Battery life was terrible compared to a Mac (6 hours if I was lucky, barely 4 hours when in video meetings). S3 Suspend worked badly, the battery would drain very quickly. Devices would often not come back after wake (particularly the trackpad). During video meetings, the fans would go into full blast (though they were more quiet than most non-M1 laptops). Noise cancellation was quite bad on Linux (ok-ish in Windows). Lenovo’s own USB-C dock wouldn’t work with 4k@60Hz (works with Windows, Linux misconfigures the lanes and didn’t use HBR3).
It was one of the models that was certified for Linux (IIRC even Fedora). But the whole experience was miserable. I bought an M1 MacBook and didn’t look back.
