T731 CPU fan work on battary

Postby Pavel » Mon Jan 30, 2012 19:15

I have a new T731. Its a good comp. Thanks!
But when its working on a battery, CPU fan doesn't stop at all, and continue to work on a low speed. Even on the "Passive" cooling police in the powersave power paln. The CPU and another components are still cool. CPU load ~1% during long time (comp not load any tasks).

CPU fan doesn't stop at any mode!!!

Is it right? Is it a correct behavior? CPU fan can use up to 1-2W - it is about 10-15% of a battery working time .... its not good.
Is there any sollution of this?
