Re: Macbook pro 13 a1278
yes, one of them is burned, the other is apparently well.
the meter reading is:
3.5 ohms on both sides
3 nf
I can replace it with a standard capacitor?
any ideas?

Hello, I am looking for any and all files related to the mainboard for 820-2565-A (13" Macbook Pro A1278 mid 2012) schematics/board view.
I looked through forum search results and google and was unable to find a board view file, I found a pdf of all the schematics but I don't know where the parts physically are on the board as this is my first macbook board level repair attempt.
The macbook charger has a green light, the battery has been replaced and OS reports Normal status but Not charging. After cleaning a corroded capacitor it crumbled off the board. There... -
Hi all!
This is my first post and also one of my first "deep dives" into electronic repair. I'm used to doing basic tasks with computers, like SSD/CPU replacement, thermal past re-application, etc. So here's the story...
I have a MacBook Air M1 that I bought to repair (I know, I'm weird; though I'm a CompSci major and want to learn more
, and it will not display anything on the internal display. I have verified that there's no backlight, as I booted the laptop and shined a flashlight on it and there's no display; it does completely boot up, and shows fine on an external...

Hello...
My sister purchased an M2 MacBook Air a year and a half ago. While she was using it a week ago, it randomly shut off and no longer powers on. There are no signs of life and not even the MagSafe indicator LED lights up.
We took it to Apple and they disconnected the battery and tried a bunch of stuff before they declared the logic board "brain dead" and quoted us about £567 to replace it. Typical of them...
eBay replacements run about £367 with the Touch ID sensor included.
I did consider to probe the logic board for shorts... -
Hi everyone!
I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.
I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...06-27-2025, 08:54 AM
