Update or Reinstalling the display (Graphics) driver is the ultimate solution to fix screen brightness not working/increasing issue.įollow the steps to update the Display driver: Find the “Display brightness” setting and set the values to be identical.As discussed Outdated, incompatible or corrupted drivers are usually the cause of Windows 10 screen brightness control problems. Simply match them up, then press “Apply” and “OK”, then “Save changes” to the power plan. Both settings have their values set with percentages, so it is easy to check if they align properly and if they need changing. Here you have two settings, one for “On battery” and the other for when “Plugged in”. To make sure that your brightness settings are matched, click on “Change advanced power settings” then scroll down the list of settings to “Display”, expand Display, then expand “Display brightness”. In the plan settings, you can use the “Adjust plan brightness” sliders to try to configure the brightness settings to match, however, this can be a pain to get exactly right due to the lack of a scale. Click on “Change plan settings” for the power plan you normally use. Next, you should click “Change plan settings” on the plan that you generally use, even if it is not the one you are currently using.
This will open a screen where you can choose which power plan you want to use. To configure your power plan, you need to press the Windows key, type “Choose power plan” then hit enter. The solution is to configure your power plan to have the same brightness on both battery and mains power. If you have configured your power plan to have different brightness settings when on mains and battery power, you may end up in the position where your screen’s brightness changes, potentially dramatically, which can be quite annoying. In itself, switching from mains to battery power isn’t bad for the laptop, in fact, it’s an ideal situation to have a laptop with a battery, rather than a purely mains-powered desktop computer. Additionally, if you happen to live or be visiting a place with a power supply that isn’t particularly stable, you may see your laptop switch from mains to battery power occasionally, or even quite regularly. For example, if the computer is plugged in, but the power cable is not seated properly, then the computer may not receive power consistently enough for it to consider itself on mains power. Unfortunately, in some cases, the two can be harder for the computer to tell apart. In most cases the distinction between these two is clear. These battery plans can have different values set for use on battery power as well as on mains power.
In Windows 10 the screen brightness can be set through the battery plans.
