Laptop won't power on

My laptop used to turn on only by opening the screen. few days ago I had a problem with the laptop freezing on the password opening screen,

And I couldn't restart the laptop for a while because the power botton doesn't make any action. Finally after I manage to reboot the laptop and I opened the system screen on page F12 I switched the power on/off from opening the screen to the power botton and still not working and now I can't even power on the laptop
