Hello everyone!!
Problem with laptop Pegatron A15HE, has an Asus A15HC motherboard.
Found boardview only, no schematic.
First problem was a short on U8000(ISL95831) pin 38(PHASEG) TO GND.
So i remove it and check Q8011 for any other short between GND or phase to ugate
and found it ok. So i replace ISL95831 with a new one. Now after power on, ISL95831
pin 38(PHASEG) and pin39(UGATEG) get shorted between them(not in relation to gnd), change it again and same thing happens AFTER the first power on. When i change it, measurements between pin 38 and pin 39, pin 38 to gnd, and pin 39 to gnd(with CPU removed) are ok. Short begins with the first power on. All other voltages from ISL95831
are ok. Any ideas? Faulty CPU?
Attach boardview and program for viewing it.
Thanks
