Do I have to replace my logic board
My 15" Macbook Pro (mid 2009 2.53 Ghz) is not booting up properly (it displays the apple logo and the progress wheel). Even safe boot is not always possible. In verbose mode I got the message "disk02: no such media present."
I downloaded a program called S.M.A.R.T. Reporter to do a health check on my HD. Everything seems fine. I was told that the problem is then probably the system bus. Does this mean that I have to replace the logic board altogether?
