I've recently updated my graphics card driver for my laptop.
On start-up the screen will appear extremely dimly lit (about 10% brightness), despite the display adjustor indicating that the brightness is at maximum.
I have to manually switch my graphics processor through CCC, which fixes my brightness, until I restart the computer.
When I close the laptop while it's still turned on, putting it into Idle mode, and then open the laptop, it will start back up as usual, but the display will remain off.
