Well, but the important thing is whether you're seeing a message without "[unchanged]" in it after resuming. It's quite possible that in your use case (resuming in a different AC state) laptop_mode will be invoked in a way not to remain "unchanged". But I'm concerned with an entirely different use case: - suspend - do nothing at all, especially don't touch the AC cable - resume - wait a minute - not hear the annoying spinning drive any more For this use case, invoking laptop_mode force is necessary, as the drive doesn't remember the sleep timeouts and the kernel doesn't care about them at all. And I rather suspect that there may be other things that laptop_mode sets that are forgotten after a resume, but I may be wrong. Regards, -- Tomáš Janoušek, a.k.a. Pivník, a.k.a.
