That seems enough. Without second patch AC adapter's status isn't updated on my laptop. AC status updates only if I run "acpi -a". I usually automated this with acpid. On my laptop only battery notifications are working fine. With second patch (and without first) everything works as it should. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
