Laptop won't turn on

No, the thirty second thing doesn't work.
My laptop got warm as it does with gaming, I excited to my desktop. I left, I came back three minutes later, laptop was dead.
The only hint I can give you is that the power button flashes once when you press it if the laptop is plugged in or if the battery is connected or both.
Is it the power switch? If so what do I have to do.

If it helps, I have an MSI GE70 2PE APACHE PRO.
