i made my own power supply wall plugin cable for my ibook g3 power adapter. Its from a printer, computer boots fine, but with only one problem it wont charge the battery is this because i only have the two prongs connected to power while the weird silver circle doesnt have any power"

The 3rd prong is actually a ground.
Generally, you won't need it in terms of powering the device, but the computer may not charge unless it detects a ground?
I'd like to hear from somebody who lives in an old house/apt who only has 2-prong outlets and what their experience is.
