XPS 13 9300 Not Able to Run Yahoo Videos When Plugged In

I've owned previous iterations of the Dell XPS 13, most recently, the 7390.  When I received the 9300, I get an error when trying to watch imbedded videos in Yahoo after it plays for a few seconds and then the screen goes dark and an error message says to refresh the browser.  Refreshing the browser does not resolve the error, but when I run the laptop on battery, the videos play without any errors.  This has only happened with the 9300, so I don't think it is a Yahoo setting issue.  If others have had this problem and were able to resolve it, please let me know how you did it.  Thanks.
