New thinkpads are trash unfortunately. Lenovo really cheaped out on their build quality. I’ve had to fix multiple lenovo laptops and one of their all-in-ones and the corners they cut made the repairs either impossible or extremely difficult.
One new ideapad had to go back to them twice with motherboard issues.
Replacing the keyboard is impossible, you need to replace the whole front panel of the case becuase the keyboard is plastic rivited in place.
The all-in-one started as a simple ram and storage upgrade, but in order to do that the whole back panel needs to come off. Its snapped on but the LCD panel itself doesn’t have any subframe around it, so when opening the back panel theres a very high chance of you cracking the display.
I’ll second tumbleweed. I use it on 4 separate devices and its rarely given me any issues. If it does, it has built-in recovery snapshots - it takes 30 seconds to roll back a bad update.
