I had a problem with my Hp prime. After one year of use, it suddenly starts to present bugs. The bottom to the right and the enter bottom only work when they want. Some times I press to go to the right and it goes enter, or I press enter and it goes right. Also, the software is crazy! it press many buttons in the screen by itself and frozen often.
I have tried to re-instal (update) the firmware, after it is installed the calculator frozen in the image with "hp" and white background. I have tried to press 'on' and then it works.. but kept the same bugs, even though I have reset all my data on that. I have also tried to reset with the CFO method. But it never shows me the recovery mode, it only resets in the same way as symbol + on. Also tried the esc+ apps + on and it continues with the bugs.
I have tried to get support from HP but I can't find any way to contact them. Can someone help? maybe in how to talk to HP
This definitely is a hardware problem. I hope your machine is under warranty, because I assume you'll need a replacement or repair. Details on how to get it replaced depend on your local laws. Where I live (Netherlands), you can bring it back to the shop you bought it from.
