Toshiba laptop black screen?

My laptop (Toshiba Satellite L850) has a screen when starting up, but after about 2 minutes it gets very dark, so I can only see with a flashlight or something. Does anyone know what I can do about it?

Check power saving settings. Manually adjust the brightness. If this is at its maximum and the screen is still dark, there's a problem with the backlight of the display.

Then you would need a new display.

How do I check the power saving setting? The brightness doesn't go any higher
