English for Tango

Lately the itch to get an English layout keyboard for Tango has been going back and forth in my head...

I guess I'll cough up the 85 U$S they are asking for it here in Bs As, as I'm getting angrier and more angrier with the one with Spanish layout it currently has.

Being Googling for pdfs, blogs, instructions, youtube videos on how to do this for this particular model; on the Compaq website haven't being able to find anything more complex than adding RAM...
