On your specific machine the action key F12 turns the wireless feature on or off.

Action keys are customized actions that are assigned to specific keys at the top of the keyboard. To use an action key, press and hold this key to activate the assigned function.

The action key feature is enabled at the factory. You can disable this feature in the BIOS and revert back to standard settings by pressing the fn key and one of the function keys to activate the assigned function.HP

The Action Key is not working – Peter Kihara Oct 8 '13 at 7:41

Well, the message is saying that some hardware key is causing the wireless to be disabled. There is no way Ubuntu can override this. The solution is to search for a wireless disable/enable key (often Fn+F5) and press it.
