Laptop Screen Flickering
 

Hello All,
I am facing some problem with my HP laptop when on battery power has noticeable little flickers when changing from colour to colour.

Lets say the screen is predominantly white and I then switch to another window that is a darker colour it takes a around 3 seconds for the screen to adjust and show the correct colour however when on mains power this problem is solved.

I have:
Updated graphics drivers
Changed refresh rates

I also asked my problem with some tech support such as click4support & dell support, they provided to me some reliable solution..

If Any ideas is possible about my problem, please suggest to me....

I am waiting your reply....

Thank you..
