Idle T460s CPU usage 115%

Finally got my beautiful machine. There is a problem though. After a couple of minutes after boot hot air starts to blow and Lenovo PM utulity shows CPU usage around 115% (!). Nothing has really been installed, apart from newest Avast and VLC. Couple of SAFE websites visited. Task Manager shows svchost using up 85% of CPU and there are several unknown to me services attached to this process. Certainly not something I have ever known.

 

Has anyone experienced this?

Oh, good question: Win 7.

 

I have found 25% CPU culprit -- Windows Update.

 

However CPU over 100% seems strange. I think though that the last Lenovo tools update has solved this, now it shows a reasonable usage and setting max cpu below 100% keeps it quiet.

I suggest you download procexp.exe from Microsoft. It gives more useful information that Task Manager and will help you find the process or service with high CPU usage.
