I have Win7 64bit and I have it set to sleep when I close the lid. If I open it a few hours after closing (in the evening after work) it wakes from sleep, however when I turn it on again in the morning it always resumes from hibernation. This implies it is waking in the night and then hibernating.
Why does it do this and how can I stop it so that it will be waking from sleep in the morning?
It always has 90%+ battery in the morning so its not like it is thinking it might not be able to sustain sleep much longer so hibernates to avoid losing work.
