I bought my laptop used and it has been working great for about a month, but this afternoon some of the keys stopped working. I uninstalled the drivers and the device, reset my laptop, but the keys still don't work I read on multiple forums that it could be the cable rubbing against some metal which causes interference.

After testing the keyboard on keyboardtester.com I got this result: https://1drv.ms/u/s!AtCKIFJVywkDuQ05PLmZekvMU0Qb the green and dark gray keys are working, the others are not. Does this indicate that a couple lanes on the cable are not working? Thanks in advance

To find out what the issue is with the keyboard, re-seat the cables. If that does not work you can replace the keyboard, most are $20 or so on eBay.
With the way the bad letters are in noticeable stripes it may be a bad cable connection. Either way, you will need to re-seat or replace the keyboard.
