I just replaced the batteries after not having used the calculator for about a month. Now the buttons when pushed are very slow to respond. To get a response it takes several seconds of holding the button down

Hi,
If a piece foreign material such as a pencil lead is lodged in the I/O port of the calculator, it may create a short causing the calculator to respond slowly to key press entries.
If the piece of conductive material can be removed, it may restore the calculator to normal operating condition.
Let us know if you want something more else please accept the suggestion.
