My MacBook doesn‘t turn on after SMC reset. I've found on Apple pages that this can happen if you reset the SMC without your MacBook connected to its AC power adapter. I've also tried PRAM and SMC reset and nothing.

Black screen, no charging sound and battery picture when connecting to power supply.

I wonder what is this little yellow button on logic board for? Do any of you have a problem like me?

Does anybody know location of power on pads?

The issue is, i need to press the power button then plug it in to make the MBP start. Then the fan is in full blast while im using it.

Just upgraded to Sonoma via Opencore, works great.

My Main question is; what is the issue when starting the laptop. is there a hardware problem?

Thanks

I'm curious if its a the 2016 -> 2017 logic boards are a direct swap as this could be an awesome upgrade to keep me going on a perfectly good 2016 chassis?

Accidentally, some of the black film on the bottom chassi, underneath the logicboard, got removed (some was accidentally scraped off, some got removed because I spilled solvent when removing the battery adhesive).

Is the purpose of this film just to isolate the logic board from the metal of the bottom chassi? If so - can I fix my problem by covering the lost spots of black film with kapton tape?

I highlighted the area I'm talking about in the picture attached. Thanks in advance!

I am working on this MacBook, and I have been using it for a few months now without any issues. Yet, I couldn't help but notice that the force trackpad was very weak. I could hear the click, but I could barely even feel it. I took the machine apart, but the trackpad felt fine. After a snapped the lower case back on, the trackpad became weak again. Something happens when I snap the lower case on, and the trackpad loses power. I feel like something might be bent on the lower case, but nothing appears off.

Should I look somewhere else? Why would the trackpad lose power by simply putting on the lower case?

It makes me think that the issue I was dealing with about it running extremely slow was related to this. I think the Mac’s thermal sensors think the Mac is very hot and needs to cool, therefore lowering the performance. So, is there an easy way to fix this? Or would it require a Logic Board replacement?

Alright here’s what I found:

Ran Diagnostics.

FaceTime Still needs help.

Photos hasn’t synced in hours.

And I got this app…

And now I’m getting this error

I did try to replace the Trackpad flex cable, but as you can see, the one on the right it the replacement, the cable was defective when I got it.

I got a MacBook Retina 12" from 2016 from eBay, that apparently has an issue with WiFi/Bluetooth.. I hoped a SMC reset or PRAM reset would help, however, so far, I didn't even get to the point of trying everything.

The Mac currently has no OS installed (flashing folder icon when starting).

I tried a PRAM reset and also an SMC reset, but so far with no success. The weird thing is: I don't even get to recovery mode, where I could get to the disk util.. When holding cmd+r, all I get is the globe with the explanation mark and the error code -1005F.

It's so odd for me. When trying to hold option for boot options, I actually get to those - WiFis don't show up though. The only option I can pick is internet recovery (which of course is not working without WiFi).. I also tried connecting a (custom brand) usb c adapter with a lan cable, but that didn't do anything either at that point.

My first goal now would be to install MacOS, to theoretically be able to use the Mac without WiFi, but with ethernet.. Is it normal, that I can't get to the recovery?

Unfortunately, I don't have another Mac right here to create a bootable drive - that might work, but is not really an option...

Any ideas what to try?

It has FileVault activated, even if you enter the correct encryption password it won't let you install macOS or erase the disk. It does not display any disk drives.

Has anyone had this problem?

As the title says. My MacBook has a slight wobble in the screen. When opening it too far, it just falls open as well.

Is there any way to tighten this or fix the hinge?

Thanks!

When changing the battery, I forgot to hold the yellow button on the logic board, could this be the problem? Will it be necessary to replace the logic board? Or is there another solution?

I already tried resetting the SMC but it didn't help. I checked several times whether everything is connected correctly. Well, I simply don't know how to fix a macbook.
