Remove the battery and keep the power button held for about 15 seconds. Try turning it on again with the laptop charger only and see if it works. If it does not turn on, the motherboard probably died. It's a common problem with laptops that have something else than intel graphics and they get exposed to that kind of heat. What happens is that the heat gets so high that the GPU chip desolders itself from the motherboard. They can repair it, but they usually fail again after a few weeks.
