I have a mid 2012 MBP I have a mid 2012 MBP (i7 dual core) that drank a glass of water two days ago. I did a complete disassemble and a 99 ISO bath on the board. Also redid the thermal paste on the chips. The issues I'm having: after starting up, I was getting crazy (650%) kernel_task CPU usage and Apple Hardware Test results of: 4sns/1/40000000:ipbr-18.330 (Sensor, Current, Power bus is what i've deduced). Lately, i've been getting an occasional instant shutdown when I plug the charger in. At one point (earlier), the CPU would jump when I plugged the charger in. Seems like I have a hardware based power regulation issue that can cause the kernel to go crazy. I'm 14 hours in and don't know where to go. Time to send in?
