Windows 10: Windows 10 Pro - Battery power screen dimming

I am running Windows 10 Pro on a Lenovo Yoga and whenever I'm on battery power my screen dims dramatically and brightens again intermittently and constantly. I tried looking it up on line, but it appears that the solution in Windows 10 is different than the solution in 10 Pro and I can't figure out how to to do it. Please help! Thanks!!!

Hi,



Thank you for writing to Microsoft Community Forums.



I understand the inconvenience you are facing after upgrading to Windows 10 from Windows 8.1 operating system. I appreciate your effort in trying to fix the issue.



What is the model number of the device?



I would suggest you to follow the steps mentioned below and let us know if that helps.

Microsoft ACPI-Compliant Control Method battery is a driver that is responsible for the communication between your laptop battery and Windows system. We would recommend you not to uninstall the driver. However, since your

2. Click on System, in the Control Panel.
   
3. After the System Properties window is launched, click "Advanced System Settings" located on the left hand side of the screen.
   
4. In the Advanced System Properties window, click on the
   Hardware tab and select Device Installation Settings.
   
5. When in Device installation settings, select "No, let me choose what to do" and "Never install driver software from Windows update".
   
6. Save the selected preference and restart the system.
   

Hope it helps.

Screen dimming booting into Windows 10 Education

When I boot into Windows 10 Education the screen dims to about 60%. It's happening on the two computers now that have Education version installed on them. Screen brightness is set to 100% under both battery and plugged in power settings. Brightness set to 0 (neutral) in Intel display control panel. Then on reboot, it comes up at 100% brightness and immediately dims to about 60%. Only in Education edition. Windows 10 Pro boots up just fine at 100% brightness always.

This happens on both clean installs and upgrades. I've even upgraded a perfectly working Windows 10 Pro, which was always at 100% brightness, to Windows 10 Education by changing the product key - first boot into Education and right into screen dimmed at 60%!

I've never had Education edition installed before version 1703, so I don't know if this is due to Creator's Update or not.

Anybody else see this?
