1903 - Broke On Battery Brightness Adjustment (missing sliders)-adust_plan_brightness-2.png

I can still adjust brightness for Plugged In mode in the notifications menu and general brightness menu, but there is no way to set it for the Battery mode, when the notebook is unplugged.

Worked fine with 1809 and 17XX (with registry hack as it used to have brightness stuck all the way up).

Any way around it? I heard there is a reg hack that can be used.
Using older Mobile Intel 4 series express Chipset family driver from Microsoft corp WDDM 1.1.

Thanks for any input!

Microsoft is moving away from the old control panel
Try Settings / Ease of Access / Display or High Contrast
Try turning the night light on
you could try to build your own profile (been years since I did that)
But don't remember how

Have you tested whether the one setting applies to both plugged in and battery?

thanks for the reply. display and high contrast have nothing related to the brightness settings for battery mode. Nigh light is a different animal all together. Basically this panel was the only place to adjust it...
Also when creating a custom profile it's the same - both sliders are still missing. Looks like a drivers issue of some kind, but considering it's MS's own driver that is in use, it's even more strange.

Yes that's the problem. I can adjust the slider to 60 for instance (eg. in the action centre) and it becomes the same for both modes. So when I unplug the power cord - the brightness stays the same. Before 1809 I could adjust either mod separately via these two sliders that are now missing. In other words, I can't adjust the brightness for the battery mode at all anymore and there are no remaining sliders related to it in any of the settings.

Looks like they just combined them.
Have you checked Vaio Z website for an updated video panel? I seem to recall the Vaio
had its own app for color and brightness.

it's kinda strange they would do that. As of vaio, they are long gone, sony sold the brand and this one is an older PC, but worked just fine with 1809, so no reason it should stop working now

thanks but that's a little different and it's for win 7

I see some posts on reddit that there are other people with the same issue and different hardware (all intel integrated gpus though), so it's certainly not an isolated incident, and seems like an actual bug with 1903.
