Good companions I have in my possession an Acer ES1-711 laptop that does nothing when pressing the power button the board is DAY31AMB6C0 REV: C model ZYL. It has a short in line 19v but I can not find out where he is and ask for your help .
Clarify that my knowledge is limited but I like this world and little by little I try to understand and read a lot of information about it.
The checks I have done is that I connect a power supply, if I inject the jack 19v the cables heat up a lot, so I have a fairly large short, I have come to inject only 5v and I am heated PQ37 but I have changed it and it still gives me the heat.
I think you should look in the diagram on page 30 which is the charger, I have lifted the coils that I see have continuity with respect to ground and I have also checked some components seeing that they are good, these components are PQ37; PD9; PD12; PD11 and PD 13. I don't know how to check if pu9 is the one giving me the problem and I don't know where to look anymore,
There is a small problem with the plate and it is that in most of the components it is not screen printed so I have to check it carefully with another component looking for continuity and looking at the plate. There are many capacitors that give me continuity but remove them all I see it useless because I think the short film is somewhere else, apart from the fact that these are attached to the cpu and that may be why they give me continuity.
I enclose the scheme
