MacBook Pro - Water Damage
I have a mid-2015 MacBook Pro that suffered a water spill. It would start to boot, then re-boot part way through. I pulled it all apart (after a week) and found no corrosion that I could see. I pulled the drive and was able to save the data to another Mac using an external enclosure. I had a spare LogicBoard and swapped that in - having the exact same issue. The keyboard and track pad work fine.
Tried internet recovery and boot/install Catalina from a USB drive - same issue. With the USB drive, it starts to load the OS, then reboots after about 60 seconds.
Aside from the logic board, there isn't much left? I should mention that the batteries are flat dead. I tried also with the batteries disconnected.
Any thoughts or advice?
