Hello. On my Laptop i had the issue of certain keys not working. But then it got worse with time. A few more keys stopped working. While they were not essential it was still annoying as most of keys in the numpad could not be used. When the delete key also stopped working , that was it. Looking for solution i came across a thread where this link https://support.hp.com/us-en/product/HP-OMEN-15-Notebook/7281265/model/7468071/document/c03738933#Ab... was posted as a solution. I did all the steps and as weird as this sounds, most of the defective keys were suddenly working again. With exception of keys 7,8,9 and +. Also the arrow keys left and right do work sometimes other times they don´t. I´d appreciate if someone could point me to a way of fixing the issue once and for all.
