Cool, so it's way more durable than my Latitude 5290. I had my bottom cover screw inserts break when opening it. And the bottom panel is cracked in multiple locations. Also, recently had to reglue a display hinge, since it's just glued on the plastic top panel via a metal extension (it also broke the bezel which I had to plastic-weld to reinstall it). But I also use the display frame as a handrest so it was doomed to fail. Also, I had to reglue or replace most of the rubber housing parts. Here's my poor little laptop:

I kinda feel bad for this laptop coming into my aggressive hands.

I would recommend a Dell Latitude, but expect problems if you mistreat it like me. It isn't a T430 or T440p, which survive everything.

Edit: the green spot on the photo isn't a spot on the camera, it's a plastic-weld. Yes, it's all screwed with in weird ways, all by me.

Also, your laptop is in great condition, don't worry about it, you treat it above-average-ly, unlike me.
