My 1.33 GHz 12" iBook with Leopard may still work again. I powered it on with the old (Still working) battery, but not plugged into an adapter, and I heard it make sounds. It started humming, but then it beeped a couple times (I think 3) and the sleep light flashed on and off. How can I test the parts? I have a G3 Clamshell, a G4 iMac, and one of my siblings has one of the exact same model. I don't want to risk breaking any of them at all, though. How can I test the hard-drive or any other parts? This could save me over $200, so I would appreciate any help at all. Thanks! UPDATE: Also, I think the display might still work, but it could've been blown out. How do I hook it up to an external display before I turn it on? UPDATE 2: I heard that this is due to failed memory, and I removed the RAM stick and tried, but I still got the beeps.
