I'm interested to know what other users tend to see when running the "powercfg /sleepstudy" tool on their Surface Pro 3s (as per http://blogs.windows.com/windows/b/windowsexperience/archive/2014/06/26/sleep-study-diagnose-what-s-draining-your-battery-while-the-system-sleeps.aspx ). I'm finding that all my "InstantGo" sessions have a drain rate of between 1200 and 2200mW, which can correspond to between 10% and 20% of the battery drain in the 4 hours before the machine hibernates. Looking at the culprits, almost all the sessions show the following device running for the entire "sleep" period: USB xHCI Compliant Host Controller (\_SB.PCI0.XHC) Fx Device 100% 4:00:00 Is this expected? FWIW, I tend to leave the keyboard cover connected during sleep. Sometimes (when the drain is at the high end of the range), I also see the following: Intel(R) HD Graphics Family (\_SB.PCI0.GFX0) Fx Device 100% 4:00:00 Interestingly, during the first few days I had the SP3, the graphics driver was appearing in every session of the sleep study report. More recently, though, it has stopped appearing. Recently I've been leaving the Surface at the start screen rather than the Desktop, so this may be related - is there a recommendation about coming out of the Desktop before going to "sleep" I also never see anything in the "DRIPS histogram" - should I? What are other people seeing? On a related note, does anyone know if there is a way of changing the time before the machine hibernates? For me, 2 hours (or even 1 hour) would probably be fine - if I'm actively going from one office to another, then the "instant" resume is great, but if I'm at home, leaving the machine for a while, then 4 hours is overkill.

no need to apologise eepyaich That is definitely helpful. I was hoping that yourself or another MS community member had found a solution for both scenarios. I left my SP3 tablet on battery last night and that did not work.... came in this morning and it woke from Connected standby and not "hibernate". This is the first time I've read KB2835052 article but my understanding of https://support.microsoft.com/en-gb/kb/2835052 is that this simply controls the monitor and doesn't actual put the tablet to sleep. Also this article is indicating that it applies to Windows 8 and not Windows 8.1.... In case you were not aware one can confirm whether the tablet is actually going into sleep mode by looking in Event Viewer (System) ...I believe Kernel Power (Event 42) is an indicator of the tablet going to sleep....but it sounds like maybe you are not part of the IT dept. where you work.... anyway, cheers....we'll be looking deeper into our issues here. It may be GPO related. S

Just to be clear, are you talking about the machine going from connected standby to hibernate after 4 hours on battery, or just hibernating after 4 hours of unattended use even if on AC power? If the former, then it "just worked" for me (although I could believe that my IT department have followed the instructions in the blog you linked). If you're talking about the latter, then that isn't what I have. If the machine is docked on power, then I have it set to go to sleep after an hour of no use (where I needed to use some of the information in https://support.microsoft.com/en-gb/kb/2835052 to make sure that it did last an entire hour before sleeping when locked - the default seemed to be sleep after 30s when locked). When left on power, though, it doesn't hibernate at all - it'll stay in sleep until I come in next morning. Sorry I can't be more helpful.

What should "sleepstudy" show for a Surface Pro 3

To Eepyaich....

I'm having problems getting my SP3 with Win8.1 Enterprise to hibernate...

you wrote: "Personally, I've not had problems with the 4 hour transition to hibernate"
- we deploy Win8.1 to Surface Pro 3 using LiteTouch (MDT 2013) deployment
- we're using Group Policies (Balanced scheme) along with the following settings
: Specify the unattended hibernate timeout (4 hrs) for both AC and DC
- the setting shows up in my registry as expected:
HKLM\Software\Policies\Microsoft\Power\PowerSettings\9D7815A6-7EE4-497E-8888-515A05F02364

But my SP3 will not Hibernate after 4 hours of idle.

Further searches took me to the link for "Surface Pro 3 Hibernation Doesn’t Occur on Enterprise Install" (http://blogs.technet.com/b/askcore/archive/2014/11/05/surface-pro-3-hibernation-doesn-t-occur-on-enterprise-install.aspx) but my understanding is that this batch file is to do with transitions from one state to another (in other words when you go from the "connected" standby to hibernate and when to hibernate based on low battery level). is for Battery

So what did you do to get the 4 hr to Hibernate?
