CPU - Problems with my FE 21 M

[Musiker]

Hello! I bought my FE 21 M last Friday and got a problem now. When I'm doing nothing with my notebook, the cpu is going up and down ... in a range from 0 to 50%... like a slow heartbeat...
What can I do?

Thanks!

Hi Musiker and welcome to ClubVAIO.

Open Task Manager by pressing Ctrl+Alt+Del. Select 'Processes' and click on the letters "CPU". Scroll down to the bottom of the list and see what process(es) are using the 50% of your CPU power.

Let us know what is the culprit.
