はじめに

このガイドを参照して、MacBook Air 11インチ Mid 2012のバッテリーを交換しましょう。

注意:薄いプラスチック製フィルムが交換するバッテリーに貼られている場合、剥がそうとしないでください。それは糊付けされていて、MacBook内部にある限りバッテリーパックを保護しています。

    • まず、コンピューターをシャットダウンし、柔らかい素材の表面上に天面を下にして置きます。

    • 以下の10本のネジを外します:

    • 星型ネジ 8mm 2本

    • 星型ネジ 2.5mm 8本

    • 星型ネジを外す際に必要な特別ドライバーはこちらで購入できます。

    When you say:

    Remove the following ten screws:

    Two 8 mm 5-point Pentalobe screws

    Eight 2.5 mm 5-point Pentalobe screws

    Do the 8mm & 2.5mm dimensions refer to the LENGTH of those screws, or the size of the pentalobe? That is, are there other sizes of pentalobe drivers like there are for hex, phillips and torx? When only one dimension is provided, it is usually the socket/driver size, not the screw length, maybe since the length cannot be seen when the screw is installed.

    Can I suggest that you clarify your instructions so folks are confident they are only in need of _one_ pentalobe driver?

    Nerdily yours,

    Larry (whose iPhone 4S can now get through a day without 6 recharges thanks to ifixit.com ;-)

    The 8mm and 2.5mm are the length of the screws. One pentalobe P5 screwdriver suffices for all the screws (P5 is implicitly the size of the pentalobe screw heads).

    I sourced all the parts from ifixit, plus a magnetic project mat which I found to be very useful for organising the teardown and reassembly.

    Keep the 2.5mm tiny screws away from the MagSafe connector as they will be attracted and sucked in to the magnet.

    I performed this on my MacBook Air (11-inch, Mid 2011), model A1370. Rather than using the spudger to un-attach the batter connector, I gripped either side with my fingers as the second photographs indicated, and gently pry/wiggled it up and out by initially pinching into the side gap with my finger nails. The reason I did it this way is that the spudger works by leverage and I was afraid to rest it against the components surrounding the connector. The photos and instructions are excellent and illustrate the maneuver perfectly.

    Hello there... In my case by battery exploded.... Can I still try to change it using these instructions?

    Fabio Matos - 返信

    The instruction to lift the edges of battery connector before disconnecting is certainly not clear. In my case, the cconnector pins came off the board with the battery, requiring further costly repairs. I would suggest that this instruction be more specific and include a caution.

    Deirdre Rogan - 返信

    It worked fine for me, but as others mentioned, you need to be careful to remove the battery connector from the motherboard connector and not accidentally remove the motherboard connector from the motherboard itself.

    Additionally, on reassembly, I found that quit a bit of pressure was needed to get the new battery's connector to snap in place. More than I was comfortable applying, but it was necessary and it worked without a problem.

  4. バッテリーを外すためには、以下の5本のネジを外します:

    • T5 トルクスネジ 5.2mm 2本

    • T5 トルクスネジ 6mm 1本

    • T5 トルクスネジ 2.6mm 2本

    In my case the screw points connecting the old battery the case had fractured or broken. The broken bits needed to be cleaned out of the case before installing the replacement battery. Didn't want any loose fragments rattling about inside.

  5. バッテリーに触る際は、露出している6つのセルに触らないようにご注意ください。
    • バッテリーに触る際は、露出している6つのセルに触らないようにご注意ください。

    • バッテッリーは、ロジックボードに近い方から持ち上げ、上部ケースより外します。

    • この修理ガイドを完成したら、新しく装着したバッテリーのカリブレーションを行なってください。

    • 100%になるまで充電します。充電後も最低2時間はプラグを繋げたままにします。それからプラグを外して、通常通り使用しながら、自然に放電させます。バッテリー残量小のサインが表示されたら、これまでの作業を保存して、スリープ状態になるまで放置してください。スリープ状態に入ったら、少なくとも5時間置きます。それから一気に100%まで充電します。

    • 新しいバッテリーを装着後、通常通り作動しない場合は、MacBook ProのSMCをリセットしなければならない可能性があります。

    What if new battery comes with what looks like plastic around the 6 cells?

