Videos stutter on Hp recommended battery mode

[Pranav93]

Hi. 
I am facing issues with video playback on my notebook's battery. The videos stutter and pixelate when running on laptop's battery. These videos run fine when i plug the ac power source into my notebook. When i manually change the power settings to High performance (on battery), the videos play fine. Clearly there is an issue with Hp recommended power saver mode. This has started occuring only recently.  Any help is appreciated. I hate to manually switch between the battery modes. 
Thanks

Hi @DavidSMP. 
This is a followup regarding the issue. The solution worked only for a while. I am back to square one and whats worse is my onboard brightness buttons dont work beyond a certain level. So when hit the button to increase the brightness, it goes up by one notch and thats it. No matter how many times i press it, nothing. The same goes with decreasing the brightnes. So..
1. My videos stutter just the way they did before.
2. I cant change screen's brightness. (Even the slider in Power Options doesn't work.So no change in screen brightness no matter what i do.)
