To recover you could try pushing a paperclip into the reset hole on the back. This resets the calc but retains programs and data.

How can you stop it happening again? Making backups will help - it's explained in the manual and is quite simple but ask here if you have trouble. Backups on the calc survive an ON+APPS+ESC memory reset so even a major lock up won't result in too much being lost.

Lastly take care with the calc. You said you pulled it out the backpack and it had gone wrong? Well, remember that the USB port is not protected by the case so be careful if you normally stuff wet things like a coat or hat in without really thinking.

Do you think i can have a faulty unit?
It was always inside the case. It is weird thinking that it turned on and erased all the data by just accidentally clicking against the cover.
I was also thinking that in that week i made a trip, and the calculator was on my backpack all day, waking up and down, could the vibration be detrimental? I also thought about the idea of someone purposely erased it, but it doesn't make much sense...
Is there a way to save the backups in the pc? So i can write all my notes and programs again for once and for all.

Thanks for helping me ☺️

You can use the HP Prime Connectivity Kit to backup/restore your HP Prime program/configuration to your computer via USB.
