I think my old water-damaged G4 iBook could work again! How to diagnose/fix/test it?

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.

It does sound like a memory issue. Does your ibook have a VGA port on it? If it does you can hook up a display via that, Although if i remember correctly, some of them only had a special port that you had to put a card into.(maybe those were the powerbooks?)

This is what you need to connect your ibook to a VGA external monitor.

Thanks! I've decided I'm getting a new one and trying out the hard-drive adaptor just for the price of Leopard.
