I am not sure how to find the enable pin EN . The pdf or .brd file does not lead me to one. In the picture below, the 'enabled by' text does not contain what enables it. Also, the battery is disconnected. Not sure how to proceed with my limited knowledge. -
61K resistance , very highLeave a comment:

very small PCB pad , but no voltage drop on PP3V3_S5 . Is there is a LED on the other side of the board ? So with a short on this circuit, it is more difficult to identify the source or should I remove the board ?
I don't have a thermal cameraLeave a comment:

Both sides of [B]F7000[/B] measure 12.66 V to ground. That is PPBUS_G3H and PPVBAT_G3H_CHGR_REG. Diode mode is 272 on both sides.

No liquid damage , it just stopped working after keeping the laptop in the car hidden under the floor mat for a hot afternoon . I tried the DFU route and it does not enter DFU mode , it reads as Apple controller and an attempt to revive stops midway probably when trying to run the firmware. I would rather learn something in the process rather than send the unit to Rossmann, so if I need to take the board out I will. I already replaced the battery blindly thinking that it was the failed component....Leave a comment:

newbie questions
Apologies if I am asking the wrong questions , but not sure how else to start:
I have an A2251 / 820-01949 Mac book pro with no power, 20 v on USBC meter and 0.05 Amps. Following this link ( below)
* Do I need to remove the board from case so I can access its other side ? The link calls for measuring PP3v3_S5 ( I suppose this is in diode mode with positive probe on ground) , but I don't know how to do that without removing the board from case.
* I have the FlexBV board , are the values displayed in volts diode mode only ? Because my etekcity multimeter shows...
