If the battery leaked everywhere , then you have quite a mess to clean up. I detailed the procedure for neutralizing the battery goop elsewhere in this list.

My 240 did this when I first got it. Problem ended up being in the ribbon interconnects. They re IDC types so wires can work loose inside the connector housing

Scratching out the corrosion is a band aid fix. It *will* come back if not neutralized. The battery leaks out an alkaline: Potassium Hydroxide. This is a

You should scratch out the corrosion that lay over the traces and remove the ICs at the corroded area, place sockets instead and wire the bad traces. If

Oh well. I removed the battery and there was a fair amount of corrosion there. Nothing had been eaten through but the tell-tale brown discolouring was present.

It may take you a while but it definately worth it ! Clean all corrosion, replace ICs touched by the corrosion and chips that directly interfere with them,
