The Canonical team
has released Ubuntu 12.04 - a new long term support release. The
biggest new feature is the HUD, an addition to the traditional application menu system, where you can search for the actions you want to perform instead of having to hunt for them in menus. Unity overall has been improved, and I must say that even though this new release is simply
not at all ready for Asus ZenBooks, Unity runs perfectly well on it, and to my own shock and surprise, I'm slowly warming up to it. It's starting to make sense, it looks nice (especially after some custom tweaking), has become a lot more configurable, and it's really, really, really fast.

Try upgrading your kernel to the latest 3.3.x.
A lot of ACPI patches went to Linux 3.3 and it fixed some ACPI issues I had with my Lenovo ThinkPad T510. I've seen also that some other users reported success with 3.3 and ACPI on their ThinkPad laptops.

Please upgrade your kernel to the latest 3.3.x, test your suspend/hibernate and report back your results.
The latest kernel on Ubuntu 12.04 is 3.2.0 and this version seems to have some issues with ACPI on ThinkPads. At least from my experience.
Linux 3.3.x fixed all this for me.
