Hi, I posted a whie ago that I had problems with my old PowerBook G4 12". It broke ages ago and since then I had not tried to fix it and assumed it was the hard drive. However after taking it to the Apple store, I was told that the hard drive was not broken. The Apple Genius inspecting the PowerBook was unable to boot the laptop. Sometimes it would whir up and the disc would start but on other times it would not boot. The guys conclusion was that it was either a problem associated with the power button, startup etc., or a logic board problem. Is there any way I can get to the bottom of this by taking the laptop apart and checking the power button. I assume that fixing the power button is a relatively cheap process if this is causing the problem. Whereas, if it is the logic board, it is not worth the hassle and cost. I would really like to fix this as I have always like the 12" PowerBook and recently I have been contemplating purchasing a netbook, but if I could fix this, it will suit my needs perfectly. Thanks for any help or suggestions.
