I don't know about you, but every laptop I've had suffered some sort of malfunction sooner or later and I never bothered to have them serviced because it was too much of a hassle - especially seeing how a friend of mine outright battled Lenovo support over mundane things like a failing keyboard despite everything being still in warranty.
Specific issues by laptop:
1. Pressure marks on screen, failing USB ports, cracked hinge after three years.
2. Pressure marks on screen, failed battery, failing power supply socket after seven years.
3. Warped reflective layer in screen, rattling fans, overheating despite fan replacement (which I did at home and it took three hours) after five years.
I also broke the butterfly keyboard on a 2019 MBP I was using at work.
With the Framework I can address each and every one of the mentioned problems myself - just need to order parts and spend half an hour or so per item.
Guess my normal usage is more destructive than your trips. The main driver of wear in my case was always commuting with the device and thus also plugging/unplugging things several times a day.
Also if you hold a 2kg closed laptop with one hand - you're going to have pressure marks and I learned that the hard way.
Anyway, all around me people have always had hardware issues - also with Apple products. I recall replacing the battery in a late 2011 MBP because it was swollen as it failed from age alone.
Bottom line is that I believe you, I just think you're an outlier.
Similar here. When I trade in my old MacBooks after 4-6 years of use they function like new and look almost new, and I do plenty of moderate-heavy dev work and traveling.
I have a nearly 5 year old ThinkPad that's in great condition too. Never needed a repair, though it's had a couple of spells where it acted funky that resolved themselves.
In Australia, all of these things would be returned for a full refund under Australia Consumer Law as a major fault, there is no time limit, just expectations of a reasonable consumer.
Would really have to come down what a reasonable consumer would expect; that is part subjective and part objective. If you could show an experience of having laptops for various lifetimes, some extending beyond 7 years some below, none having a failing power socket, that might be sufficient to convince that it is a major fault. If it is a cheap laptop maybe you don't have a chance, but a premium product you could argue that it failed to be durable.
(I read this as the power socket in the laptop, not so much the power supply, obviously you'll have less luck there.)
