furthremore on an attempted SMC reset (which I've been told might be a solution) the light never blinks whilst I perform the proper keystrokes. (I've heard different things about how to know if the reset works; that I see no blink makes me think it hasn't reset)


please advise


thanks

It's a beta - file bugs and see what comes back.
