Laptop repair for beginners

Before our trip I asked the readers for a suggestion if I should take a laptop with me.
Eventually I did. It proved a great help in storing and organizing photographs, accessing email, entertaining with a movie or two.
It went along to every country visited, via land or water, road or rail.
And it started showing signs of weariness. Firstly, the display started showing a green vertical band, then DVD device stopped reading some discs. Battery lasts only 10 minutes nowadays.
I was patient.
But when graphics card lost is ability to do the hardware acceleration, I've decided to take measures. Meaning, take it apart and look the problem in the face.
Now the laptop looks like this:

I wonder if there will be any leftover parts when I assemble it again.
