I have had my MBP since Jan 2010, and have had problems with it ever since. I must have called Apple 50 times and they tried this and that but nothing helped. I have been to the Genius desk several times still nothing done. I called Apple again yesterday and requested a new laptop, no can do he said. He advised I take it back to the Genius desk and they would replace the logic board, so I took it there and he checked it in and told me they would also replace the battery. I sure hope this works or I will demand a new computer. Thank goodness for Apple Care, the bill was almost $600.00!
