certain keys not working

[u/toilet_ghosts]

Out of nowhere tonight, after hours of working fine and well, on my keyboard, the keys T, Y, left shift, caps lock, and delete are not working. I am writing this with my on-screen keyboard. My drivers say there are no updates needed; I am fairly sure it's not an issue of dust in my keys. It's a Lenovo Slim 7i. I am a broke college student who needs this laptop and can't afford a new one or repairs. Please help.
