cableghost Posted May 8, 2011 Posted May 8, 2011 I just built a new system, Win7 SP1, and the **** thing will not stay hibernated or asleep. It wakes at around the same time each morning.I have turned off WOL in the BIOS, I have disabled waking for every device which had the option, and I have turned off any software updating services, that I know of.When checking Event Viewer, there's no software or hardware events. The first event, shown below, seems to be the PC checking the time.Could this actually be waking my PC?Log Name: SystemSource: Microsoft-Windows-Kernel-GeneralDate: 5/8/2011 4:16:16 AMEvent ID: 1Task Category: NoneLevel: InformationKeywords: Time...The system time has changed to 2011-05-08T09:16:16.500000000Z from 2011-05-08T04:41:08.083033400Z.Event Xml:<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Microsoft-Windows-Kernel-General" Guid="{A68CA8B7-004F-D7B6-A698-07E2DE0F1F5D}" /> ... </System> <EventData> <Data Name="NewTime">2011-05-08T09:16:16.500000000Z</Data> <Data Name="OldTime">2011-05-08T04:41:08.083033400Z</Data> </EventData></Event>BTW, I have ruled out our cat stepping on the power button, and as mentioned, I have wake by USB/keyboard/mouse disabled.
jaclaz Posted May 8, 2011 Posted May 8, 2011 GUID {A68CA8B7-004F-D7B6-A698-07E2DE0F1F5D belongs to Windows time servicehttp://technet.microsoft.com/en-us/library/cc773013(WS.10).aspxhttp://blogs.msdn.com/b/w32time/How often it synchronizes depends form settings, I seem to remember that default is once a week (unless the PC is in a domain, etc.) check the Registry, values should be remained the same:http://support.microsoft.com/kb/223184/en-usjaclaz
allen2 Posted May 8, 2011 Posted May 8, 2011 Some bios also can power on the computer at preset times but you might have already checked this.

Though the keys are different in Win7, I did notice that my Time module did have Notify me when time changes enabled. I'll disable and get it a try.Some bios also can power on the computer at preset times but you might have already checked this.Not certain what I would be looking for...what might this be, other than WOL option?

cableghost Posted May 15, 2011 Author Posted May 15, 2011 I determined it was the Time change functionality; it was waking my PC to Notify me that there had been an update to the time.
