Hi, have this Mac air, had a tiny drop of corrosion on C7137 but board looks very clean, replaced that capacitor. Mac starts spinning, turns off, then keeps spinning. I have all voltages going down to DDR 1.2v and CPU 1.05 and 1.8v, on display voltage only get 6v and then starts to drop, I have...

The mouse LED turned on, but actually not flashing. L7960 seems shorted, 0.059v. I only have a donorboard without CPU that reads 0.469v nothing else to compare with at hand :(. I have 3.3v on PVCCIO_EN

I saw a tiny solderball pop out under R7270 and R7410, if that can be a hint? Edit: another solder ball popping up from underneath U7270

Hello, I have a touchbar 13 inch that came in dead. Inspected the board with microscope in details, nothing to see no liquid damage or bad IC, board looks as new. I have 1.06v on PPVCC_S0_CPU that drops to 0.76v after some time, and after a while boards turn off. Mouse has activity. Missing...

I had reflowed the SMC and reballed 2 x. I think it might have died in the proces, after replacing it all good :) thanks

Replaced smc and fixed. The liquid spill was near smc so might have screwed it although it did spit out voltages.

Hi, I have an Air 3437 that came in with liquid damage, sometimes rebooting by itself but working. Some corrosion around R5100. Replaced R5100 (reset_l, maybe thats why it was rebooting sometimes), alsoY1915 had a tiny bit of corrosion under it, replaced it. I have orange and green light, the...

Just to make it clear, I have schematics for Baffin and Baffin2. The corresponsing boardviews that came with these are identical, just named different 281 and 928. Maybe its just the wrong boardview that was included and the scematics is OK.

I always buy them, fast :) The IC that are shorted are not in Baffin2 so we have no clue what line is shorted. I have emailed my schematics supplier maybe by now he has the correct one. WIll let you know if I got it. If you need schematics here are a lot listed for free ->...

So i just found out, that is the WRONG schematics dont waste your money on it its for 00821.

yes it is, so they sold me the wrong one :mad: This is what I have => SCHEM,MLB_BAFFIN2

I can't find as my schematics don't match even the 281 is different.... See attached

Attached pics. I have the 00281 will check

Found a short, now I have following issue. The board is an 820-00928-A and I have the boardview and schematics for 820-00928, doesnt say A. Mostly looks identical but the area where I found the short is slightly different, see attached image from my boardview as well as the board in question. Is...

Found the issue, some corrosion on U8005 reballed it and working again. Thanks!

I have SSD_RESET_L = 3.2v. SSD_PWR_EN =3.25v, SSD Nand has 1.2 and 1.8v

So i reassembled the machine, running on battery power. I have all voltages 12v, 1.8v and 3.3v should there be something else?

Yes connected. No short on all SSD powerlines. I get 3.3v and 1.8v but both then drop to 0v One capacitor looks like its a bit corroded, measures still OK though no short on that one. Its C9390 pin 1 thats a bit corroded.

Hi, I have a A1707 820-00281 with the infamous question mark folder. I saw a video of the 1706 witch has a failing probe point in many cases. Any know issues for this A1707 15 inch touchbar with regards to SSD drives failing?

Hi guys I have an 00165 that came in with a tiny bit of corrosion on C7615 and R7611, replaced them. Also customer broke the battery connector, so replaced that as well. Now the mac gets an orange line, fan starts to spin, all voltages come up for DRAM and also CPU Vcore 1.2v, 1.3v and 1.8v...
