I'm seeing this issue (or something *very* similar) on my MacBook 2,1 64bit karmic.
Log attached: 1) Close lid while on AC 2) open lid while on battery 3) Spontaneous suspend while entering password 4) Resume by pressing power button There are a couple of warning call traces in the log, but I suspect they should be processed in a separate issue. ** Attachment added: "Close lid while on AC - open lid while on battery - spontaneous suspend while entering password - resume by pressing power button" http://launchpadlibrarian.net/37708490/Close%20lid%20while%20on%20AC%20-%20open%20lid%20while%20on%20battery%20-%20spontaneous%20suspend%20while%20entering%20password%20-%20resume%20by%20pressing%20power%20button.txt -- Laptop automatically suspends right after resume if power cable was disconnected before resuming https://bugs.launchpad.net/bugs/492649 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
