Both suspend to ram and suspend to disk work fine on my M1530, however whenever I resume from hibernation, I get a libnotify message: "Sleep Problem - Your computer failed to hibernate. Check the help file for common problems."
I don't know what is triggering this, even though the hibernate functions normally. I get 4 loud beeps prior to resuming from hibernation, I don't know what this means or if it is related. Any help would be appreciated.
