Flaws:
- There is cosmetic degradation
- The laptop is gradually losing hassle-free hardware support from the latest popular Linux distributions. (Trackpoint crashes randomly in Ubuntu; Sleep/power management has never worked properly).
- I had to replace the keyboard after 3 years (the keys mechanically wore out and became loose). I had difficulty finding new replacement keyboards recently (although this is more an indictment of the UK's trade situation).
- The buttons on the main touchpad are slowly failing; Near as I can tell it isn't possible to replace these without replacing the entire "top case". I use an external mouse to slow the decline.
That's disappointing. How well do Debian and Fedora hold up from that POV? Even if support has also regressed there, those are probably the distributions where tracing and reporting that regression would be easiest.
I’m much happier with the t450.
This is not entirelly lenovo's fault though - the latest T-series are eyeing 1 kg and with the laws of physics not having changed, it is impossible to deliver the same sturdiness. My next one is going to be a P-series. Let's hope it still has some quality.
