Hey guys, I have a macbook here that i'm trying to fix for a friend. The problem is it keeps shutting down about 3-4 minutes after it boots up. I checked the sleep settings and set them to "never", checked the battery and reset the PMU, then I ran the hardware test from the mac osx disc that came with it and the results said everything was fine. So now it has to be a software problem and I want to format and reinstall snow leopard but when I try to backup his photo's and documents to an external hdd, the computer turns itself off after a few minutes. When I ran the hardware test the machine stayed on for an hour plus so there's definitely a corrupt file or something wrong within the OS. My question is how can I backup his data without booting into the OS? Is there something like a bootable file manager I can load from a cd? If not, can I take the HDD out and put it in my windows pc and backup from there? All help and comments are appreciated Thanks very much.
