HP Prime reboots randomly

[jmtnezesc]

Hi, I have searched through the forum but I haven´t seen any solution to my problem. I bought my HP Prime NW280AA one month ago. I updated the firmware and the calculator works great but sometimes it reboots itself. The reboot doesn´t happen with any specific app or command. It´s just sometimes while working out for example linear equations,before pressing enter, the screen turns black and it turns on again but there is no trace of the work I had been doing. This reboot may happen 5 minutes after turning it on or half an hour later. It´s random. I hope someone can help me with this. Thank you.
