I knew nothing about computing about half a decade ago, but recently have bought a lot of cheap old laptops on Ebay and from junk shops, and have learned a fair bit from tinkering with them. Can now do basic things like installing and removing various types of hard drives, memory modules, CMOS batteries, etc, and also know a reasonable amount about Windows and Linux operating systems. Have never got round to learning any programming languages, but did master a fair bit of BBC BASIC about thirty years ago, though that's irrelevant now.
One impression I have about modern laptops is that they're far harder to work on, as it's difficult or impossible to access many of the important components. I even briefly owned an Asus laptop where the battery was sealed in, and to change it one would presumably have to take the machine to an authorized workshop or even return it to the factory, no doubt at great expense.
