Loose Laptop Screen

I have a Dell Latitude D630 that I purchased a few years ago to use for my MBA. Over the past couple of months, the screen has started to wobble - when I open it up, the screen part of the clamshell wobbles. I remember this being a problem with a lot of older laptops - years ago. But this is the only one that has done it to me recently...

It turns out this is quite an easy problem to solve!

There are four screw-holes that need to be tightened - just snug, not tight - don't strip these.

...and problem solved!
