Motherboard does not boot what to do?

I played Gta V on my laptop and after a while the laptop just turned off. It opened and after the login it switched off directly and now it is no longer working. When I plug in the cable the led lights up but it shows no reaction when I press the power button.

Would do the following:

Remove the battery, then plug in the power cable and switch on the laptop.

If there's still no reaction> then loosen the flap on the back where the hard disk is underneath (try it out). Turn on the laptop if there's no picture and nothing is coming (no beep, etc.) Probably bigger
