Apple 1255 Bluetooth Keyboard Fix

The last time I replaced batteries in my Apple 1255 (three battery) keyboard it would not turn on. Turns out that it is a design flaw in the positive battery contact. The force of the battery falling down into the tubular compartment is sufficient to deform the contact. The remedy? Make a pea sized ball of aluminum foil and drop it into the tube. It’ll center on top of the contact due to a recess in the plastic around the contact. Put in batteries and replace the cap and ‘BINGO’ working keyboard. Happy I was about to throw it away and thought i’d google it.
