I have a powerbook 12' 867 mghz, I know I would rather have a new one, but not ready to give up on this old gal yet! Anywhoo I thought the logic board was fried but after letting the powerbook "rest" I came back months later and sometimes it will boot but as soon as I try to do anything it freezes, so maybe the harddrive is fried? How do you get it to ignore the internal drive so it will boot from an external? I guess I could just pull out the internal one? ideas? Thanks!
