Hello, Acer Predator GH51M LA-K862P NO POWER I am experiencing a different version of the problem in the post. My laptop was working smoothly, I was receiving images via hdmi via monitor.I ordered a new lcd panel because the LCD screen was broken.When I wanted to turn on my laptop after replacing the LCD screen, my laptop was dead. Currently, there is no power, no light, no reaction on the laptop, do you think that in this case, could the GPU or CPU of my laptop be burnt? I read in some forums that this kind of error can occur if the LCD screen is replaced while the battery is plugged in. When I replaced the LCD panel, my laptop was completely turned off. But the battery was unfortunately installed.

I need your valuable help in this matter. Which steps can I follow to determine the fault? Basically, which parts do I need to measure on the schematic? I would be very grateful if you have the opportunity and if you can take the time to help me.
