MacBook Pro A1707 with water damage power 20V 0.03A(picture attached), power button do nothing, only black screen pictures of water damage attached motherboard 820-00281-A goal: get user data Please advise.

Now it shows(immediately) same error but at the end "... - 0xB(11)]"

We can enter DFU mode, but Apple Configurator reviving stuck for about 10 minutes and then shows an error. screenshots attached

We can't enter DFU mode, host mac doesn't see anything attached images: power loop 0 -> 0.7 thank you

Hi there, We have a new Apple Macbook Pro A1990 which does not power up, no fans, no chime and black screen. We tested USB C port and the results are below: 1. when the board on Apple MacBook Pro connected to the battery --> 20v 0.05amps. Amps goes up to 0.60-0.70 and loops back to 0amps and...

We got DFU mode, revived the MacBook and got access to the data. Thank you for your help.

according my experience, if the board is in DFU mode, when you connect it to another Mac with apple configuration2 , it detects and shows it on the screen. Also the GPU and CPU area should be getting warm I think. Can you confirm this? But when we connect, it does not detect it in DFU mode...

87W is ok?

Thank you. I connected the board directly to Mac Mini over charger cable and opened Apple Configurator 2, it did not detect it in DFU mode. No activity on Apple Configurator 2 at all. I have a few questions. When connected to charging cable, i do not feel any warmness on GPU and CPU. Also...

Hi Guys, We have an Apple MacBook Pro A2141 that did not turn on. USB-C meter showed stuck at 5V could not switch to 20V. We opened the back cover and we saw very dusty PCB. Removed PCB and checked under the microscope for possible corrosion. parts near to power chips / USB-C - 4 of them, were...

I reinspected the original board of the audio board/flex and touch ID, and it is very clean and nice.

I put the L7400 chips back in place on good and customer boards. Did a diode mode to the ground, and they have similar ohm on both sides? 215-400 Ohms. CPU is getting warm, the board charges the iPhone, and also getting charged from the USB-C cable. Does it mean the CPU works fine? Your...

Hi there. I have an Apple Macbook Air A2179 with water damage. It was not charging and was stuck on 5v. I removed the board, and there were corrosions on multiple spots I cleaned and resoldered using flux to make sure all disconnections connected back again. Then I connected the charging cable...

Yes, I saw that link. Almost the same issue. Thank you very much for your help. I learned a lot of valuable things.

If one chip got damaged, not possible to get this board alive. Correct?

Hi there. I checked the diode mode reading from L9080 to the ground and it is 0.3029v and L9580 is 0.1275v. I also checked these readings on a donor board and both numbers on diode mode to ground L9080/L9580 is 0.4042v. Please advise. Thanks.
