Leonvo P40 yoga enery saving options



my Leonovo P40 yoga is sometimes switching in the energy saving mode.

It changes to the mode with an unregular pattern. Sometimes 10 seconds after a reboot sometimes every 30 seconds after doing nothing and sometimes after more than 20 minutes ...


What can i do ?!?  


I changed the energy saving options but the Ultrabook don´t care ...
