So after installing the Dec firmware, like many of you, I am having major hibernation issues. It doesn't seem to ever hibernate and when I come back to my SP2 after an hour or so it is VERY hot and the battery is drained. This is one of the many issues I've had with the SP2 but I want to make sure I've explored all options before I throw in the towel and exchange it for a Yoga Pro 2. Can I downgrade to the previous firmware without doing a complete reinstall? For some reason I only have 1 restore point which is well after the upgrade. So that's no help. Do I have any other options? Thanks!
