    High cpu usage

    I am trying to solve an issue where I am experiencing an increase in usage of two cores of my cpu when the computer goes to sleep.

    When it does go to sleep the fan speed picks up to cool things off when normally nothing should be happening. When I move the mouse to wake the computer up the cpu usage drops and the fan slows down.

    I use a cpu usage tracker that shows the usage and when I wake the computer you can see the usage has dropped. I also use Process Hacker and can set it up to see what's running, but again when I move the mouse the process stops and I can no longer see what process was running.

    Any suggestions as to how to track this down?

    Running a diagnostic would be a good first step...

    Sleepmode troubleshooter:
    powercfg -ENERGY
    DRIVE IMAGING
    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.

    Build your own system; get everything you want and nothing you don't.

    Thanks for the link. It did point me in the right direction.
    As it turned out it was the Setpoint software for my keyboard and mouse.
    One problem with the Sleepmode trouble shooter in relation to my problem was that I needed it to run when the computer went to sleep, so I set the computer to sleep after one minute and I set the troubleshooter to run for 120 seconds. This seemed to run long enough to catch the problem.
    I ended up going back to an older version of the Setpoint software and all seems well again as long as I don't inadvertently upgrade the drivers again. :>)

    That's a bit unusual, nothing is really supposed to run, even in the S1 state. (at least in terms of processor usage)

    It's not actually sleeping, its just when the monitor shuts down.
