This battery sign doesn't let me through any system. No BootDeviceManager, no Reinstall menu, no maintenance menu, No SMC reset, no NVRAM reset,...

Its just turning off after showing the red battery sign.

I would like to know, if I could bridge the battery contacts. So I could use it as a desktop PC and know if the logic board is broken or the battery.

Can someone tell me where I have to connect which kind of power?

What i found out:

• The big middle contacts seems to be the output pins with 8,59V.
• The Label on the Battery is telling me that it has 7,56V, which is the battery output?

I would assume that I could bridge the 8,59V pins to the pins on the right side next to the output, but I don't know if this is a good idea and if yes, which contact is plus and which is minus. And what is the single left pin for?

Would be cool if i can start this thing without the battery.

I got one in with a missing key and a spacebar that works but is depressed on the right hand side. What I believe has happened is that the plate that holds the keys so thin that pressing hard on the keys bends in down preventing replacing the keys correctly and if they are replaced they are down and depressed (just like me looking at having to replace this keyboard ;-( .

What Would like to know is if anyone has actually done this repair. Does it has screws or pegs. I did find the part at AliExpress

If it is possible to do, I will try to make a guide but wanted to ask first.

I also could not find a replacement screw set.

I have just replaced a battery for a customer but the MacBook will not power on.

i have followed all steps carefully and check them again but no success.

i placed the MacBook on a low voltage charge as you suggested, I reopened the MacBook and checked all ribbons and connections and everything is how it should be. The little light on the logic board for the battery power is on as well.

is there something I am missing?

Thank you

Judging by the pictures and seller description the logic board doesn't seem to be affected by the spill. Is it possible that the logic board itself is fine, but the power button on keyboard does not work?

I want to make it my first laptop I get back working myself. I've watched tutorials on how to replace the keyboard and I think I can follow them, but troubleshooting the logic board might be too much for me right now.

The issue I ran into was at Step 29 of the following guide:

“The antenna connectors and sockets are extremely fragile. Be very careful to lift only on the connector, and not on the socket itself. Do not lift under the cable, or put any unnecessary strain on it.”

Then I open the back lid while charging it. I can only see the light that I circled in picture is on:

Any guru here? I don't need to fully fix the macbook charging issue, I will let Apple do that. But I really need some data in there. What I wish is that I can turn it on in any way. Copy/send the important files to my Google Drive. Then let Apple do the rest part.

Anyone even knows what that light on is for? Maybe I can try to turn it on by any chance? I try SMC reset thing. No luck:(

I appreciate if someone can answer. Thank you.

When a trackpad is damaged, does that mean that its not doing the clicking movement at all, or the click occurs but will not respond as an action

Diagnostics like this one?

I have a MacBook 12” A1534 (2015) with an broken Logicboard (BAD CPU). I bought a Logicboard from am 2016 MacBook 12” für just 250 Euro. YEAH!

I have built it in. All cables except the USB-C Flex fits front the 2015 into the 2016 Logicboard.

But the battery LED is not lighting up. Is the 2015 battery not compatible with the 2016/2017 Board ?

Are all other Components compatible ? or I need to change also other parts ?

The keyboard backlight and power button still work, but the trackpad, haptic feedback, and the rest of the keys are dead.

External USB keyboard and mouse work through an Apple USB-C to A adapter.

After first reading about this problem, it looks like it was the flex cable from the mainboard to the trackpad that was damaged during the repair. I ordered a new one, but no change to the problem.

After this, I did a continuity check on all the pins on the flex cable with a multimeter and found that one of them did not have continuity. Then I tested the original flex cable, and the same pin did not have continuity on that one either. Because I didn't test the new cable before installing it, I now don't know if this pin is supposed to have continuity or not. Pictures show which pin I am talking about (pointing to the same pin on both ends of the cable).

I have tried to reseat the flex cable connector multiple times on both ends, resetting PRAM, booting in safe mode, and tried to do a SMC reset. SMC reset did not work, as this does not seem to work with an external keyboard (but I have disconnected the battery multiple times, which does the same thing as far as I know).

Now I feel a bit stuck on what to do and would greatly appreciate all help I can get to solve this problem.

I was thinking about tearing it apart, take out the logicboard+speakers/antennae plug it into a usb-c dock, and create a Mac Micro… It is my understanding that when a macbook is closed, but connected to power/video/keyboard it will turn itself on in closed lid mode. But I wonder, would this work without a battery?
