I must have been lucky as I never really had a problem with my fairly early example of a Z16, except for about 1 week into ownership when the SSD corrupted itself. After a precautionary SSD swap and a rebuild it has been fine ever since.
Generally speaking, I love it - even if they have swapped the Fn & Ctrl buttons to be the wrong way round, unlike any other ThinkPad! Hopefully the Gen 2 will support PD3.1 compliant power supplies rather than the 20V 6.75A proprietary one.

Took them just long enough for me to return my unit for them to fix the problem. Looks like I'm getting a new unit. :P

I installed the new BIOS, i don't see any reboot, but now the fans are never running, and the CPU is getting very hot and throttle a lot.
back to previous BIOS

AMD and instability, like bread & butter. Glad I went Tiger Lake earlier this year.

And no, I'm not blaming AMD for this one. I know it's probably not their fault, but it sure would help if they involved themselves more in laptop development, like Intel does. There's a lot of money to be made there.

Here's hoping the next iteration gets zero flaws at launch.
