Doesn't sound like it, not if you have a 943 chipset.
Let me be even blunter then they have been with you. The IGP is built into the northbridge of your laptop. THERE ISN'T ANYTHING YOU CAN DO ABOUT THIS. I have no idea why you're looking for it, but even if you found it you can't do anything to it. If you can't even find it, you lack the skills needed to do anything to it.
Try telling us what the problem is. Perhaps there is another way to help you fix whatever is wrong. Ripping the laptop apart probably isn't the answer.
