    I've read through the number of posts on this and still cannot find a resolution to my issue.

    First, Surface Pro 3 with Windows 10. Computer is about 2 months old. Buggy little sucker but I do really like it. With that said, I'm seeing considerable battery drain in sleep mode.

    Each day, I leave the office and take the Surface off the docking station, connect my Type keyboard, close the lid, and stick it in my bag. The next day, when I get to work, I put the Surface back onto the dock. Many times, the battery is dead at this point, with minimal to no usage overnight.

    Today, I ran the sleep study analysis. For starters, here's the main culprit:

    Any thoughts?

    Just seems to be a win 10 thing. With both my sp3 and s3 if I don't turn them off at night then they will be dead come morning every single time.

    Could be hughlle and I agree turning it off is a workaround. I would hope that's not the long-term solution. Part of the benefit of having the tablet-style computer is the ability to quickly turn it on. Beyond that, I leave the office with apps open because I'm working on something I haven't finished. It's nice to have those apps ready to go when I start back up again.

    OK, you've run the sleep study, now go ahead in run the same command but replace -sleepstudy with -energy so we can see the actual program that is consuming the CPU time when it supposed to be in S0iX....

    You've been bit by the Windows 10 Audio Bug with the Realtek Drivers. Do you have an SD Card inserted? Any Firmware Updates pending?

    Doh! Realtek....

    No SD card inserted. How do I check for firmware updates? The Surface is set to automatic updates and the option to turn it off is greyed out (if that helps).

    As an aside, I checked the driver for Realtek through the device manager and it's currently up to date.

    Appreciate the links jnjroach.

    The first one talks specifically to a problem with an SD card. Beyond that, all it says is that Microsoft and Intel are working on a fix for something else. Not sure how this is relevant to my issue (please don't mistaken this for being rude...just not sure if this is my issue). I haven't ever connected an SD card to this Surface and just looked through the device manager for an SD card Realtek driver and am not finding anything.

    The second one is a lengthy discussion about issues with the SD card driver from Realtek. There's some discussion about the audio driver but I don't see any resolution to the problem in the discussion. Maybe I'm overlooking it.

    Do you have anything specific I could try? I do very much appreciate the help.

    Thanks.
    KC

    I disabled the Realtek audio device, then pulled the device from the base, attached the keyword and closed the lid for an hour. Drained 2%. Typically drains between 3 and 4%/hour overnight.
