Where is the wireless radio button on my T420?


Is there a way to switch the wireless radio on? I cannot find a button and have tried to activate this by pressing FN + F5 but to no avail.



The wireless radio switch is located on the right side of your laptop.



The green indicator shows that the wireless radio has been switched on.


This information can be found in T420 user guide, page 5.
