The "allow device to wake up computer" is already set to "off" in mouse, keyboard and other USB devices, together with any bios settings related to wake up. Yet still, at least once a week my computer is on in the morning, after i set it to Hibernate the night before. Sometimes it even power cycles straight away after i tried to turn it of. Same today, when i was was out of the house for a few hours, and it decided to magically turn itself on, run windows update and restart. I have to power it down and turn of the the power on the power-strip each night. My work laptop has the same issue, except it does not care about the power strip switch and discharges the battery overnight instead!
