Processor power management in game

Hello,
I would like to ask you about my problem in Window 7 professional 32bit.
I just reinstall it, and update it. But when I change Processor Power Management at 5% min and 80% max in power plan at both battery and plugin, so when I am in Windows everything works fine, but when I start a game in full-screen, this power plan will change to 100% for max and min, and stay like that.

I change it as Administrator. It is on laptop Toshiba A300D.
But before this last reinstall everything works fine. Really don't know where problem is.
Have you any ideas? Thanks.
