How to reset HP Prime?

My HP Prime Graphical Calculator is locked in an endless calculation. It is running the Explorer app and prints a few lines of "Converting to exact approx symbolic matrix" then waits for key input. After pressing a key it prints another three such lines and waits.... forever. I am unable to break this loop. I have tried to reset using the button on the back side. And using On+Symb. But the calculator just continues running this loop after having rebooted. How can I break out of it?

Hi Kenneth,


Sad to hear you're having troubles with your HP Prime. Did you try removing the battery and replacing it? That should do the trick. If not: please contact your reseller for a possible replacement.
