My long time fav are Thinkpads.
I'm one of the proverbial Road Warriors (Field service engineer) and can attest that they work for decades despite constant heavy and not often kind usage. I still have a couple from 1993-1997 when they were still under the IBM brand - but actually made for IBM by Lenovo - aside from being slow (1 is 486M, another is Pentium-M cpu) and the backlights getting dim, they still work perfectly. All ThinkPads are highly dust and water resistant with built-in gutters to drain away spills out the bottom. Never had any issues with hinges going bad nor cracked cases both of which are something very common with other makes.

Very nice thing is that Thinkpads can be easily repaired if ever needed. Lenovo carried on the IBM traditions of assembling them with screws vs 'snap & crack' housing latches, providing actual repair manuals and of course parts lists. Currently using a ThinkPad P15 workstation w/gen 10 i7, 16gb memory & NVIDIA® Quadro RTX graphics. That replaced my T410 circa 2010 which still works perfectly, is just slow because of the i3 CPU and only 4gb of memory.

FYI: When IBM exited the small PC market starting in 2004 there was a massive outcry from users regarding the fate of the near-bulletproof ThinkPads. Lenovo paid attention to that and on May 1, 2005 paid IBM a very tidy sum of money to buy all rights to the ThinkPad brand name along with all other IBM PC's and continue production of this top-end gear. Ja ThinkPads are pricey but well worth it.

As for the other Lenovo laptops - meh. Still very well built for being 'Consumer grade' but they ain't ThinkPads...
