Thanks for joining the Graphics community JB97.
I would need more information in regards to your system, so would you please reply back to me with this data:
- Which version of Windows do you have?
- Which is the model number of your laptop? Graphics Drivers — How to Identify Your Intel® Graphics Controller
o Click the Windows icon, and then right-click Computer.
o Select Properties.
o Find System Type on the Properties window, and then note the processor model.
- What is the graphics driver version? Graphics Drivers — Intel® Graphics Driver Frequently Asked Questions (FAQ)
Could you please attach the DX Diag report for your system?
(Start -> Run -> dxdiag -> Save All Information).
I also recommend you to check if you are running the latest BIOS version available for your system.
I have the same issue as the original poster - in order to not wear down my battery, I usually take the battery out and use it on AC only. The brightness dims on certain dark-themed websites and apps such as Spotify, which is slightly annoying as I only would like the Intel Display Power Saving technology to be switched on when using the battery. Switching it off has no affect, as not only would I like to keep the option enabled on battery, but it doesn't change when on AC only.
I'm using an HP Envy 15-J105SA (Intel i7-4700MQ with HD Graphics 4600), with Windows 8.1 Core. The driver version for HD Graphics is at 10.18.10.3304 but I believe the issue also occurs on the latest drivers (which I was using until I reset my PC about a week ago). It seems like this is a bug with the HD Graphics drivers.
Edit: I believe this thread also has a very similar issue.
Edit 2: Running the latest BIOS, and I've uploaded my DxDiag file here.
