If a PC game says minimum requirments 2.0 gHZ processor will it not run at all on a 1.8gHZ?
It honestly depends. Sometimes other aspects of the system can make up for a slow processor. But for some games the minimum requirements mean that %26quot;This game won't make this particular computer explode.%26quot;
It's typically true with games that have 'bleeding edge' graphics and other such nonsense that anyone who doesn't touch themselves at night thinking about pixel shaders and has a pool of money cannot possibly meet the 'recommended' specs.
Sometimes it will work, sometimes it won't. But I'd lean more towards the won't. As sadly computer game manufacturers are a bit deceptive with their requirements. The minimum means it will run, not that it will run to the point where an enjoyable gaming experience can be had.

It will run, it may just have some speed issues (like your character moving too slowly to play the game effectively)
Changing video cards and processors in a laptop is just about impossible, one of the many reasons a desktop is soooo much better in my opinion, even in desktops you can't hardly change the processor without changing the motherboard, and you cant change a mobo in a laptop....
It'll run just fine, they always say you need more than you really do.
