Happy to see the refresh. These APU systems are great.

The alarmingly priced usb-c dock works. Three monitors around laptop, no problem. The LTE modem works out of the box on windows and works with some arguing on Linux (I built a driver from GitHub, but that's probably improved since).

An not-obvious benefit of the Lenovo ones is they're on the approved list for AMD's employees, so broken stuff is pretty immediately apparent to lots of people with internal paths for reporting bugs to Lenovo.

What's the battery life like on linux?
That's gonna depend on the distro and kernel, as different ones have different drivers, different power saving things, different apps. In general all modern distros should have decent support for power saving out of the box, but things like wifi cards typically have crap/buggy drivers when it comes to power saving (but again it depends on the hardware and driver)

That said, the spec sheet MobileMark benchmark says battery life is as good as 14.3 hrs in max battery setting on WUXGA Low Power (non-touch), Win 11, 52.5Wh battery, versus a performance mode getting 5.0 hrs on 2.8K OLED (non-touch), Win 11, 39.3 Wh battery. With 'local video playback' lasting longer. So I guess it's very hardware and use-case specific. (https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_T...)

Eight or ten hours? I don't take a power cable with me for the day. Would probably be better if I worked out how to set any of the power saving things, this is Debian out of the box. That's mostly showing emacs, I expect it would be worse with a browser.
I'm on a Zen3+ APU (Thinkpad Z13) and TLP has worked great for me. TLP has nice out-of-the-box defaults so you don't need to tweak anything if you'd like, but you may need to disable any existing power management systems, if you're using a full-fledged DE, as they could conflict.

Two cool things that TLP does is allow you to set battery charge thresholds for better battery longevity (I limit mine to 80%), the other being automatically changing the energy performance preference (EPP) in the amd-pstate driver, so if you're on battery you could get it to automatically switch to power saving or balanced powersaving etc. I get an 8-10 hr battery life even with the 80% cap capacity, with several MS webapps running in Edge (Wayland), including Teams and Outlook, VS codium and Firefox running in the background.

We’ve got another visitor running Linux on it

I love my Lenovo dock. Still itches my design scratch and is super reliable. Least reliable part is just the USB c cables as usual
I don't think I'd have bought one out of my own money. It was something like $500, rather close to the cost of a standalone computer. But it's now cable tied to the back of a monitor and the single usb cable to the laptop for power and everything else is aesthetically glorious.
hah I got it from work! Lol
