I use the unibody macbook pro. I haven't had any issue except the not sleeping when idle issue which, up until now, cannot be fixed. Today, I have another major problem, which seems to be the ethernet port. It stills connect me to the internet, but it's just that sometime it is not working. In istat pro, it will says that it still connected to the internet, but I wouldn't be able to open a web page or adium. I tried both Safari and Firefox, but get the same result. When I plugin the ethernet cable, it works for a few minutes, and then stop working, until I remove and plug it back in. So, right now I can only get internet connection for a few minutes. I ran apple hardware test, but it said "No problem found." Could this mean that the logic board is screw???? I'm living in Ottawa, Canada, and I don't have apple store nearby. I use the same cable with Sony Vaio, and it works perfectly.
