ZZZ, I don't seem to experience that problem on my X60s. Given that I experienced bug 35174, perhaps it would be appropriate to file another bug with the details of your problem and hardware so that the information above does not confuse people.
Also, I want to note that my bug happens on both battery and AC, but only after I switch from one to another. -- ThinkPad X60 cannot Resume from Suspend https://launchpad.net/bugs/35174 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
