Re-enforcing The Back-plate of The Dell XPS M1330

The keyboard on this lappie was a bit flaky, more like with flexing, with a lot of flexing... Specially around the upper left area, really annoying when you hit the Esc key.
So, what I did to add a little bit if stiff was pop it open and add a couple of threads of a somehow thick tape I had around.
The thing added a less than a milliliter thickness (or more like firmness) but it helped a lot.
