Why can my 64-bit system only use 3.75 GB of RAM, when it has 4 GB and should support 8 GB?

I was recently going through my laptop specs when I stumbled upon a surprise. Apparently, according to my 64-bit Windows 7, I have 4 GB of RAM, but only 3.75 GB of it is actually usable.

I was planning on buying more RAM, but now I am not sure. I’m including a Flicker photo to prove it.

Can any one tell me what’s wrong with my laptop? It’s supposed to support a total of 8 GB of RAM.
