I had this laptop for around 6 years, and lately my keys have been failing to work properly, particularly 7-0 on the num strip, 0, 6, and 2 on the num pad, and the letter R. I tried hard resetting, taking the battery out, and updating my software and drivers, but it's seems like it's a hardware issue. What are the proper steps to take with this now, I'm sort of new to this whole thing.
