i have the exact same issue with the exact same keys, so i'm inclined to suspect it's not water damage; also because i didn't spill a drop. my keyboard has italian layout, so typed characters don't match with those in the video, but key positions are the same. so maybe it's just a coincidence, maybe it's due to some wiring/welding pattern. these are all keys coupling i spotted so far; they "work" both ways: F1 w F2 e F8 > o \ q r 5 u 6 p ' i ì - + num9 num6 i'm going to double check looking for drivers issues or debris below keys, then i'll concede and replace the keyboard. thank you for the video!
I'm sitting here with a half-disassembled laptop. You really could've stated how many screws you removed in total so I know whether I should look for more.