    I'm having trouble reconnecting the pins to the new battery cable. Any suggestions?

    Deirdre Rogan - 返信

    The cable on my new battery needed to be massaged to reconnect with the pins. Use your old battery as an example for how the cable should sit in the empty space.

    Joe Ponce - 返信

    In my case, the replacement battery cable was quite stiff. In order to properly connect it to the logic board, BEFORE screwing the battery into the board, I carefully bent the cable and I connected it to the board. AFTER connecting the cable, carefully move the part of the batter closest to the logic board into place, and take care of those screws first.

I followed the directions in the reverse order, but now I have the old battery in my laptop again. Help?

Jenny Doehammer - 返信

I love you Jenny. That is all.

Darren Embry -

Great guide. Identified my parts, ordered them per the suggestions, and had the battery swapped out in 10 minutes. I like to use a magnetic sheet to hold and organize my screws for repairs like this - it keeps the proper size screws in the proper holes. If you don't have access to magnetic sheeting like I do from my graphics shop, an oval car magnet or a fridge magnet will work as well. The screwdriver recommended are of better quality than I expected. Thanks Ifixit.

After installing new battery Macbook air says "battery not charging" *has an X on the battery indicator*.

The MACsafe2 charger has an orange light.

The battery information indicates;

battery installed: yes

Full charge capacity: 5000 (mAh).

Charge remaining: no

Fully charged: no

Charging: no

cycle count: 0

Amperage(mA): 0

Voltage(Mv): 7500

Did a SMC reset a few time.. still no luck. please help

awesome instructions…it worked! My MacBook Air 2012 now has a better battery and it was easy. Thank you

Jeffrey Louden - 返信

Please note that the screws holding the lower case on go in at a slight angle. If you don’t hold the screwdriver at this angle the tiny torx bit won’t mate properly with the head of the screw and you could damage the screw or the bit. If you don’t screw them back in at the correct angle you could have the same problem, or strip the threads on the case and/or have the screws sticking out a bit and they could snag on or scratch something. However, the instructions are correct.

A new life for my MacBook Air!

fstoer - 返信

I followed this guide and the batter connector has come loose twice now. The first time I opened the case back up and rearranged the cable before plugging it back in. This fix lasted less than 24 hours.

Does anyone have any advice for me before I go in and try again?

Sarah - 返信

thanks worked perfectly and appreciate the help!

I am now having a problem with my battery install that was very successful and working a week ago. No response yet from ifixit. I think their battery was bad or it has messed up the battery software in the macbook air. Not very happy or satisfied at this point as my mac is no longer functional the new battery battery will no longer hold charge at all. I am very sorry I disposed of the original too quickly now. 80% charge is better than none.

Jim Lukens - 返信

Was super easy to replace the battery in my MBA. It took me about 15 minutes to do it.

Christina - 返信

Thankfully Ifixit has responded and is very helpful and is issuing me a new battery to replace the one that is not working. I will get it a week or so and try again. fingers crossed.

Jim Lukens - 返信

So I ended up with another vendor battery but even it has issues. Apple Store said this age mac air is beyond the range of their diagnostic tools and its about finding a high quality battery vs anything being wrong with the mac itself software/hardware all of the presenting issues are low battery quality related. Apparently battery quality is not the best across all manufacturers. Take that for what its worth but its what I heard.

Apple store agreed even the latest MacAir is not much faster/better because processor is still very similar, Storage / RAM are the largest changes so its hard to justify new Mac cost. They actually said if I could nurse battery as is and try others if they fail is probably the best way to address. It works fine charges to 100, counts cycles, but cuts out randomly under 20%. I still get good 4 hours use which is fine for me.

Ifixit has been extremely helpful and has offered to refund me so I have been happy with Ifixit & this guide was fully correct and will continue to use ifixit.

Jim Lukens -

Installed the new battery and it will not charge. Anyone able to help?
