Back in 2008, I had an XPS M1330 with an Nvidia 8400M GS. Now, if you guys remember this, it was the infamous integrated GPU which it would fail after some heat/cool cycle because the BGA would crack or some such rubbish. I was covered under warranty when I first bought it, but as soon as I exited the period, they clammed up. It was comical - the thing came with a built-in expiry date! Eventually, of course, they caved and extended the warranty on the motherboard to 1 year longer for everyone who bought that. But before that, man, they denied everything.
