AFAIK "hybrid suspend" means that the OS prepares for hibernate (saving
memory & system state to disk) and then does suspend-to-RAM. The result
is that if you wake up the system before the battery runs out, it
behaves similar to suspend-to-RAM, but if you wake it up after it runs
out of battery it behaves as if you used suspend-to-disk/hibernate.
So your laptop doesn't wake up from suspend-to-ram and goes to
suspend-to-disk, as there is no need for that (and it would be extremely
error-prone).
And if you want a definitive answer about this, I suggest you contact
Matthew Garrett ("mjg59" on IRC) or another linux power management
guru... ;)
