Hello, I'm stuck as I have an A1708 which powers up fine on the charger alone but won't boot if the battery is connected.
I've tried a known good battery but still no change.
On USBC alone, F7000 is 13v
On Battery and USBC F7000 climbs from 11v to 12.96v and drops back in a cycle roughly every 6 seconds.
On battery alone F7000 sits around 10.6 and very slowly drops
Resistance on R7061/62 + R5438 + R5439 are all as schematic.
Q7065 diode mode
from pin 5 to pins 1-3 is .219v
from pin 4 to pins 1-3 is .634v
I'm not sure where to check from here
