OpenBSD on laptops

Lenovo ThinkPad Laptops

Lenovo ThinkPad laptops are well supported. I used them from time, when there was IBM logo on them and I was IBM Business Partner. I bought my last one on 24.03.2023. It was Lenovo ThinkPad E14 Gen4. It was the one I used during my OpenAlt 2023 presentation. The charging of machine stooped working properly and started to be ineffective. I had to manually switch hw.perfpolicy=low, otherwise the machine under high load gradually decreased battery till machine power off. I reported the issue on 27.06.2024 and I returned it later. I remember, that I had IBM Lenovo R30 with removable battery. When the battery died, I removed it and the machine was usable as "server" for few next years. Anyway, I switched back to older ThinkPad. Then there died RTC and the ntpd was unable to compensate and handle time synchronisation. The even older ThinkPad had issue with keyboard space key. No problem for server mode, but not good for machine to take around with me.

I have been already for some time considering TUXEDO computers. I decided, that now is the time to try them.

TUXEDO Laptops

I bought my first notebook from TUXEDO Computers on 18.04.2025. It arrived from Germany on 05.05.2025. I installed OpenBSD 7.7 to the machine, migrated data there and it become my primary machine on 08.05.2025. The specification and status of OpenBSD support is recorded in my article TUXEDO Aura 14 Gen3
