Thank you for posting in our Community. To better assist you, I’d like to gather a few more details that will help us pinpoint the issue more accurately:

Have you already updated the Intel Graphics Driver to the latest version available from either Lenovo or Intel's website?
Have you also updated the Lenovo System Interface Foundation, Hotkey Features Integration, or any relevant chipset/ACPI drivers via Lenovo Vantage or the support site?
In Device Manager, under "Monitors," is "Generic PnP Monitor" listed? If not, what is shown?
Under "Display Adapters," what GPU(s) are listed (e.g., Intel UHD, NVIDIA GTX/RTX)?
Have you updated your system BIOS and firmware to the latest version provided by Lenovo?
When you attempt to adjust brightness using the Fn + Brightness keys, does the on-screen indicator appear or change, even if the brightness doesn’t?
Are you using a custom power plan? If so, does switching to the default “Balanced” or “Power Saver” profile make any difference?

Have a nice day!

Best regards,

Hi TG77,

I understand that you have a laptop. Since this is an OEM (Lenovo Thinkpad X1 Xtreme gen 2) original equipment manufacturer device, please take into consideration that our support may be limited since we are not familiar with the technology, settings, customizations, custom drivers, and features that the OEM has designed and installed your system, nevertheless, I will do my best to assist you with your concern.

May I kindly ask if you've had a chance to adjust your system's brightness by navigating to Settings > System > Display and disabling the “Change brightness based on content” option? This step will help us isolate whether the issue is related to a Windows feature or potentially a system-level configuration.

Best regards,

Von M.

Hello TG77,

Thank you for confirming that the setting has always been disabled. Since no changes have occurred and the issue continues, we’ll proceed with further steps to help isolate and resolve the root cause. Based on your input, it seems you're unable to adjust the display brightness via the Windows slider, likely due to the persistent disabled state. After reviewing the issue, I’m pleased to share the following recommended steps:

Disable auto brightness if you have that feature.
1. Go to Windows Settings by searching for Settings
2. Go to System
3. Go to Display
4. Uncheck Change Brightness Automatically
Update the graphics driver to the latest version (try using the latest graphics driver from Intel and your device's manufacturer)
Perform a Clean manual Installation of the graphics driver (try using the latest graphics driver from Intel and your device's manufacturer)
Complete all necessary Windows update
Repair System files
1. Open the Search menu, type Command Prompt, and select Run as administrator.
2. Type chkdsk, then press Enter
3. Type the prompt, then press Enter
4. Now, paste the following two commands and then hit Enter after each to scan and fix issues with the ieframe.dll file:
  - sfc /scanfile=c:\windows\system32\ieframe.dll
  - sfc /verifyfile=c:\windows\system32\ieframe.dll
5. Type assoc, then press Enter
6. Type sfc /scannow, then press Enter
  - Note: The above scans will identify problems with the ieframe.dll file and the other corrupt system files and replace them with their cached copy. After running the scans, check if the brightness slider is now working.

Just to share with you, we have our support link where you can find all of the troubleshooting steps that we’re going to perform. To make it easier for you, here’s our support link: Unable to Update Display Brightness Using the Brightness Slider on Windows

After completing the above steps, please check if the brightness slider functionality has been restored. If the issue persists, I recommend reaching out to Intel support or your device manufacturer for further assistance.

Best regards,

Von M.

Hello TG77,

Thank you for the update, and I appreciate you taking the time to complete all the suggested steps. Since the issue persists and considering that the system in question is a Lenovo ThinkPad X1 Extreme Gen 2, which is an OEM (Original Equipment Manufacturer) device, I will need to further investigate this matter in coordination with the appropriate internal teams. OEM systems may have customized drivers, firmware, or hardware configurations that differ from Intel’s standard reference platforms.

Please allow me some time to look into this further. I’ll keep you updated as soon as I have additional insights or next steps to share.

Thank you for your continued patience and understanding.

Best regards,

Hi again, so this was solution from Lenovo:

As the the brightness can be adjusted (with the third party app) this would indicate this is software related issue and not hardware.

Our recommendation would be to install Lenovo recovery Windows image that can be downloaded from Lenovo support:

If you never reinstalled Windows, you can do a system reset, that way you will have to reinstall programs but your files will stay. Reset your PC - Microsoft Support

I am traveling at the moment, so will try that only in two weeks, when will be at home.
