is there no hope?, exactly what upgrads can be done to a laptop?
You can add 2D graphics and very basic 3D via an add-in PCMCIA card, but that won't be an upgrade, nowadays only useable as a second/third monitor solution for 2D work.
As has been mentioned you can increase CPU, RAM, and HDD.
You can also increase graphics ability but only if you have the right rigs with, as has already been mentioned, AXIOM (ATi) or MXM (nVidia) expansion slots.
And as I've said before the cost and trouble of finding a graphics board that fits your thermal limits, and then replacing is usually not worth it. Makes more sense to sell your laptop and then buy a newer one with better features you want.
Laptops do keep their value better than desktops and yours is fairly recent, you could think about selling it if you're really looking to do some gaming on it, but otherwise you're hooped.
