L860 FCC unlock operation
What does "The L860 model should be usable since 5.14, but it may also require a different FCC unlock operation." exactly mean? Information on how to find out if the device has this model and how to check if there is a problem with the FCC unlock operation would be helpfull.
I've added some additional info on the FCC unlock operation, let me know what you think.
Seems clear to me now, thank you for the clarification.
Wifi rx rates will not reliably get above 25 Mbps on a 802.11n network. This holds for Ubuntu as well. The phenomenon is somewhat chaotic as sometimes I could also get ~50 Mbps, but not in a stable fashion. It also depends on whether the system was booted cold or resumed from sleep. All this despite tx and rx rates given by
iw dev wlp0s20f3 link
I'm unable to verify these claims. As far as I can tell the WiFi is fully working as intended at rates (much) higher than ~50 Mpbs. I may remove these comments after further testing. --PHLAK (talk) 21:14, 10 November 2021 (UTC)
Did you make sure you connected with a 2.4 GHz 802.11n network (no 5GHz, no g, ac etc.)? With a 820.11ac connection I get up to 700 Mbps. But with an 820.11n access point the same network is significantly slower on my Gen9 than on my X1 Carbon Gen4 (25 vs. 75 Mbps), both tested with archlinux.

Slight delay for for Power key
I've constated a slight delay when I try to use the power key / fingerprint reader for shutting down the laptop. If I just press and release, nothing happens, I need to hold it down like 0,2 second for it to work. Logind apparently see this (0.2 press) like `Power key pressed short.` and nothing at all with immediate press and release. Does anyone know if there is anything which can be done to fix that ? I've read a post describing the same issue on windows which makes me thinks this might be in the firmware or lower :< VannTen (talk) 19:48, 11 July 2022 (UTC)
