简介
按照本指南移除触控板 —— 要么更换它，要么将它取出以便你可以使用电池。
为了你的安全，请在开始之前将 MacBook Pro 的电池放电至25％以下。如果不小心刺破，充电的锂离子电池会产生危险且无法控制的火灾。
你所需要的
-
-
开机，并打开终端。
-
将以下命令复制粘贴到（或完全键入）终端窗口中：
-
sudo nvram AutoBoot=%00
-
按[回车]。如果出现钥匙提示，请输入管理员密码（开机密码）并再次按[回车]。注意：您的回车键也可能标有「⏎」或 return。
-
sudo nvram AutoBoot=%03
-
-
-
关闭显示屏并翻转整个笔记本电脑。使用P5 五角螺丝刀卸下固定底壳的六个螺丝，长度如下：
-
四颗 4.7 mm 螺丝
-
两颗 6.6 mm 螺丝
I miss a printable template to leave the screws and removed parts on it for future identification when reassembly, linked maybe with the location in the Macbook, or with the number of the step.
-
-
-
将抽吸手柄按到底壳前缘附近，螺丝孔之间。
-
提起吸力手柄，足以打开底壳下方的小间隙。
Throw away this suction cup and get another. It just doesn't work! Luckily I had one that does work in my tool kit.
-
-
-
将底壳牢固地拉向 MacBook 的前部（远离合页区域），以分离固定底壳的最后一个夹子。
-
首先在一个角落拉，然后在另一个角落拉。
this step must require a lot of force. I tried to pull it with the plastic hookie thing from the ifixit set by hooking it in one of the screw holes — the tip of the hookie thing broke.
PLEASE DON'T PULL!!!
Instead just gently push with plastic pick from the other side (where vents outputs are) towards the center... Cover will very easily open that way.
I hope iFixit will correct this step.
Came here to share exactly this.
Robert -
That's definitely how this step should be done. Thanks!
VovS -
If someone has a photo to share regarding this comment, it might be very useful. Thanks.
I used a screwdriver at 45 degrees angle and pushed the cover from the hinges, it worked really smooth. I had it close to the corners.
Yeah, definitely don't pull; if you do, wear protective gloves. Mine was stuck so strongly that I just cut my palm quite deep.
You would think ifixit would investigate why the last step required them to pull with great force to remove the bottom case lid as the solution.
It's counter-intuitive to use an excessive method to remove a part.
There's always an easier way. It's frustrating because you can't see inside.
Using the iFixit opening Tool in the hinge opening required close to no force to open.
Ah... after attempting to 'pull' this rear cover off, to no avail, I tried to coax the cover off with a nylon pry tool. MUCH better! iFixIt will do well to amend it's recommendation to 'pull' this cover in any way. All I wanted to do was a little house cleaning and exorcize the dust bunnies that took up residence in my MBP's fans. Today is much quieter. Thank you all for pointing out the obvious.

取下底壳。
-
将其固定到位并将滑动夹子对准显示屏合页附近。向下按并将盖子滑向合页。它应该在夹扣合上时停止滑动。
-
当滑动夹完全啮合且下壳看起来正确对齐时，用力向下按下底壳以啮合四个隐藏的夹子。你应该感觉到并听到它们啮合到位。
If I had it all to do over, again, I would blow out the dust with compressed air at this point. During the disassembly, I kept encountering little dust bunnies, and I was very worried that one would get caught in one of the connectors when I plugged everything back up (which wouldn’t get discovered until I put it all back together and tried out all of the components).

-
剥离并取下最靠近电池的主板边缘的大矩形电池板盖。
-
如果盖子不易剥落，请使用 iOpener，吹风机或热风枪轻轻加热以软化下面的粘合剂，然后再试一次。
-
-
-
-
将电池板数据线从电池板上的插座中滑出，然后将其完全取出。
Bonjour, super Tuto, petite question elle sert a quoi cette nappe , et quesqui se passe si elle est pas branché ?

