I've been having problems with windows 7 waking from sleep after one minute or so on my laptop. I also have ArchLinux installed on this computer. A while back I tried a registry tweak to get windows to use UTC so it would play nice with Linux. The registry tweak didn't seem to work and my windows clock was always wrong. Today I deleted the registry entry that I added, and the problem with sleeping seemed to go away.
Can anyone make sense of this?
Edit: I'm specifically wondering about the sleep problem, not so much about the clock.
The registry entry I added was:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001
Thanks for the reply. This is definitely helpful. I was actually wondering more about the sleep problem (reflected in my edit above) but I do appreciate the quick response. – xthrd – 2012-03-26T18:11:19.087
What threw me off the track of attempting to fix the sleep issue, was this line "Today I deleted the registry entry that I added, and the problem with sleeping seemed to go away." Microsoft says it could be Media Center's fault... http://support.microsoft.com/kb/979878 but THIS article points out not only could it be your network card, but the command to find out what woke it up. powercfg -lastwake http://www.cravingtech.com/fix-windows-vista7-sleep-mode-from-waking-up-by-itself.html

Wake History Count - 1 Wake History [0] Wake Source Count - 0
The system log was also devoid of any helpful information, as was the powercfg energy diagnostic. But it's working fine now so I guess I just chalk it up to luck. – xthrd – 2012-03-27T21:26:00.897
