Am I missing something, or can an entire replacement keyboard not be had for ~32 EUR? https://www.amazon.com/Replacement-Keyboard-Lenovo-Thinkpad-...
Also… I have a T460p, bought in 2016. Perhaps I've gotten lucky, but it's well out of warranty at this point and we've only cracked the S key. (But the key functions, so I've not bothered to replace it.) The TrackPoint™ nub needs replacing, though, the original power supply failed and was replaced, and my battery is pretty close to dead after ~4.5 years (I think I get ~an hour of life?)
