First thing to do it opening it up and see if it *is* a battery issue.

bd (looks like a certain type of cordless phone battery, about as big 
around as a quarter and an inch or so long). More than likely you 
will find that on the ends (mainly the "-" end) there is a mold like 
substance. Now look around the surrounding area. Does it look like 
something was spilled onto the board in that area? That's corrosion 
damage to the board and its components due to the gas coming from the 
dead battery. It's possible to repair it, but sit down when you get 
the bill. Very time consuming and there's no guarantee it'll ever be 
right again. I recently gutted a Korg Poly 61 because of this. But 
that's ok, the poly61 sounds like shit and I needed a keybd/case 
donor for a synth I'm building anyway.
