doveman Posted June 26, 2012 Share Posted June 26, 2012 (edited) I have setup an HTPC running MediaPortal with Windows 7 x32 Ultimate, which is set to go to standby after 30 minutes. Sometimes it does and sometimes it doesn't and I can't figure out any rhyme or reason as to why, so I'd be grateful for some assistance with tracking down what the problem is.As you'll know, Windows is pretty terrible regarding providing any information as to what might be preventing standby. I've checked no devices are set to prevent it (of course, if they were it wouldn't work sometimes anyway). If I do powercfg - requests it shows:C:\Users\MediaPortal>powercfg -requestsDISPLAY: None. SYSTEM:[DRIVER] \FileSystem\srvnetAn active remote client has recently sent requests to this machine. AWAYMODE: None.but I've used the tweak to set "Enable standby with remote opens" in Power Options and powercfg -requestsoverride shows:C:\Users\MediaPortal>powercfg -requestsoverride[SERVICE] [PROCESS] [DRIVER]\FileSystem\srvnet SYSTEMI had LogMeIn installed, which has an option at install to "Prevent standby when AC power is available". I'm not sure how it enforces that, but I unticked it anyway so that shouldn't have been a problem but I've completely uninstalled it now anyway, due to problems with it's mirror driver disabling Aero and not re-enabling it after disconnecting. I now have TightVNC installed which uses a mirror driver but that does re-enable Aero when disconnected. I don't think that can be anything to do with the Standby problem anyway.

jaclaz Posted June 26, 2012 Share Posted June 26, 2012 As you'll know, Windows is pretty terrible regarding providing any information as to what might be preventing standby. But maybe you can find what prevented it (past tense) checking in the event logs? jaclaz Link to comment Share on other sites More sharing options...
doveman Posted June 26, 2012 Author Share Posted June 26, 2012 But maybe you can find what prevented it (past tense) checking in the event logs? Would be nice if we could, but no there's nothing useful in there. I looked into that when I had a problem with Standby a while ago on a different PC and it wasn't of any help then either!

MagicAndre1981 Posted June 26, 2012 Share Posted June 26, 2012 Check this thread:Trace Windows 7 boot/shutdown/hibernate/standby/resume issuesxbootmgr only shows why it it slow, not why it sometimes doesn't work. Link to comment Share on other sites More sharing options...
doveman Posted June 26, 2012 Author Share Posted June 26, 2012 I've never found it much use in the past and I can't see anything obvious in it now but I've attached the powercfg -energy report in case something stands out that I'm overlooking.energy-report.html Link to comment Share on other sites More sharing options...
doveman Posted June 27, 2012 Author Share Posted June 27, 2012 I've been testing today with hibernate disabled (powercfg -h off) and Standby seems to work OK like that (I'll give it a couple of days to be sure though).I previously found that Standby doesn't work with hibernate enabled if the C: partition isn't marked Active, due to some internal Windows requirement for the partition holding the hibernate file to be the Active one, but this isn't the problem now as the C: partition is marked Active. Anyway, with that problem Standby never worked, whereas now it's an intermittent problem. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 27, 2012 Share Posted June 27, 2012 turn off the Hybrid mode:http://www.howtogeek.com/howto/windows-vista/disable-hybrid-sleep-mode/Does this solve it? Link to comment Share on other sites More sharing options...
doveman Posted June 27, 2012 Author Share Posted June 27, 2012 (edited) I'll certainly test it to see, although I only want to use Hibernate for the Hybrid function (i.e. restore in the event of a power-cut) so if it's necessary to disable Hybrid I might as well just disable Hibernate completely.EDIT: Hmm, I don't know if this is normal or could be the cause of the problem, but when I look at the Security tab for hiberfil.sys it shows "The requested security information is either unavailable or can't be displayed". Mind you it says the same on my other system, although I don't use standby or hibernate on there much (other than manual standby) so there could be a problem with that as well for all I know! I am logged in with an Administrator account on both systems. Edited June 27, 2012 by doveman Link to comment Share on other sites More sharing options...
doveman Posted June 28, 2012 Author Share Posted June 28, 2012 OK, it seems to work with Hybrid disabled. So is there anything else we can do to work out why it doesn't work with Hybrid enabled (i.e. when it's writing to the Hibernate file on standby)?

MagicAndre1981 Posted June 29, 2012 Share Posted June 29, 2012 it writes the hibernation file at the beginning of standby. If the power is lost Windows can resume from this hibernation file. Link to comment Share on other sites More sharing options...
doveman Posted June 29, 2012 Author Share Posted June 29, 2012 eh? I know that. Not sure what you're trying to tell me there. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 29, 2012 Share Posted June 29, 2012 ? you asked it in your previous post? With hybrid disabled you can select hibernation from shutdown options. Does this work? Link to comment Share on other sites More sharing options...
doveman Posted June 29, 2012 Author Share Posted June 29, 2012 It seems there's a bit of confusion here. I asked "So is there anything else we can do to work out why it doesn't work with Hybrid enabled " and your reply just explains how, when using Hybrid mode, it writes the hibernation file at the beginning of standby, which I thought my post #9 showed I already knew, but perhaps it wasn't clear.I'll check whether manual Hibernation works then. In the past when I've had problems with standby or hibernate not working automatically, I've always found them to work when triggered manually so I expect it to work but I'll check to be sure.

doveman Posted June 30, 2012 Author Share Posted June 30, 2012 OK, I tested sending it into Hibernate manually last night and that worked fine (as did the resume this morning). Link to comment Share on other sites More sharing options...
