I have a similar problem on a Lenovo ThinkPad T400s. If I unplug the machine while it's asleep, it just freezes outright on resume. I can see the login screen, but the mouse and keyboard don't function, and the "I" bar (text entry cursor) is not blinking per usual.
The resolution described in comment #47 seems to fix the issue for me (though I'm not exactly sure what it does). I'm running a fully up to date copy of Karmic. ** Summary changed: - Computer suspends immediately after resuming if power is unplugged while suspended + Computer suspends or freezes immediately after resuming if power is unplugged while suspended -- Computer suspends or freezes immediately after resuming if power is unplugged while suspended https://bugs.launchpad.net/bugs/425411 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
