Re: Macbook a2159 Hall sensor not working correctly

Thanks for the detailed answer!

Sadly I don't trust my skills enough to check the board while there is power running through it. Also the U4802 is on the bottom when the board is installed so I would have to find a way to have it powered outside the case.

I did check the trackpad and the touch connector (J5100) and I don't see any issues there. The liquid was mostly around the J5100 connector and the Q5100


I checked with a magnet and the screen turns off when I pass J4800....

Hi All,


New user here found this website because I am having some trouble fixing my macbook A2159.

My wife accidentally pushed over a vase filled with water and just a tiny but splashed into my macbook..

I opened it up and removed the motherboard to clean it with IPA. when it was dry i put it back together and it worked again. But when I close the lid it goes into sleep and it wont turn on the screen when I open the lid.
The computer is running and working but only on an external monitor. I have to reset the computer to have it work...
