A few weeks ago Techsnoop had the joy of trying to help someone enable their wireless internet on a Compaq CQ56.  This unit has a function key that theoretically turns the wireless service on or off.  However, holding down the function key and pressing the wireless key does nothing.

By accident (holding down function plus other keys and hitting the wireless key), I discovered that you need to hold down the function and alt key while tapping the wireless key. There is no documentation on this glitch.

So for everyone who is about to smash their CQ56, here is the answer.
Too bad it didn’t come from Compaq.
