Hello
Laptop - Lenovo Z50-70
Motherboard: ACLUA/ACLUB NM-A273 Rev:1.0
Vendor: HannStar
I was doing some stuff on it utill I saw low battery notification. I have plugged AC adapter and immediately screen went blank. I thought that I was too late with plugging. However it stopped working after this. No LED.
I have checked the board for short circuits.
I noticed a malfunctioning mosfet - PQ302, so I have desoldered it. I checked its resistance, and it's really broken - R<1Ω
However, pins 5, 6, 7 and 8 are still shorted... -
