I had the same problem, with Lenovo Thinkpad Twist and Saucy Salamander. It's kind of intermittent, I'm now trying to understand whether "echo LID0 | sudo tee /proc/acpi/wakeup" solves the problem.

If I suspend the machine by selecting "Suspend" in the system menu (Gear in the upper right corner), the suspend sequence get started but immediately after the sequence completing the machine wakes up again. So I am not able to suspend my computer. This is independent whether I am in laptop mode and operating the machine with a mouse or in tablet mode with the touch screen.
