M6400 Covet- Rubber Screen Stop Problems

This is driving me crazy. The left rubber bumper on the keyboard deck of my m6400 keeps coming off. I called dell and they ended up replacing the entire deck just to replace this one little rubber piece and it just ended up coming off again. Is anyone else having this issue? I really don't want to call dell and set up a service call just to replace this one little piece. The last time I did the tech completely disassembled my laptop and it took him 3 reassembly attempts to get it to boot, but I'm worried the my screen will get cracked if I don't (I have the covet with the glass screen). Seems like a really bad design.

I haven't (on my E6400) had problems with the miniscule rubber bumpers on the palmrest but I did have problems with the top part of the display bezel rubbing against the palm rest. The fix, first suggested by another member, is some of these. I now have three along the top part of my display bezel, cut down to about half thickness after sticking them on. Everything is now rock-solid when I'm carrying the computer around. Dell should be doing this at the factory.
