> having to replace an entire Chromebook keyboard because a single key doesn't work. Stopped reading there. I'm typing on a Lenovo Thinkpad L430; it has a couple of defective keys - they're arrow keys, the keys I use most often, because I like to scroll using the keyboard. I bought replaccement keys online, and had to buy them from Poland (Lenovo don't sell them). You have to go through a rigmarole to select your model, and then you have to select the key you want, and then eyeball the key and compare it to closeups on the order form. Two weeks later they arrived; they look OK, but they don't fit. They're too big. You can't tell just by looking, but they're a fraction of a millimetre bigger than the hole they're supposed to fit in. I gave up, and replaced the Thinkpad (a replacement keyboard would have cost as much as the Dell Inspiron I bought second-hand).
