Thank you very much for your help. Unfortunately none of your suggestions did work. I did press and hold the on/off button for more then 60 sec. and rebooted —> No effect! If I press Fn and F5 the machine just display ‘Hardware Airplane Mode’, nothing else happens… :(
After I upgraded to fedora 37 and rebooted the system, the airplane mode is on and can’t be switched off anymore. Meaning, now my Wi-fi is disconnected. I am using a Lenovo machine.
Any ideas how to fix this issue? Thanks in advance.
