Which kind of problem, Don?

The battery compartment door getting too hot and partially melting.

When my original HP power adapter was functional, I could charge rechargeable batts overnight in the calculator and not worry about anything. But then that HP adapter got a short in one of its wires and stopped working. I got a USB charger on Ebay and that seemed to work fine overnight, but then I got a different USB charger and that one caused the melting. So I learned I couldn't trust the USB chargers anymore and bought a third party batt recharger (recommended by Dave Britten) and now I always use that.
