Linux

There are a bunch of probes in the linux hardware database. You can check what they are like for your exact model.

Mint is lovely, as are all other Linux distros. However, if you want the latest stuff without going off piste and compiling it yourself, then a rolling, bleeding edge distro might appeal to you. You do mention that you have prior Linux experience.

I own a UK based IT company (as you do) with two other partners (I'm MD and not a doctor) and a slack handful of (lovely - obvs) employees. I personally like Arch on my gear. I used to sport Gentoo but my nadgers complained about being overheated too often. I still have a fair few Gentoo VMs lying around the place.

You might like to try a https://manjaro.org/ effort - I prefer the Plasma desktop spin (KDE). That's Arch with a few more GUIs. Their Konsole is quite something with zsh and a very stylish prompt.

So far I have managed to get Linux to work on everything I have access to which is rather a lot of hardware. Back in the day wifi was a bit wanky and there was ndiswrapper but nowadays I generally find that laptops from HPE and Dell are just as well supported with Linux as Windows, often better.

I finally ditched Windows on my stuff at Windows 7 - that was my wife's laptop - a GPU update screwed up and that was the final straw. She has been an Arch user for a good seven years and could not give a shit about what is running on her laptop, provided it works and does stuff.
