There was an additional annoyance: 12.04 doesn't have hibernate available in menus by default. To run the hibernate process I had to launch pm-hibernate from the command line like so: sudo pm-hibernate I did that, it worked and everything came back on restart, but I didn't have to enter a password. I want the usual shutdown/suspend menus to include "hibernate" as an option, so I googled a bit and found this: http://askubuntu.com/questions/94754/how-to-enable-hibernation-in-12-04 The instruction there is to place this text... [Re-enable hibernate by default] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes ...into this file: /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla I did that, restarted, the menus then had "hibernate" as an option (both the menu in the upper right of the Unity desktop and the one that appers when I press the power button). I tested the hibernate menu option. It worked. When Ubuntu came back it made me log in to get back to my open windows, which is the correct behavior, I would say, but I guess pm-hibernate doesn't do that (I tried it again and the behavior was the same). Hibernate is a killer feature with this laptop because it his great battery life. It can suspend for days, but it can hibernate a lot longer. It comes back pretty quickly from hibernation, so I'm setting it to hibernate when I close the lid: (1) click the battery icon on the upper bar (2) choose power settings (3) set them how you want them For me, I chose "Hibernate" both for "When power is critically low" and "When the lid is closed." I also tested it by closing the lid, it hibernated and came back up (with password screen). So far, so good. Mike
