And when I try to just suspend, I still hear the disk spinning after a long time. And when I ry to come out of it by hitting a key on the keyboard or the power button, it does nothing. Only pushing the power button for a while makes it shut down completely. I think this started when I updated to 12.04. My battery is also having some issues staying locked and connected, but it may be unrelated. Any ideas how to get it to suspend or shut down without pushing the power button for a while?
