I tried watch dogs for the first time on my laptop (lenovo legion y520), but the laptop got very hot and ran out in the middle of the game. I know he usually turns on again when he is cool again but it has been a good 16 hours since he was overheated and he still does not turn on. Nothing moves and now I don't know what I can do. (Guarantee has already expired)
He is no longer concerned? No signs of life?
I would screw the thing up and look at the mainboard.
I will try
I would spontaneously tap a defective capacitor here. With luck you can swap them yourself, but in the laptop they are usually very small
Study the manual and if you have a second power supply, try it. Caution with power supplies! If the tension is not right, then the laptop is also broken. So read exactly what is on the original and possible replacement for information.
If you don't do it anyway: Make sure that the ventilation slots are clear during operation. However, a programming error by the game or graphics card driver can be to blame for the misery.
If you're unlucky your CPU or motherboard has suffered heat death. Repairing a laptop is time-consuming and usually not profitable. Unless there's only one capacitor on the board, they are cheap and quick to replace.
What you could try sounds stupid, put the laptop in a bag, seal it tightly and put it in the freezer (without battery) for about 15 minutes. Maybe it will help you, had such a case years ago and back then the buyer guaranteed me that this worked.
Another question, try your laptop without a battery, so just start on the network, maybe your battery broke.
