In that case, the battery will last much longer while suspended to memory than with the computer running since the disk, display, peripherals, and even the CPU may be shut off, but it won't last forever since the memory still has to have power to retain state. Some apm's will wake up and convert a suspend-to-memory into suspend-to-disk, but this may or may not work properly depending on your setup. Other computers won't do this. If long-term suspends work under Windows but not under FreeBSD then that's a pretty likely scenario. Other computers just don't support long-term suspend-to-memory, and would fail just as badly under Windows. When you reboot after the suspend failure is you battery drained? (Or mostly drained, since once the computer shuts off the battery may recover slightly on its own.) > > -Arun -- Brian, the man from Babble-On . . . . bts@babbleon.org --------------------> Free Dmitry Sklyarov! <------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
