Picked up an "as is for parts" ibook. It had some moisture stains between the plastic and metal shielding on both top and bottom of the base. Condensation or actual water had been inside the base unit. There is no green light when you push the power button on and the battery is totally dead, but it does boot with chimes.. I added ram, but it did not see it. I cleaned the ram slot with alcohol. That helped. I put a fresh install of O.S.9.2. I added an airport card. So it seems to be running fine now. 192mb of ram,and a 6gb harddrive.
