I didn't resolved it, only workaround. Try to install "hal" package from feisty. Remember, that hal from feisy have different dependencies (you have to remove hal-info package).
After installing old hal you wonn't be able to see battery state, until you plug and unplug again AC adapted. You can also (un)plug battery :) I don't own this laptop any more, so I can't help you much. This is probably bug in acpi or/and in hal. -- [gutsy] laptop keyboard hangs after (un)plug ac adapter, regression https://bugs.launchpad.net/bugs/152633 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
