I do not have windows, but I suppose that the same would apply on windows. It seems to me indeed that when the computer is woken up, the operating system doesn't even have a clue (as I can see in the various logs in /var/log) that is gets started up from scratch instead of being woken up from S3 mode.
I upgraded my BIOS to A10 yesterday. The same exact bug remains. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617599 Title: Resume from suspend causes reboot, except if USB key is plugged in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1617599/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
