Re: very challenging issue! lenovo G50-80?
To give a little more insight:
This is my board type aclu3/aclu4 uma nm-a362 rev1
when you plug in charger the led lights up. you hold the power button led goes off. Press power button turns on again. If you connect the batter the battery led lights up and chargers.. It just does not post no fan, keyboard light. I checked and cleaned ram swapped it around used external display. still black screen. The only strange thing is 7volts on pin5 Pu904
