Hey guys, this randomly started happening to me this week - Normally, I just put my computer to sleep, or let it go to sleep by itself. Lately however, it skips right past sleep and goes into hibernate. (You have to have experience with Vista/7 to understand this. Its different from XP as I'm sure you all know).
That's all fine and good I suppose, but here's the problem: It can't resume from hibernate. It starts up, flashes the startup animation for a second, then my monitor says "Frequency out of range". The HDD light is also on solid after this happens. The only thing to do is to turn it off and back on, and Windows offers to delete the restore file and start normally.
It has almost always done this with hibernate, but the issue with it skipping past sleep is new. Any ideas?
I'd go with waheed, try to disable hibernate then hopefully it will just go to sleep like normal. Do you know why the computer won't hibernate normally? Have you got some crazy hardware or partitioning scheme?
I did a little digging in the control panel, and decided to give Windows 7's new event recording tools a try. I found that there are many references to various drivers that are "affecting Windows' sleep ability". Some of them are nameless, but the one that makes the most sense is my graphics card driver. That would account for my monitor getting a signal outside the displayable range.
I'm still not entirely sure what happens, but I do know this now. - When it powers down, it attempts to enter S3 (sleep) mode, but for some reason the power is cut internally, then the computer restarts for about one second, then turns off completely.
