Desktop Screen gets dim on battery power

[tucson146]

I upgraded from 8.1 to windows 10 a few days after I purchased it.  Everything works well.  however,  only on battery power when I return to the desktop the screen dims a bit.  As soon as I open a window,  the screen returns to full brightness (taking about 10 seconds).  I just didn't notice if it did this with 8.1

Does anyone know if this is a Win 10 thing or something with the laptop.

Thanks,  Bill

I am not yet running Windows 10 -- it is possibly connected.

Assuming for the moment that you have all your Drivers installed, that everything is working about as expected, and the setup is similar / same to Windows 8.1, the following may resolve your issue:

Adjust Display Advanced Power Settings

Thx for the ideas Dragon-Fur,  I tried all adjustments in advanced to no avail.

Bill,

Can you verify that you have installed the requisite Windows 10 HP Drivers for your system?

HP Pavilion Notebook - 17-g015dx (ENERGY STAR)

In particular, although you ought to have installed your HP W10 Drivers by now, I am curious about the following drivers / software.

------------------------------------------------------------------------------

Intel Chipset Installation Utility and Driver:

Version 10.1.1.7 Rev.A - sp71908.exe

------------------------------------------------------------------------------

Intel Collaborative Processor Performance Control (CPPC) Driver:

Version 1.0.0.1018 Rev.B - sp72039.exe

------------------------------------------------------------------------------

Intel Dynamic Platform and Thermal Framework Client Driver:

Version 8.1.10600.147 Rev.A - sp71915.exe

------------------------------------------------------------------------------

Intel High-Definition (HD) Graphics Driver:

Version 10.18.15.4240 Rev.A - sp71920.exe

------------------------------------------------------------------------------

HP Notebook System BIOS Update (Intel Processors):

Version F.52 Rev.A - sp72877.exe

Caveat:  Do not attempt to update your BIOS unless you have the system completely backed up.  Always consider that BIOS updates carry with them an inherent  risk factor.  Reference:

I have updated all the drivers you listed.  No change in screen dimming. As I say,  all works well except for the dimming when returning to desktop and then getting brighter after opening a window (only when on battery power).

Thanks,  Bill

Bill,

The only other thing I can think of at the moment is that your Intel Graphics is set to other than the Display settings.

• Intel® Graphics – or other specific Graphics adjustment -- may be available.

As a general rule, you can reach your Graphics card adjustments from the Desktop.

Right-Click on clear area of your Desktop > Select Graphics Properties (or similar wording)

Reference:

Adjust Display Advanced Power Settings

I may well be missing something; I will post back when I find something to add.

Thx again.  I tried various battery saver settings - no good.  Battery saver features was off to begin with. Nothing seems to reflect such an option.

I'll keep poking around and see what I can.  I'm guessing it may be a built in feature. I can see the advantage to have the screen dim at the desktop while on battery power,  as annoying as it is.

I have dug at this a bit more -- not running Windows 10 yet so the going is slow. 

I did find a couple of new items and I have added that information to my Adjust Display document.  I don't know if the information will help you; it may be worth checking, at least.

Excerpted

• Windows 10 - Screen BrightnessWindows 10 has several spots where you can check and / or adjust the Screen Brightness.

Windows 10 – Screen brightness too dark

and...

NOTE: Notebook setups vary – In addition to those shown in the example below, your notebook may provide a setting called “Dim the Display”

• Help, Explanation, and Examples: Dim Display Automatically - Turn On or Off in Windows 8
• Be sure to read the document’s first Note that explains the default behavior for Notebooks that do not support the “Dim Display” Feature!

I don't have those options

I've come to the conclusion that the screen dimming on battery power is built in to the HP laptop.
