Windows 10: Screen brightness drops (a lot) when I switch to battery since Windows 10 ver 1809 update

I just installed the latest feature update (ver. 1809) for Windows 10 on an Acer Aspire E5-773G laptop . The screen brightness reset to 50% so I adjusted it back it "normal". All other settings remained the same.


However, when I switch to battery (100% charge), the brightness drops a substantial amount. I understand this happens when the machine goes on to battery saver, and there are little gradations in brightness when on battery. I don't want to go into settings every time I plug / unplug the laptop.


Are any others finding this problems or are there any thoughts on a resolution?

Hi,

Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

To manually adjust the screen brightness, we suggest following these troubleshooting steps:

• Click Start, then select Settings.
• Choose System, then select Display.
• Under Brightness and color, move the Change brightness slider to adjust the brightness.

Feel free to post back if you have other concern.

 

On-Battery Screen Brightness Too Dark After Win8.1->Win10 Update


Hey guys,

after updating to Windows 10, I am not able to get the screen brightness to 100% anymore (it is shown to be 100%, but plugging my laptop in, screen brightness will increase to maximum brightness). Screen settings are as shown below.




Maybe anyone has an idea?

I also tried using the command line:





This allows me to change the brightness, however 100% is still not really 100% when on battery.
