Hp Envy 13-can not turn on

[ravitc]

Hi any suggestion would really help. I have Hp Envy 13 which is AMD.
Model is 13-ar0007AU and motherboard No:18740-1. Problem can't turn on.
After inspecting the motherboard I found 1 SMD broken near switch. Can't find schematic about this board, so not sure what this SMD device number is or the function of this device.[/ATTACH][/ATTACH]

That part is a Hall Sensor aka LID Switch. You can remove it and see if the mb turns on. Later you can replace it.

Remove out but still can't turn on. no current detected when plug in and also on the switch. Thanks

You should focus on dc-in mosfets and charging IC as they are responsible for blocking 19V rail to flow. Check resistance on CLR as there may be shorted +19V rail. Give us measurements of voltage on S-D-G pins of dc-in mosfets. Also resistance readings of the same mosfets.
