This is really easy to do guys...so follow Joe Bleau guide on changing F11 Keyboard. He explains where to buy the right model etc.
I am in Hong Kong so i bought one from China it cost me 8 pounds...So follow joes instructions you can find him on google..couple of extra hints. Once you have it apart do clean the fan it takes a second and you will be amazed at whats in there. Be careful of the speakers they are delicate!
The light cable needs installing contacts facing up. Once its installed and tested put machine back together. You need to change the keyboard mapping to US and then you will find if you S1 and click keyboard there wil lbe a backlight option for 10 30 and 45 seconds and on...make your choice. It is worth the money. Ebay had about 100 last time i looked. Mine matches colour and sepc and looks great. I use it on flights alot and it is really good!
So thanks to Joe. took me aout 15 minutes in total to do.
To change mapping go to control panel regions and language clcik keyoard..download us english and you are done
