Liquid spill, system works but is very slow
I have a MacBook Air 2019 that had a small liquid spill.
There was minor corrosion on one spot on the logic board, see pictures. I took it out and cleaned it with isopropanol. Didn’t remove the trackpad.
It took ages to reinstall the system, probably 2 hours. My guess is that the system is throttling. Just creating the user + password + home folder took 20 minutes.
The mouse was very sluggish during internet recovery but worked much better booted into the OS.
I downloaded TG pro to check the sensors and specifically the CPU 1 and 2 are behaving strange, jumping from 60-80-100 degrees C something within 1 sec.
System behaves quite normal booted into OS but haven’t had a chance to really test it. It’s the erratic sensor readout that makes me think something is wrong, along with the sluggish internet recovery and system behavior.
Geekbench scores are normal, 935/1664
I’ve seen another post here where the temp sensor for the battery wasn’t correct, and the problem was solved by replacing the battery.
I don’t have any fault codes in apple diagnostics.
What to do next?
These snapshots are taken right after each other. Seems like the cpu sensors are off?
