Honestly OP, weird keyboard issues, especially on a laptop are very often hardware failures.
As for driver downloading software, Linux works far different from Windows in this sense. Linux drivers usually come packaged with the kernel and are otherwise downloaded through the repository of your relevant distribution, so you don't need any third party software.
You could boot into the bios and test the keys there. If they still don't work then its a hardware issue. Do you know how to get into the bios?
Edit: Also OP, if you do have issues in the future, please post them on https://lemmy.world/c/techsupport as this isn't really the right community.
