For some reason my computer has just started turning the brightness on my laptop to 100% when the battery is connected. This is a seriously pain in my eyes and i usually keep my brightness around 20 unless watched videos. So at first i would just alter the display settings of the 'Balanced (recommended)' power plan and save the changes but it never worked, if my charger fell out and i plugged it back in then it would automatically turn the brightness up to 100%. I created a new power plan to my liking but every time the battery is plugged in it will automatically change back to 'Balanced' and turn the brightness up to 100% I always click the 'Apply' and 'Save Changes' buttons on any change i make to the plans and it works up until the charger is plugged in and as you can imagine it's starting to get slightly annoying. Can anyone advise a solution?
