by the way as you seem to be big experts. I have two question I would be pleased to ask you. I'm not sure this is the right way but I hope this won't disturb to much, otherwise please forgive me.
First: trying to open that fake demo this mornig, I had two crash, one after the other. I had to restart my machine by keeping the turn on button pressed. Is there anything I have to do after this happens. I mean, is there a maintainence I have to do like I did defrag in windows?
Second: I own a mbp. Does any of you guys hear a slight buzz coming from the down, right part of the screen when zou turn down your illumination. I heard it's a common problem, some say it might depend of the lcd inverter. The apple site nly talks about ths problem in 15" mabps, and I've been bringing my machine to the assistance already twice, they said they replaced the hole screen two different times but that slight buzz is still there. Any suggestion? thanks again!
