Or is this a desktop computer ?

It is a laptop

Laptop drivers contain a customization, which
identifies how the LCD panel is connected to the
GPU. A general purpose NVidia driver update, does
not contain this information. The NVidia software
should warn you that a laptop driver update is not
possible. You are supposed to get laptop driver
updates from the laptop maker.

Now, there are some sites (notebookreview.com)
which "hack" a standard driver, to support laptops.
So it is possible to modify the driver package
so it will work. And I have no idea what changes
are needed to make that happen.

There is a claim here, that NVidia has solved this
problem, and unknown to me, did so in 2008.
