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 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 -
Got a 2021 14" MacBook Pro M1 here that died suddenly. No signs of liquid damage. However there was a strong burned smell. Upon removing and flipping the board I found a burned cap C9400 near PMIC U9300. Photos attached. Should I just proceed with replacing U9300 and some of the surrounding caps? Also, I don't have any donor boards from this generation of MacBooks, maybe could locate a compatible cap from an older touchbar model? -
Good morning my dear buddies., Working on a MacBook Air (15-inch, M3, 2024 S. No: L16VWD9H7H), yes very ture!!! Just purchase laptop in Aug' 2024 for about $1900. My friends' daughter is the user, spilled liquid in the very 1st week of usage & did not inform anyone till the stage came that the components started to burn. Now the laptop does not turn on at all, stuck at 5v, most liquid is in the audio area & near all 3 audio chips SN012776B0YBH & most components black & burnt here. I know at this time it is too much to ask but if someone has & can share the Schematics &... -
I would like some help with this MacBook if possible. It came in with not turning on and the Magsafe light was off. After inspecting the logicboard i cannot find any liquid damage and also no burnt or shorted components.
took some measurement and i can see i have fluctuation on PP3V3_S2 and also PP5V_S2_MAIN amongst other rails. Using the thermal camera RC282 & RC283 were pulsing, but after removing these it was still the same.
I then did some investigation into why the rails were pulsing and noticed that P5VS2_PWR_EN (comes from U8100) is also doing the same thing.....
Working...
