Re: Dell Precision M3800 won't turn on
Actually, I haven't been in to Windows on this laptop. Just got in to the Dell Diagnostics. It is a pre-Windows thing.
VCC going in to PU200 is supposed to be about 19V. Also, I noticed that PR213 on the broken board looks a bit off. It's numbers on the surface are gone and the center has a light area. I measured its resistance and got 12.7K Ohms but the schematics say it should be 10 Ohms. Included is a pic of the bad resistor and a pic of a good resistor on the working board. Maybe this will help someone. The bad resistor is dropping the voltage that is going in to PU200 to 2.9V.
