    Excessive battery consumption while in Sleep mode


    Yesterday I placed my new SB with Performance Base (i7/1TB) in sleep mode for the first time, before it was always plugged, and noticed and excessive battery consumption, at the level of 10-20% per hour, with no applications running, no wifi and no notifications. Then I found "sleepstudy" so I run some test and reports and here are the results, as you can see the application PLM(5000): Microsoft.SurfaceHub_8wekyb3d8bbwe!App is consuming 100% of the CPU all the time, I have looked around in Google and I have not been able to find anything about, any hint on what this could be? How can I fix it?

    I searched What is PLM Phase on Microsoft Surface. Got a bunch of hits.

    One article say it is part of Connected Standby. This is that state that really never shuts off so you can get all those important notifications.

    So likely the app you identified is likely checking in, a lot.

    While an older thread this is may provide some help
