It will do this for a day at a time until interrupted. I find the backgroundtaskhost.exe on the top of the list using 50% of the cpu in the process display. I had to be quick because as soon as the display comes on the culprit quits. I started the resource monitor and looked for what was I first found it when I discovered my laptop fan running at high speed all the time.
I am experiencing a strange problem which manifests itself when the display is shut off by the power saving scheme.
