Did you press the reset button? (in the back, with a paper clip).
Also try plugging it into the USB.
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?
