Dear Forumers, Some of you probably will remember my post a week ago, saying that my MBP DVD drive killed my OSX Installation DVD. So here is the conclusion of it, I took it authorised service center here in North Thailand. Waited for a week they sad they will change DVD drive and today it finally arrived. Around 11am they called me and said dude, we changed the drive the problem is still there cant install system. Your "Logic Board' is screwed, you have to wait at least 1 week for a new one. Now what is logic board? Is that main board? Is it possible for computer to still work with a broken mainboard? I mean I didnt damage it, I had kernell panic and tried to re-install OSX so how could that killed my MPB? I still could boot into disk utility and format the drive was just unable to copy files. To be honest my MBP is 3 months old, i took a good care of it. And I'm very very very dissapointed in apple computers now, expensive and damn un-reliable.
