Same problem here on Sony Vaio VGN-FE31M. Probably this bug is related to https://bugs.launchpad.net/bugs/213128.
Temporary workaround. Create the files: /etc/acpi/ac.d/power-switch.sh containing: hal-set-property --udi `hal-find-by-capability --capability ac_adapter` --key ac_adapter.present --bool true /etc/acpi/battery.d/power-switch.sh containing: hal-set-property --udi `hal-find-by-capability --capability ac_adapter` --key ac_adapter.present --bool false Hope it helps. -- AC adapter status don't change when unpluged it https://bugs.launchpad.net/bugs/254603 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
