I have been looking for the answer for the better part of a day now. Have installed Ubuntu 12.04 LST on said computer, ethernet connection is fine, but cant for the life of me get wifi to work.
Using sudo rfkill list all, I see it is hardblocked, but bios doesnt give me an option to turn wifi on on boot up, and i get no response from the button on the side of the laptop. Everything else is running perfectly.
