Unable to dim brightness in Dell Studio 1749 laptop

Unable to dim brightness in Dell Studio 1749 laptop: everything I have tried does not allow me to dim the over-bright screen using the win 10 customization tools? Most suggestion offer tweaks that might not be reversed?

 

All of a sudden, my laptop screen's brightness dimmed itself even though it is saying it is at full brightness.

Hi 8MMA,

Welcome to Microsoft Community.

I'm Hahn and I'm here to help you with your concern.

If your laptop screen has dimmed itself even though it is saying it is at full brightness, Microsoft Edge updates generally do not cause this problem.

There are a few things you can try to troubleshoot the issue:



Check the Power Settings: Your laptop's power settings can affect the brightness of the screen. Make sure that the power plan you are using is set to "High Performance" and that the "Dim the display" setting is disabled.



Check the Display Settings: You can also check the display settings on your laptop to ensure that the brightness is set to the highest level. On Windows, you can do this by right-clicking on the desktop and selecting "Display settings". Then, adjust the brightness slider to the highest level.



Check for Driver Updates: Outdated or incorrect display drivers can cause issues with the brightness of the screen. Check to see if there are any updates available for your graphics driver and install them if necessary.



Disable Adaptive Brightness: Some laptops have a feature called "Adaptive Brightness" that automatically adjusts the brightness of the screen based on the ambient lighting. This feature can sometimes cause issues with the screen brightness. You can disable this feature by going to the Power Options and then clicking on "Change plan settings" for your selected power plan. Then, click on "Change advanced power settings" and navigate to "Display". Disable the "Adaptive Brightness" option.

Check the power adapter: If the laptop's power adapter fails or is low on power, it may cause the screen to dim. Try using another power adapter or use a battery to determine if this problem is occurring.

Update ACPI drivers: They control power management and brightness adjustment, and it can automatically get the latest drivers from Microsoft's database. Click the Start button and select the Windows Update icon. Click on the "Check for updates" button on the left panel. If an update is available, click the "Install Update" button.

Hope the above information is helpful to you, if there is anything not clear, please do not hesitate to let me know.



Your Sincerely

Screen dimming even at 100% brightness

Hi recently bought a Lenovo laptop, a Lenovo V14-ARE laptop, and as soon as I turned it on I noticed, when I put it on 100% brightness it is bright and vivid but then it dims. After a while, the screen brightens again then proceeds to dim once again in a
few seconds. When I plug it in to charge, the screen is bright and vivid but as soon as I unplug it, it dims. I already left clicked on the power icon in the task bar, went to power options and selected "choose when to turn off the display", clicked "change
advanced power settings", scrolled down to "display" and opened its list, but the only option I have for the display's list is "turn off display after", in the Youtube videos I've seen they have an "adaptive brightness" setting or something like that and that
fixes their problem but I don't have that option. My power plan is also in high performance and everything is "on battery" but the problem still happens.

Can this problem be fixed?
