    Sleep Study not showing % of battery


    Hello! Does anybody know why the powercfg sleep study does not display any of the % of battery?


    Here's how it looks like:

    Sleep Study not showing % of battery 328cf7a9-83dc-4cd0-8051-446b305e09fe?upload=true.png

    The report was generated with powercfg /SleepStudy /output "C:\sleep_report.html".

    I'm running a brand-new ThinkPad T14s / AMD Ryzen 7 and I am trying to figure out why the modern standby is consuming a lot of battery. Since the percentages are missing, I wonder if the rest of the sleep report is accurate.



    It seems that the battery is properly detected by the system:

    Any help would be appreciated. Thanks!


    P.S. Using S3 sleep instead of modern standby is not an option either, as the audio driver fails to initialize after waking up, so I need to figure out what's draining the battery during S0 :

    :)

    Malware and sleep study possible interaction

    Hi,

    Thank you for posting your concern. Sleep Study is a Windows utility that only runs on systems that support InstantGo. You can determine if your hardware and software support InstantGo by entering
    powercfg /a into a Command Prompt window, and then looking to see if
    Standby (Connected)is included in the list of sleep states:

    Running Sleep Study requires Admin rights, Windows 8.1 or newer system, InstantGo support. You can refer to this
    link for more information about Sleep Study.

    Let us know how it goes.

    Microsoft Sleep Study Writing All Over C: Drive, an SSD

    Thank you for your help. I did as you suggested and found the Windows host process (Rundll32) was starting 7 copies of cm106eye.exe, a USB sound device utility, but nothing else, especially nothing relevant to the Microsoft Sleep Study continually
    writing 180,000 Bps to a file on my SSD. This computer does not have a battery, except in the UPS, and therefore, at this time, cannot use the outcome of a sleep study.
