I've been using my HP Prime for about a month now. And, suddenly while I was trying to use the calculator, the screen froze and showed the x^2 +y^2 with a circle and shut down. I can't get it to open and I have tried pressing the reset button, the reset button and the SYMB button at the same time. And the computer can't detect the calculator either.
It doesn't seem to charge either.
I saw other people had troubles with the x^2 screen, but it to do with updating and I haven't done that.
Thanks for any help!

They are a number of things that you could try.
Assuming that you do not have any important data in memory, the easiest way might be to erase the memory.
press and hold the C, F and O keys. Press and release the rest button.
This will drop you in the diagnostic screen.
PRess 4: FLS utilities and then 3 ENTER to format the file system.
Once complete, reset the calculator and see if it works better.

You are saying that the screen does not even turn on?
If yes, then try the following
Remove the battery, Press and hold the Symb key, then connect the USB cable (itself connected to power, computer...)
Does this turn the screen ON? If yes, then the calc seems to be working. if no, the then there is most likely a HW problem.
if yes, then try again to remove the battery/connect USB, but wit the C/F/O keys pressed this time and try to format C: drive as in my previous answer and see if it boots.
If this does not work, try again the USB+SYmb and do a system update.
