Default Lenovo 80e5 g50-80 ACLU3/ACLU4 NM-A361 rev.1.0 non si accende

Lenovo 80e5 g50-80 ACLU3/ACLU4 NM-A361 rev.1.0
hello I would like some help, my laptop Lenovo 80e5 g50-80 ACLU3 / ACLU4 NM-A361 rev.1.0 does not turn on. when I insert power the led4 flashes and the fan moves a little. I only found the diagram pdf 2014-09 -10 REV0.4. I would need for BoardViewer the version for my ACLU3 / ACLU4 NM-A361 rev.1 and also schematic pdf. Also doing measurements with the multimeter I find on the line + 1.35_VGS to ground 6.06 ohm. According to me too low.
am I facing a short circuit?
that line affects the rams soldered on the board
thanks

Use NM-A271 schematic. Its quite similar.Start by measuring resistance on all coils. Voltage on pin1-4-8 of PQ301/PQ302?? With onboard soldered memory, the resistance may be correct.
