Dell Inspiron 15 keyboard replacement help

Hey there! 🙂

I’ve run into this weird keyboard glitch, and honestly, I haven't been able to find a single decent fix for it online yet.
My laptop is just under two years old, but over the last few months, the keyboard has basically started acting possessed.
It all started when the "@" symbol would just randomly stop working, but now it’s completely dead, so I’m stuck having to copy and paste it from somewhere else every single time!
Then, things got even weirder because certain keys in that top row—you know, like Q, E, U, I, and O—started acting super flaky, and sometimes even the "A" key decides to just quit on me entirely... or maybe it's other keys too, who knows, it's getting hard to tell.
The way it breaks is so strange; one minute a bunch of keys just stop responding out of nowhere, and then suddenly they'll start working again after an hour or two, or if I just mash them like crazy for a bit... it's driving me nuts!

I've already tried reinstalling all the drivers and poked around at a few other settings, but nothing seems to stick. I'm starting to think it's a hardware issue deep inside the machine, but I'm really not sure what's actually going on.

Any bright ideas or suggestions?

If you’ve had it for less than two years, I’m guessing it’s still under warranty, so honestly? Just get your butt down to the service center ASAP!
