keyboard malfunctioning

[sarahbelle123]

I purchased the HP Laptop 15-da0xxx only a month ago. After about a week, the keyboard curser began moving all over while typing. If I don't catch it immediately and continue typing, The curser will move to another location, usually into the middle of another sentence, and what I typr either ends up in the middle of a sentence somewhere else on the page, or my entire document gets erased if I have backspaced (because I didn't know the curser had moved) PLEASE help me find a solution, I am way beyond frustrated. Thanks.

Still unable to find or fix problem. I don't know where to go from here.  I hate the idea of spending money to repair a brand new laptop. Thank you for your time and patience.
