On the energy report, there is a section for Sleep States capability. Which ones do you show as true? This might be used in conjunction with the times set for your different sleep/hibernate options.
Windows uses hybrid sleep as its default. There is an option under power settings, advanced settings to not allow hybrid sleep. If you continue to have problems you might try changing that for a while. You should also change some of the default timers so you know exactly when something should happen. Move the sleep back to 1 and hibernation to 2 or more hours if you have not already done that.
You might also try changing your entire power scheme to test. Start with High Performance to see if it works any better there.
I am not that...
