MacBook Pro overcurrent and overvoltage detected

Hello, and thank you for helping.

I have a mid 2010 13” MacBook Pro that worked flawlessly (and still does, sort of). One day, when the battery was at 0% I plugged it in and turned it on. The chime ringed but it shut off immediately. I tried turning it on again, but it did the same thing.

I found a way to turn it on that consists on pressing the power button for 5 seconds, and when it shuts off press it again for ~10 seconds. Later I discovered that this is an SMC protection mechanism.

When it turns on, it takes a long time to do so. And when it finally boots it runs really slowly, which is a sign that a sensor is wrong. But, when I was trying to diagnose it, i found out that booting it without the battery the machine works normally.

I ran ASD on the machine to see what was failing, and indeed it’s sensor issues.

DC In (ID0R) (Current Sensor DC IN 0 Rail) is reading 8.243A, when it should be between 0 to 5 A

Battery - BMON Eng. (IP0R) (Current Sensor PBUS 0 Rail)is reading 9.166A, when it should be between 0 to 8.4A

CPU 0 Core (VC0C) (Voltage sensor CPU 0 Core) is reading 3.299 V, when it should be 0 to 1.5V

At this point I don’t know how to proceed, I really don’t know component level repairs and don’t know where is the problem itself. I would really appreciate any help.

Thank you!
