    Soooooo Cool the tool. Just one question, what is the unit of the *Consumption columns?

    @Justin_Huang: Jorge mentioned it is millijoules (but it might have been easy to miss).

    Wikipedia says that one joule is the amount of energy required to power one watt for one second.

    is there still a timing difference between the SC command and Net Start/stop. in other words, does the sc command return to a command prompt immediately whereas the net start/stop will wait for the activity to complete before returning to a command prompt? Is the answer applicable to all current supported versions of windows?

    @Tom: Yes, I believe you are correct. SC sends the start/stop command and exits immediately, while net start/stop waits for it to start/stop before returning. As far as I know this is consistent across all Windows versions.

    Great video! I followed along and found that a process with ID of "unknown" is consuming a lot of energy when the laptop is on battery and the screen is off. I am looking into this to try and troubleshoot why my Dell XPS 13 lost 13% of its battery last night while it should have been in sleep mode.

    Any ideas how to further dig into and identify what is showing as unknown? (my srumutil file is at https://www.dropbox.com/s/rzk81qlhcxtu041/srumutil.xlsx?dl=0 for reference)

    @bgilly: Please see the followup episode we did recently on System Power Report, in which we discuss what causes energy usage to be categorized as "unknown." Specifically, this question was addressed at around 9:40.
