Sure the parts I needed weren’t available. Which is probably the problem with these iFixit scores. They should really wait for the laptop to be a few years old and then look and see if the stuff that’s actually breaking on the laptop are actually repairable with the parts available.
For this particular laptop even though it had a really good iFixit score, I couldn’t even buy a new touchpoint nub (or whatever HP calls it). The old one completely disintegrated but the nub was different than other HP laptops, so the ones I tried to buy (even for other elitebooks) wouldn’t fit. The nub the laptop needed simply wasn’t available anywhere.
No, LGPL just allows linking to differently-licensed software.
Basically linking copies some code from the library into the program that uses it, making any linked software a derivative work.
Sellers of proprietary software libraries give permission for this specific type of linking in their license. LGPL gives the same permission to people who are otherwise following the GPL. LGPL used to be called the “library-GPL” because it is the GPL plus permission to use the library linking mechanism.