I dont have the “clicky” feedback from my trackpad anymore - please advise how to fix this
Shadi Saif - 回复
The "clicky" feedback is achieved by electromagnet on the bottom, so for anyone like me who wanted to make sure it is working before connecting battery - it will not.
(MacBook Pro 2019 15” 2 years old) There are 4 screws (2 on the left and 2 on the right, each pair held down by a black metal piece) next to the uppermost 5.8mm screws. What is the size/kind of screw are these? I’d like to purchase these missing items? Please help. A suspicious technician tried to scam me out of money. I asked for my computer back before they could charge me. I decided to do the repairs myself. When I received my laptop back and followed Ifixit instructions I found 2 screws missing and they replaced the original with an unrecognizable rusty screw on the farthest left screw hole, and the black metal pieces were missing as well.

-
将显示器略微打开，但保持 MacBook 倒置。触控板组件应分开并平放在显示屏上。
-
轻轻地将触控板的带状电缆穿过机箱中的插槽。
do not turn the touchpad over, as there are 4+5 very thin spacers/washers, and you might lose them. only the next step warns you about this. dont be me!

Did you manage to buy it somewhere?
Parts list with links to buy them is right at the top of the guide…
Just replaced my trackpad, really easy to do! Thanks again guys!
Is this step necessary? I can’t perform this step as I am attempting to repair water damage and need to remove logic board & most likely replace the battery.
Macrepair SF - 回复
@mac_medic You definitely don’t want the power coming on while the board is wet. In your case, I think powering on the machine to disable Auto Boot would do more damage than it prevents. I agree, skip this step and be prepared to disconnect the battery quickly if the laptop automatically powers on. Good luck!
Jeff Suovanen -
Thats right! You don't want power running while working on your logic board.
Dan -
This did not work when running High Sierra.

Tried this on a 2018 MBP 13” Touchbar (there’s no iFixit guide for this model yet). Need to replace a broken screen.
Luckily I managed to connect to an external screen (Cmd-Down Brightness to switch displays) and enter above command. Seems to work, but there’s another problem with this model - it powers up as soon as any key is pressed……. ffs <gnashes teeth>
Cool_Breeze - 回复
I unscrew the battery first and wrap electrical tape over the logic board battery connector before attempting any repairs to the board. Haven’t had any problems yet and I’ve worked on about 10 of these models already. Also when you open the bottom case use a suction cup at the bottom and pull up then run a plastic spudger along the edges to disconnect the clips. Also only use a plastic spudger on the board. Saw a youtube video from a repair shop and he did not disconnect the power and used all metal tools during the entire process of removing the board. His last step was to disconnect the battery terminal.

Is this step necessary if my mac can turn on? Battery fully dead(

BEFORE YOU START: The included torx head stripped off before I was done (and you might need an additional T4) so stop now and go buy a good one. Also they fail to warn you above to get some blue threadlocker ahead of time.

This command did not work for me and I read that sometime in later 2020 Apple stopped this command from working…any ideas on a work around?
Patrick Machacek - 回复
Not able to do that with damaged screen
richardjgreen - 回复
If you have a damaged screen you can still use a converter from thunderbolt (USB 3) to HDMI and plug your Macbook Pro to your TV as monitor display. Just make sure to chose the right Source (HDMI IN) in your TV. I did it and to make it work I unplug and plug again in my Macbook and so I could disable the Auto boot
Roberto Sanchez Bustos -
Hi. This does not work on 2018 13” MacBook Pro with Touch Bar. I did exactly this to disable auto boot. But when I check by using nvram -p it says: auto-boot true. Am I doing something incorrectly? I did everything step by step. Copied and pasted the sudo command, pressed enter and then entered my password. I have Big Sur 11.1 installed. Is there any other way since I need to replace the screen. Thank you. Adrian
Adrian Vizik - 回复
Hi everyone. This is also a little pointless if you can’t see anything on the screen, and you don’t have a display adapter to USB C to display it. I agree with Brian about removing the back and disconnecting the battery cable before you even think about opening the lid of the MacBook. Applying the insulation tape is also a handy little tip that just makes sure there is no way to discharge from either the board or battery.
Roberto Enrieu - 回复
running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted
result: `AutoBoot %00`
Marek Polák - 回复
Running Big Sur 11.6.7 on a 2019 16" MBP, it's "auto-boot". So it's:
nvram -p | grep 'auto-boot'to display the current state, the default istrue- and then to change it,sudo nvram auto-boot=falsewhich turns it off.Ed Mechem -
This step is completely unnecessary if you follow the guide to disconnect the battery properly. Just put some tape between the battery and logic board connection to prevent it from accidentally touching and therefore powering on the laptop.
Grant Ormsby - 回复
It took me a few tries to make this command work, as I was able to copy and paste the command into Terminal, but could not type in my laptop’s password. I finally typed my password into a text document, copied it (command C), and then pasted it into Terminal and it worked.

