So I had to send it my Macbook Pro (2009) into AppleCare due to some graphical issues and a non functional superdrive. I also had a dead pixel. I called Apple up and they were very helpful, it was collected the next day and returned within 3 working days, very good service! They replaced the Logic Board, Display and SuperDrive. It was actually a authorised repair service called Group 8 that did the repair, they were great. Not all was good though. Upon my first boot up the laptop froze in under 10 minutes. I had to do a force shutdown. I loaded it up again, it froze again in around 10 minutes. Then I reset the PRAM and ran a Disk Permissions Repair, once again it froze, this time mid way. After the 3rd freeze I decided to try one more time. This time it finished the repair and several other maintenance tools. Its now been running for around 90 minutes and hasn't suffered any freezing. Its also definitely a lot more snappy. I also suffered a glitch which said "Your computer's clock is set to a date before Jan 1, 2008. This may cause some applications to behave erratically. To set the clock manually, open Date & Time preferences. " This was after the third freeze but I fixed it and it seems to be okay now. Do you guys think its fine? I'm guess I'm looking for some reassurance, has anybody else had a couple of freezes with a new logic board? Any comments are welcome. Oh and also, I'm running Snow Leopard. I have Lion on my iMac and really dislike it, hence not putting it on my Macbook.
