Hello guys, I am not seeing the 'screen brightness' adjustment on this pc though? Normally it would be at the bottom of the Power Plan window. Pressing the FN key and using the up and down arrows or f4 or f5 keys doesn't do it either, help?
Solved! Go to Solution.
Reinstall the video card drivers. You may also want to install the chipset drivers first, reboot the machine and then reinstall the video card drivers.
