Wait, they don't do that any more, do they? There is a happy ending, but I've not seen the particular situation before and wanted to see if anybody had any input on this. Anyway, I have a Rev. A 1.83 Ghz Macbook Pro that went belly up tonight. After suffering a deep coma where it wouldn't come out of sleep (though the sleep light would change state when opened or closed), I forced it to shut down. When I tried to start it up, it only got as far as running the cd loading mechanism, no screen, no chime, with the sleep light very dimly lit. I'd only ever had it fail to even attempt booting once before when it was brand new, but all that had been necessary that time was to reset the SMC. But tonight, neither ⌘-⌥ p-r, nor that technique had any effect. Then I tried pulling the ram. After restarting it with no ram, the sleep indicator flashed rapidly and brightly, which I seem to recall having been the no-ram indicator, though I didn't find any indication on Apple's site about this. Once I reinserted the ram, it booted up. So I'm wondering if anybody has experienced such a scenario, or if you might know what reseating the ram does that is not handled by an SMC reset. Thanks.
