HP Prime does not work anymore HELP!

[cyrille de brébisson]

Hello,

I am sorry to hear that you are having issues... Let us try to get you out of your troubles...

1: you said that the screen is working (white, luminescent), so this means that the power is ok and that some part of the system is OK also...
2: What caused the "break"/"Stop working"? did you do something to it (knowing how it append can highly help in fixing it)...
3: have you tried going into the boot loader?
Press and HOLD the symb key, then press on the reset button at the back. it should reboot, and show the HP logo with a "HP Prime recovery mode" message on top.
If you can get there, then you are 'saved'. Start the con kit, tell it to check for updates, connect the calculator to the PC using USB and it should ask you if you want to 'update', say yes and your calculator should be back to normal.
