Need Schematic Lenovo Yoga 720-13IKB LA-E551P REV 2.0
I have a short measured from a coil and some surrounding caps. So far I am ASSUMING its a 5v circuit.
I have battery charge light.
I have battery and power light.
Battery charges to full (8v) no problem.
Power button responds with power light coming on.
No power up from board.
What is crazy is I cannot locate the 19v rail in this thing. I know its there or I would not have the other rails. I do have a short on a circuit that I assume is a 5v rail. Short to ground along with surrounding caps.

No power problem: power button not light; in your case it's power down, it can be caused by a short in cpu or gpu section; or a bad me region, you can try to flash the bios and ec bios first.
the schematic is unvailablle on the payed forum.Last edited by polytek; 03-09-2019, 04:15 AM.
