If you are having a double keystroke issue such as pressing a and getting aa or e and getting ee then follow this link which seemed to help with my issue. This was also after getting a replacement keyboard from customer service and the new device having the same issue. https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/Keyboard-has-a-tendency-to-repeat-keystrokes-maaking/td-p/2650729



Hopefully this helps someone as it did me since this seems to be a common issue. Good luck!!
