Screen dims and brightens every few seconds

Hello ELF,

One possible cause could be if you have "Adaptive Brightness" enabled. You could check and turn it off using an option in the tutorial below to see if this may be the issue.

In addition, check to make sure you have the latest graphics driver installed.

Another possible setting to look at is to see how many minutes you have set for turning off the display, and your "Dim display after" setting in Power Options. By default, the screen will dim 10 seconds before the specified turn off display after time. If you have the turn off display after time set to one minute, then it could dim on idle and brighten on activity like this.

Thank you!  I did what you suggested and no dice.  Its not just dimming though.  The slide bar that appears when I click the battery icon in the bottom right corner of the screen is randomly moving back and forth.  It looks like its cycling every few seconds between charging and not charging.

I shut down, took off the battery, plugged in the ac adapter, and rebooted.  Then I uninstalled software under device manager>battery, shutdown again, reinstalled the battery, and restarted.  The battery charged up to 68% then the screen started dimming again. Will try the fix suggested by the other respondent.  I'm also trying to charge fully, drain fully 3 times.  If you have other suggestions, feel free!  Thank you!
