Thanks man, I'll check all that when I get back home and if it gets me nowhere, I'll leave it and buy a new laptop when I found one (with a warranty extension this time given the price of the laptop :S)

Also, is there something I can check near GPU ? In terms of voltages or resistor values ?
What about the LCD screen ? Though I don't think that a faulty screen would prevent POSTing or an external display from showing images...

It's really bad the way laptops are made, all soldered, one broken thing and good to be thrown away 🤬...

Hi man, first of all, thanks for your answer ! The problem occurred during video editing so I am not really sure that it is linked to the way I open the lid, or am I wrong ? So if it is the CPU , reballing is a dead end right ? How to check exactly if CPU is working fine given the voltages I can measure around ? Do you have a link or something explaining it please ? Also, do you have schematics for this board and especially the neighborhood of the CPU ? (I have an NM-D562 Rev 2.0 MB) My CPU heats up when the computer starts, same as GPU. I don't have any display anymore so I don't even experience...

Hello everyone !

My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff.

When the black screen appeared, my legion 5 pro was connected to my external monitor...

I think I'll buy a new one as I already invested two weekends with no success...
