Hello, long time no post.
I have a 820-00850 board which has no power, USB provides approximately 5.2v on all ports and 0.05 / 0,06 amps.
We have got
PPBUS_G3H 12.3v
Have not got
PP5V_G3S
I'm unfamiliar with exactly how this model works, aside from a few of louis' videos.
Looking at the board I saw corrosion under Q3440 which was missing pin 3 on the chip side so will need to be replaced. Is this enough to stop the laptop from booting?
The rest of the board looks OK. Is it worth reflowing the U3100 chip on that part of the board?
