Nokia 6300 display lighting

The display light will not turn off with the options suggested. It'll do only according to a preset time. The option suggested are for turning off the blue lights on the side of the phone.

 

Display does not turn off when pc is idle

Just did all the suggestions. Did not work. Display does not turn off.

This issue was from the beginning when I downloaded Win 10. I had Win 8.1 and the display always turned off as I set it.

My pc is HP Pavilion Touchsmart 23 all-in-one. According to "checking for updated drivers on display and monitors", I always get the response that the drivers currently installed are the correct ones.

 

PC lights and fans turn on but not screen, keyboard, or mouse.

I’ve had some pc problems this whole week, from start ups taking forever, and it going to sleep and not be able to turn back on, and now when I turn it on, i can hear its little start up noises of the fan and such, the leds light up but nothing happens, my screen doesnt light up, nor my keyboard or mouse, and usually I have to hold the power button it turn it off but now one tap and its off so quick.
