So recently I've been having this issue where my "A" and "W" keys tend to stick down to my membrane keyboard after pressing them. I assumed it was because of dirt so I removed the keys and swabbed around them with alcohol, yet they still stick down - they do come back up but as you can imagine it is very inconvenient and annoying and sometimes the key presses twice and makes it hard to type.
I've also swapped the A and W key for working keys and the working keys don't work, so I think it's something to do with the membrane underneath. I've unscrewed the keyboard and taken a look but everything appears fine and I'm really confused now.
If anybody has any suggestions as to how to fix this I would greatly appreciate it!
