the problem is that the brightness sometimes increases and decreases from 60% to 80% and back within few seconds, with no reason.
First the problem only occured in Microsoft solitaire games, but now I'm facing the problem in common use like browsing.

As per the query we understood that you facing issue with brightness in your Lenovo Z710 laptop.
Try to reinstall the graphic driver and check for the issue, try to perform a color calibration by go to control panel select display option under display option select color calibration and follow the onscreen calibration. You can also check changing the power plans in the energy management.
