I've had Hibernate working on Windows 7 for quite a while... now I've noticed that when I try to resume from a Hibernate, instead of seeing "Resuming..." I see "Starting..." and then a message that Windows did not shut down properly.
What seems to be happening (to me) is that the Hibernate must not be completing properly, and instead of hibernating, the machine is just crashing. Then when I turn it back on, it does not recognize that it hibernated and attempts to start instead, then noticing that it did not shut down properly.
The only recent change I've made to my system is to add PGP Disk Encryption, although the problem did not start immediately after that, but a week or so later, so I don't think it's related.
Any ideas how to solve this?
