I understand I have made a thread already reffering to the buzzing on my MBP as well as my MBP damaged during shipping, but there is one more thing that I need to clarify. So a little background, ordered a refurbed MacBook Pro from the US site around July 25ish. The guy I talked to (salesman) said the MBP was brand new and there were no problems what so ever, just a minor software replacement. I picked up the laptop on my vacation in North Carolina (I live in Canada). Right when I opened it there was damage to the laptop, the little metal strap right above the button to open was damaged, like someone tried to pry it open. Called up AppleCare, no problem they will fix it. Something else happened a couple days ago. The buzzing from the machine, it is extremely faint when the power is plugged in, when running on battery it is louder. I havent notified AppleCare about this yet. They told me to send my MBP to the supply depot in Markham Ontario Canada with the damaged undercasing. Starting yesterday, I suddenly started randomly disconecting from the internet and MSN Messenger:mac 5.0 exits randomly. Does anyone know if this is common? When I bring my MacBook Pro to the supply depot, I want to ask them to replace the undercasing, logic board for the buzzing and hopefully everything will be resolved. As I say again, this is my first mac, hopefully it will not be my last mac. Thank you for your time, James.
