Hello all
I also same problem in Surface pro 4.The cap near ITE chip is shorted, 0.00 ohmios to ground.
But I have not 3v3. I have not 14V in BQ2477 chargue controller. Some circuit is cutting 14V from external Power Supply for overprotection (the battery is out) I am going to try find the shorted element .
For that I will put 3V for other power supply while I see what circuit hot with termal camera
