To dandelion:
All BS aside, you got screwed dude! My advice to you is to salvage the good parts from that Amiga 4000 and keep them as spare parts. Then buy yourself another Amiga 4000, only this time making sure that you first ask all kinds of questions about the computer. Or you could buy another Amiga 4000 motherboard from eBay, I see them all the time listed. Make sure that before bidding on an Amiga 4000 motherboard that you ask the seller questions like "Is the battery or surrounding area on the motherboard corroded or discolored". Also ask the seller to email you a picture of the battery area of the motherboard. Battery acid corrosion is like a cancer, once it starts it can not be stopped. You WILL eventually have problems with that corroded A4000 motherboard, so REPLACE IT! :-o
