my first question: Is there any other way I can turn the wireless on?
Maybe it’s possible;
Go to device manager -> WLan card -> properties -> Advanced tab
Here you should check if an option would be available which allows you to enable the WLan
Otherwise you should get in contact with an local ASP (authorized service partner).
I think it should be possible to ix this button since it’s only a plastic switch which should be replaceable….
Good luck
