I had a dell XPS laptop for work a long time ago, and it was one of those desktop replacement models with a desktop GPU. I was extremely unlucky and it happened to have a doomed GPU model - bumpgate, I think - so it would typically fail after a few months.

Dell came to my workplace during work hours, on a day's notice, 6 different times, to replace the GPU for free because it was under warranty.

I've had some bad experiences with Dell in the years since (their monitors have absolutely horrible firmware now so I can't recommend buying them anymore) but their warranty service was great then and is still pretty great now. Cross-ship RMA for things like monitors is a great perk.
