Try removing the back up battery and the main batteries then hold in the reset button. Next, clean the battery leads with isopropyl alcohol and replace with fresh batteries.
Good Luck

Hi,
tried to switch on my HP50G after some weeks, but nothing happens. I
changed the batteries (main and backup battery) but the calculator
seems to be dead.
Some ideas how to reanimate that thing?
Regards, Thorsten
