I have done 3x CPU swaps to 820-00244.
Each one of these boards has initially had a burned up U7210 and L7210 which killed the CPU, the boards all have no power originally. I then changed CPU to new CPU and all 3 of the boards turned on. The problem is that all...
Hi,
I have a liquid damaged 820-00850.
I had to replace U7800, U8250, U3730 and UB000 to clear all of the short circuits from the liquid damage.
I replaced all 4 UCB-C Charging chips (UB300, UB400, U3100, U3200)
After replacing all 4 charging chips I plugged the device into power and...
Hi thanks again for your support.
I now have a ROM reader, I have a good ROM dump from a good A1990.
Is the data at jeopardy if the ROM dump has the wrong serial number/UUID?
Thanks again.
L7211 is very stable at .95V
Unfortunately I can't restore the T2 as the data is very important.
Apologies, but when you say check for USB activity, what do you mean?
Thanks :)

Now the MacBook boots normally but it is not detecting internal SSD (Boots to...

The symptoms were that the MacBook got really hot, shut down and will not turn back on.
I have inspected the board closely and have been unable to find any damage or short circuits. The when attempting to boot the board, it...
Thank you very much for the response.
3V3_S5 is 1mv - I checked for short to ground and the line has a normal diode reading. Looks like U7800 creates 3V3_S5?
0v9 NAND - 0.9v
1v8 NAND - 1.8v
2v5 NAND - 2.5v
Hi, first time poster, thank you for everything you guys do here.
I have 820-01041 that had water spilled through the keyboard. The visible damage/corrosion on the Logic Board was minimal.
The only visible damage was located around the CPU/GPU Phase chips (U7220, U7230, QA340).. again very...
