It seems that Thunderbolt no longer works on my laptop. That is... annoying. Because it is not that old.
Fortunately, my old "hot spare" laptop still works, so I can get on with my work.
But it looks like I am in the market for a new laptop. I'm not sure that I'd go for a ThinkPad again, which is also annoying because that has been my go-to for a while.
@neil haven't read the whole thread but I've literally just bought the only X1 Carbon I could find on eBay that didn't disclose that the USB-C ports were dodgy.
Only to find that the ports were indeed still dodgy, and that this is a pretty common problem. I just spent £145 on having them resoldered, which I probably shouldn't have bothered doing but the repair shop called me while I was very distracted and I just went "yeah that's fine" without really thinking it through.
