Just leaving this here in case you don't know: there are also the Framework laptops, which are designed to be modular, upgradable, and have easy to buy replacement parts.
They even sell motherboards, so you can now get a e.g. Intel Core Ultra motherboard for your 3-4 year old laptop.
Of course It's a bit more expensive than a used 10 year old Thinkpad, but it kind of competes with other high end laptops, and it is cheaper especially when you consider it's designed to last more
(Not a sponsored post, just glad there is a company that makes such products, and that when I broke a part I could just go to their store and order a replacement instead of searching for serial numbers on random online stores etc like I've done before)
Tasker: I haven't used it, but I've seen useful automations over the years from people online and I would probably use a good FOSS alternative.
