The wireless on my HP 625 has suddenly stopped working. What can I do to turn it ON?
If you can't turn ON wireless from the button, then you can use HP Wireless Assistant for your HP 625 laptop. The application offers you the possibility to turn on wireless or Bluetooth feature. Alternatively, you should send the laptop to warranty service to repair the button.
Nope, hp wireless assistan DOESN'T do this for you... this answer will not work.
