Most of the time I'm just carrying it up and down the stairs at my house.
There's your problem.
If that's a daily occurrence, the thing is going to break. Laptops made in the last 10 years are just junk. Leave it sitting on a desk and it'll be fine; treat it like a portable device and you're going to have a piece of broken garbage in a couple of years.
My work laptop is about the same age and put up with the same abuse, including me throwing it in my carry-on and slogging it around the airport and in planes multiple times per year. The only damage it suffered was a dead pixel on the screen.
