Hibernate and Sleep

Lenovo Ideapad Yoga 13 Windows 8 64 bit 8Gb Ram Intel i7 256Gb SSD I have started to hibernate the laptop when I'm not using it, instead of using sleep, to save battery power. When I was using sleep I had the wake timers enabled to allow the laptop to wake to run scheduled backup tasks. My understanding is that the laptop will not wake up from hibernate, but it does wake up from hibernate...
