If you want to read up on this just search for my username. I took my Powerbook back to the mac store since they told me the logic board was causing it to get hot and go to sleep. The "genius" told me he had to see this happen to take it. I ran some stuff to get the CPU usage up and it was getting hot. He said this was normal and that it was probably just getting too hot and going to sleep. He suggested getting one of those lap cooler things or to prop it up while its on my desk. I asked him about the previous diagnosis and he said that the trick the guy used was for the older powerbooks. He said I could call and have a box send to me and ship it from my home. Should I just get one of those coolers and see if it goes away or should I just ship it out to Apple. Thanks!
