It does not turn on unless I hold power down for about 5-8 seconds
If I open the laptop and physically unplug the battery and I start with only the power adaptor, it works. Otherwise, I need to keep the button down for 6 seconds. But! The kernel_task uses 400% CPU and the laptop is very slow.
The onboard diagnostic that returns "No issues found. ADP000".
iStat stays that the battery is always using 18.2A (Charger BMON - I think it is SMC register IB0R).
The board does not have noticeable water damage. I started measuring voltages on the logic board but I need some help. I would be able to substitute a resistor or a capacitor, maybe even an IC if necessary.
Es esta una buena pregunta?

Battery charges fine. Only when the battery connector is connected on the board the laptop is super slow. Otherwise it works fine. I think the SMC thinks that there is really a 18.2A current from the battery and it slow everything down to prevent damages.
