This says that it's BIOS that is forcing the device to be in low power mode. That means that the kernel rfkill drivers don't know how to handle WWAN rfkill on this laptop, and until that gets fixed you won't be able to use the card from coldboot under Linux :( The best thing you can do for now is maybe file a bug on bugzilla.kernel.org. The process will likely be similar to https://bugzilla.kernel.org/show_bug.cgi?id=47751 (though for thinkpad/lenovo instead of Sony) where you'll be asked to grab some BIOS information so kernel developers can debug it. I hope that helps... Dan _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
