If you're like me, you have an issue where the click buttons on the Dell Chromebook 11 3120 doesn't go all the way down unless it's at a certain angle. I however figured out a fix that worked for me.

To put it simply, the metal bracket where the mouse buttons are was bent. The metal bracket is question is this:

Simply unscrew it, and then bend it back straight (It's actually a pretty tough bracket, so it may take some muscle)

If it went well, you should notice that the clicks won't get stuck anymore.
