Srange behavior on A2k keyboard.!

Oh no. A leaking battery. Remove it at once and clean the leaked acid. It can destroy your motherboard by eating up traces. It definitely is a probable cause to your problems. :-(

McBain: "Real acid?". :-)

Try cleaning it a q-tip, dipped in some isopropyl alcohol. Alternatively, get a new A2000 or just the motherboard. They are dirt cheap nowadays. Should be around from $20 to $50USD, depending on condition and expansions/accessories.
