Lenovo IdeaPad FLEX 5-1570 81CA totally dead
Hi, Does anyone have the boardview for Lenovo IdeaPad FLEX 5-1570 81CA LA-E541P. Schematics is posted but I need little help finding the components. The motherboard in this is CIUYA/SA/SB/SD LA-E541P. I am not getting max voltage on pin 1 of this chip PU703 ISL88739HRZ, getting only 2.254, is this voltage correct for the chip to operate??? Before this there is a resistor PR729 392K, I want the location of this resistor. Any help will be greatly appreciated. Thanks

Re: La-e541p
I found the resistor & across this, on both ends I am getting 2.25 volt & on the other end it 19V which is correct. The resistor value is correct 392K. The N-Channel MOSFET PQ740, Drain I am getting 19 volts & on the Gate there should be a high voltage but here the volts fluctuates from .25 to .75, bouncing up & down & zero volts on source. Here I should get nearly 24 volts. Any tips will be a great help.
