RE: HP-21 malfunction
Connecting the charger with a bad battery pack (or no batter pack installed) is one of the quickest way to damage one of the HP-2X (Woodstock) or HP-3X (Spice) series calculators. Many collectors charge the batteries externally (or use non-rechargeable batteries) just to be on the safe side.
