Hi all, I've had a 2010 MBP 13 for a week and it has frozen up three times. I did complete system updates early on. This happens at random times but usually when I've been using it a while e.g. web browsing. This is a hard freeze, so the mouse & keyboard have no effect, and putting the screen down does not put the laptop to sleep. Only holding down the power button has an effect. I have a week yet to return or exchange it at Best Buy, in which time I need to prove or disprove that it's defective. The Best Buy tech person said he'd need to run Tech Tools 5 overnight to determine whether it's a hardware defect. He also made it clear he wants to say it's a software issue caused by basically anything I may have installed. The only unusual thing that I've got installed is VirtualBox. My question for you all is, is there a free "burn in" program like Tech Tools 5 that I can use to determine where the problem may be? Or better yet, does OS/X keep a log file anywhere to record information about kernel crashes? Mind you there was never any message about a kernel panic. The machine just froze on 3 occasions. Thanks.
