I've been doing some research into this. Reviewing "laptop hinge repair" for different brands/models of laptops on YouTube. Even the laptops that
look like they have a single long hinge in the middle do not. They all appear to be two hinges, one on each side. I could not find any brand of laptop that has a single hinge. I'm not saying they don't exist somewhere, I just did not run into any during my searches.
Some hinge designs may indeed be better than others, but based on what I could find, it's not because they have a single hinge - even though outward appearances might make someone think that this is the case. I was looking for other alternatives to the Lenovo because those obviously have two hinges where things like HP's EliteBooks seemed to have a single hinge. So instead of looking for a single hinge design (those don't appear to exist or at least are not common), I am now looking for a solid build (even though heavier). e.g., a Lenovo T480 rather than a T480s, a T490, or the X series. I want solid construction over thin and lightweight. HP's Elitebooks look good too. I have not done my research on the Dells yet, other than YouTube videos on hinge problems, ... but I'll do that research soon. I'm looking for a business class tank basically. Performance isn't so much a big deal. I'll be nuking Windows and installing Linux, and that right there will give a humongous boost in performance over something running Windows.
e.g., Below is an HP EliteBook that
looks like it has a single hinge in the middle. But it does not. There is actually a hinge on either end that has attachment points offset to either side of the hinge so the two attachment points are side-by-side and not straight up and down. Are two offset hinges better than two straight hinges? I don't know. But it's not a single hinge in any case.
