I can confirm this behaviour on my Thinkpad T42p 2373-KYG with Kubunutu 7.10 Gutsy Gibbon.
uname -a Linux ThinkpadT42p 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux Very annoying. Every 5th time after pulling the power cable, the system trys to suspend or hibernate and hangs on a black screen. To recover I had to press the power button until the system reboots. ** Changed in: ubuntu Status: New => Confirmed ** Changed in: ubuntu Assignee: (unassigned) => Ubuntu Kernel ACPI Team (ubuntu-kernel-acpi) -- Laptop suspends when power cord is pulled https://bugs.launchpad.net/bugs/157467 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
