Please remember that this is the same Lenovo that had issues with installing spyware to muzzle change from their own customers.
I was 10+ years Thinkpad user, bought T480s (over 2.5k euros) that had failing keyboard. I sent it back, and after 6 weeks got the same keyboard, only the key 9 is now collapsed, and as a bonus I can not enter BIOS anymore: computer just happily reboots now.
I believe that this will be studied in schools as a lesson on good brands being destroyed for short term profits.
The lack of swapping and replacing is also an economical dread because people feel bad whenever a thing fails.
Before that, my Lenovo X230t tablet went through three motherboards before finally stabilizing (bad clock, then bad displayport, then total failure) so yeah, I try to stick with what I have as long as possible, and buy at least one year of warranty to fix the near inevitable defects...
