Hey!


My problem is, I installed all the drivers what needed, and turned off energy saving at intel control center + on energy saving functions in control panel. BIOS is 1.18version and its not enable modify anything. Not even the rams or the Volts, nor the Cpu nor turbo boost.

But it seems there is an energy saving option missing becasue if I run a game it is bouncing fps from 130-30-130-30-130-30 it is becasue the processor changing its frequency to 700 from 3000 every second, and it says energy saver when on 700. I acivated on advanced power centric option with 100% power everything, but still nothing. This happens when i start a game , or just googleing. The cpu frequency is dropping every second as the Volts too.

How to turn of the whole energy saving function on the laptop, to avoid these Mhz bounces

Laptop: Acer travelmate 5760G
cpu: i5 2520M
