Aeroplane mode always on / f11 key lid always on

[Andreas_Stam]

The problem occured all of a sudden after switching on my laptop as usual. The f11 key lid was on, thought might be accidentally pressed but unfortunately that was not the case. When I press it the light wont go off but it changes aeroplane mode on/off. But none of the wireless devices work (WiFi/Bluetooth). Actually they are not anywhere to be found on the device manager. Tried everything, downloading drivers from HP support site, still the devices are not found. Formatting is my last resort, so please help because it really frustrating.

Finally I figured it out! All you have to do is open the back side (one screw) and locate a square  chip next to the ram slots. It has 2 small wires, one for WiFi and the other for bluetooth communication. Take them off gently and then take off the ram from their slots (depends on how many you have installed). Put them all back as they were (wires and rams) and you 're done!

When I turned on my laptop, the light from the f11 key was off and all wireless communications were up and running!!! What a relief!
