I've checked on the internet but can't find any info on such a feature, if it exists. Maybe it's the Intel driver exhibiting the same behavior on both OSes? (long shot)Ĭould it be the laptop screen has dynamic brightness built-in? Is there even such a thing for laptop screens? The screen is the LP156WHB-TPA1, made by LG Display Co. Summary Version: If you can’t turn off adaptive brightness then you need to disable the power saving feature in the Intel graphics settings. I suppose part of me understands why the power saving is enabled by default but what an absolute pain the neck. The screen will dynamically adjust its brightness. Now on battery power the laptop will respect the Windows 10 adaptive brightness settings. Control Panel > Device Manager (opens a window) > Display Adaptors > Intel(R). I thought this would be a Windows problem, so I tried running Linux. Try rolling back the display driver to the previous version. Even the BIOS is updated to the latest version. Of course the laptop's drivers are updated to their latest versions. I should note here that the screen brightness changes according to what is displayed on the screen, and not according to lighting conditions. When the laptop runs on batteries, adaptive brightness kicks in. When the laptop is plugged in, there's no adaptive brightness. * I've even tried uninstalling Intel's and nVidia's drivers. * I have disabled the Sensor Monitoring Service under windows services. Step 4: Expand Display, hit Enable adaptive brightness, select On or Off, and then tap OK to confirm the setting. Step 3: Click Change advanced power settings to move on.

Step 2: Tap Choose when to turn off the display in the left settings. * I have disabled adaptive brightness in Intel's graphics control panel. Steps to enable/disable adaptive brightness in Windows 10: Step 1: Open Power Options. Now locate the Display options, then Enable adaptive brightness. In this new window, find and click on the link for 'Change advanced power settings'. In the window that pops up, click on Change Plan Settings next to the selected power plan. * I have disabled adaptive brightness in the windows control panel, under advanced power plan settings. In the related settings section, click the link for Additional Power Settings. My problem is that, when the laptop is running on battery, I can't disable adaptive brightness, no matter what I try. Recently I bought a Dell Inspiron 3542, built on the Intel i7-4510U with Intel HD4400 graphics and also an nVidia 840M. Brightness changes according to what's on screen. TL DR: I've tried everything to disable adaptive brightness with no luck.
