Hello,
ACER Nitro 5 AN515-55-774Z ((FH52M LA-J891P REV.1)
Intel Core i7-10750H
RTX 2060 6GB GDDR6
Turned off during normal operation and never turned on again.
After disassembling and connecting to the power supply PLW3 burned out.
Resistances on all chokes are within normal limits except PLW1 and PLW2 (about 0.5 ohms) - powering the video memory.
I am new to repair( Advise what to do next to find the short circuit and fix it.
Or if burned GPU then how to disconnect GPU and use without it.
If there is anything else that needs to be measured,...

Hello everyone, I'm Alexander from Slovakia. I came to this forum because I am interested in soldering, and then a friend gave me a non-working gaming computer, I'm trying to fix it.

Re: Acer Nitro 5 motherboard no power (FH52M LA-J891P)
Good afternoon, I have a laptop Acer Nitro AN515-55-774Z with FM52M LA-J891P Rev 1A. My laptop just turned off and won't turn on again. After applying voltage it simply does not respond. Resistor PRB4 was about 0 volts. I unsoldered the PRB7 resistor to see the changes (picture001.jpg), but after a while PLW3 burned out (picture002). Please tell me what to do.
Thank you....
