As promised, here the full debug output of hal. Note 1: that as the last thing I unplugged the laptop from AC (and maybe even plugged it in).
Note 2: I've been playing videos draining the full battery while traveling, so there might be warnings about that and low battery. Let me know if I can help anything else (maybe do this again while AC always plugged in or so) ** Attachment added: "HAL debug output" http://librarian.launchpad.net/4223555/hal.log -- false hibernation warning https://launchpad.net/bugs/51225 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