I didn’t do this. Mine never auto-booted before I replaced the battery. Now it does.

BEFORE YOU DO ANYTHING - CHECK THE BATTERY!
I-fixit sent me a bad battery, which I didn’t realize until it was already install. They sent me a new one, but I wasted hours uninstalling and reinstalled.
Get a volt meter and measure the voltage on the output of the battery pack. If it reads 0 V, SEND IT BACK. It should read over 2 V.
bcardanha - 回复
I've just received my replacement battery and it reads 0,042V between the two main connectors. Do you think it's dead?

When I did this from Terminal.app within Recovery Mode, the “sudo” was not recognized but I could invoke it without the sudo part. It seems to have been accepted when looking at “nvram -p”
johann beda - 回复
When in Recovery Mode, you already have superuser powers. So you don't need to prefix commands with the sudo command to invoke them with root privileges; you already have them. Do a
pwd(print working directory) after opening Terminal in Recovery Mode, and you'll see that you're in the root user's directory.Ed Mechem -
I received the battery kit for my 2018 MacBook Pro and as per the above comment from bcardanha - Oct 12, 2021, I checked the voltage on the pads marked + and - . It was zero volts so I panicked a bit.
I sent a message on the iFixiT Facebook page and I got no reply. I finally found the customer service email for Ifixit Europe and sent them an email voicing my concern as I was not keen to work for couple of hours just to discover that the battery is faulty. I had an almost instant reply on the email (kudos to them) and they adviced me to go ahead and install the new battery as the voltage measured when battery is not connected is not relevant.
I took a leap of faith and after two hours… the new battery showed 50% charge and everything seems to be working just fine. I am happy it worked.

After removing the old battery and installing the new battery I powered up the MBP before screwing the bottom on. I discovered the my keyboard would not function. It took a few hours of investigation and frustration that I discovered the track pad power ribbon had become partially dislodged from the trackpad. I was able to see that this through the little machined slot where the battery sat. I had to remove the trackpad to reinsert the power ribbon back into the connector in the trackpad. after reassembling and reinstalling the battery etc the keyboard worked. Just food for thought if your run into the keyboard issue.

This should be the default. IMO I tell you to power on - not the lid.

Claire Miesch -
Excellent instructions. I was able to follow and install the new screen. I recommend that you get a good set of tools before you begin. I started with an inexpensive repair kit bought online. The Penta and torx bits failed. I bought an IFIXIT kit with quality bits and I was able to do everything I needed.

If you're not running an admin account the sudo command won't work (which honestly, you should not be running admin). Rather than logging in to your admin amount via the OS, in the terminal type "login [admin username]," then the password and you'll be able to do the sudo command as described above. Once you're complete, type "logout [admin username]" and you'll be good to go. Obviously replace [admin username] with whatever the account name for your admin user is.

For those unable to complete this step because the screen is too damaged I recommend leaving your macbook on until the battery dies.

Just replaced my 2018 15" MBP battery. Running Sonoma.
I found no way to disable AutoBoot (The status can be checked in the Power section of system report).
Anyway, i left my battery completely drain before opening the MBP, and had no issues during the process.
Cédric Bontems - 回复
After sending this command in terminal when I checked what happens if I now open the lid, instead the screen lit slightly up (still black) then a battery symbol showing the charging state showed up.
Now, after replacement of the battery, this is all I get to see.
No reset of NVRAM nor PRAM helped.
Currently the new battery charges (58% atm) and it feels like it‘s mocking me.

I suspected the keyboard or TouchID sensor wouldn’t work, so I went on and checked every connector.
I missed connecting the left TouchID sensor from step 31.
