I'm using Ubuntu 11.10 on my notebook as the main OS. How ever, I've been facing a serious problem: Every time I try to suspend it, or it just stays idle for a while, the computer shuts down, instead of suspending. It actually seems to be suspended, but when I press the button the awake it, it turns on, the open works are all lost.

How can i fix this?

P.s: On windows 7 the suspend / sleep resumes just fine.

  • I've updated the kernel to 3.2 still and hibernate or suspend is still not working.
  • SWAP is 1/4 of my RAM.

Is your swap space equal to or larger than the amount of RAM you have?

Your swap must be equal to or larger than your RAM in order to sleep / hibernate.

@KayakJim Are you sure that much swap is required to sleep. Hibernating is suspending to disk (to swap). Sleeping is suspending to RAM. –  Eliah Kagan Aug 4 at 2:57

Check swap space another to check is your settings in the power settings to see if setting is set to hibernation or sleep
