MBP 17" santa rosa worked fine until this week when i try to boot it up nothing happens. no chime, no screen, but the sleep-light is on, the disc is spinning, it gets hot. if I close the lid the sleep-light is brighter. no warranty, apple claims logic-extension is only valid with chime. thinking of taking it to the local apple service provider but they charge $150/h just to look at it. how much do you think it will cost me? better to just buy a new one? how do i get access to the files on in? thanks!
