PowerPC :: IBook Not Recognizing Charger - Not Getting Powered

I have an snow iBook G3 that I use everyday as my machine for doing schoolwork etc., so it is a very critical machine. The battery doesn't hold a charge anymore, so I just plug it in. No big deal. However, just a few hours ago the iBook started to not recognize it was plugged in. The prong has always been bent a bit, I think, and it always worked (before MagSafe type). The charger is beat up at the cord going into the power brick from the wall outlet, but it has always worked too and it seems to be a problem with the prong going into the computer. I have to hold it a very certain way for it to even detect power. So, the machine has NO way to get any power. I was thinking about taking it in to the Apple store to see if they could still get me a non-magsafe charger, but what if its something different then the charger?

The specs are as follows:
12 inch iBook
PowerPC G3
500 mhz
128 gb RAM

I have a Vista laptop I can use until its fixed, but I'd rather not use Windows. No speical prgrams or anything, I just really like Mac OSX. I have files on the iBook, too.
