arrived two days after placing the order and I went to work. Everything went smooth as silk(again thanks to some IFixit tools, etc.)and I was up and running in no time. Thanks for this great site and for encouraging do-it-yourself repairs with great guides. Hooray to all who like to fix things and boo to manufacturer who design products that make this difficult. Cheers and keep up the great work. Lowell Allen, May 26.

Thanks a lot, was great help and needed this greatly for one of my macbook.

Best regards from,

Handyman Dream - Contestar

Replacing the original battery was easy, but the replacement battery loses a charge very fast.

20 minutes, I’ve lost 11% charge.

Alex - Contestar

Thx a lot to everyone at iFixit, now my MacBook Pro Unibody Late 2011 can take a second breath

Franck Bourgeois - Contestar

Thanks for the easy to follow instructions! My battery install kit did not come with a spudger, so I used a plastic knife and my finger nails. I was careful to make sure the little seated edges didn’t break off (that’s when I transitioned to my nails).

Christi Ruby - Contestar

Having never done this before it was remarkably easy to do following the very clear instructions., the tool kit I ordered that came with the battery was perfect so pleased I ordered that as well. I was warned it would take up to 2 weeks to deliver to UK from Stuttgart but they shipped it right away and arrived with Fedex within a week, great service!

Tip.I made a diagram on a piece of paper of where all the different screws went and laid them on the paper so was easy to replace them in the right place.

Feel so good I have saved a visit to the computer repair shop, thank you so much :))))

Lesley - Contestar

Great guide. Excellent written instructions. I upgraded my mid-2012 MacBook Pro 13 inch two years ago with 2-8 GB sticks for a total of 16 GB, a replacement battery and a new 1T SSD hard drive and it is still going strong. I just pulled this guide out again and updated a friend’s computer. She’s so happy with the speed and performance improvements! I had no issues with any of the hardware swapping and was even able to restore here touchpad to working order by blowing out the dust and debris when we were in doing the upgrades. I love I-Fix-It!

Julie Garbutt - Contestar

I’m super impressed that I’m able to keep my old MacBook Pro going, despite it being older than my oldest child! The old battery was on it’s last legs, with about 30-45 min per charge, meaning I was having to more or less use mains power the whole time. Fitting a new battery was a little nerve-wracking, but really easy and I managed to do it really quickly - so fast that I’d ordered a Domino’s before I started and was done well before it was delivered! 😂 I picked up a genuine replacement battery from eBay for less than half the price on iFixit though, and it came with the required screwdrivers. I just used a couple of pen lids to pry the battery connector off. Thanks for the guide. 👍
