Hi,
I have this dead laptop, if I plug the charger I see only charging led light blinking 3 times.
I disassembled it, removed the battery and checked with my multimeter:
red arrow input connector 19v
green arrow first mosfet drain 19v
white arrow first mosfet source 3v
yellow arrow second mosfet 19v
pink arrow 3v
blue arrow third mosfet shorted to ground
current resistor 3 volts on both sides
Any advice? I have a thermal camera and I could inject low voltage if needed.
Thanks in advance
