All I can offer is anecdotal evidence. I have had two enterprise issued Lenovo laptops, which are/were rock solid for 11/6 years now. Both times I had to replace the battery were easy to do, with rock solid documentation and demonstration videos.

The Dell on the other hand, corrupted it's UEFI bitlocker key causing complete data loss, BSOD for no reason (and happens to my coworkers too) and overall has a shabbier feeling build quality. It's not even been 2 years and the keys are peeling off. I've not really had to delve into repair documentation, but I don't think it'd beat what Lenovo offered.

But that still beats dealing with HP. HP had the worst reliability and documentation, providing stuff that looked like an 11th generation fax scan. I ended up buying the wrong parts simply because their diagrams were so ambiguous.
