Updating to bios version 1.14, issue persists. This bug is similar to bug 204251. I receive the following (or similar) ACPI errors when pressing any of the following Fn keys: function lock, microphone mute, scroll lock, wifi toggle, sleep, or brightness controls. kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.PEG0.NHDA], AE_NOT_FOUND (20200925/psargs-330) kernel: ACPI Error: Aborting method \NEVT due to previous error (AE_NOT_FOUND) (20200925/psparse-529) This issue is present in dell bios version: Getting SMBIOS data from sysfs.

If yes, does the same problem still exist in BIOS 1.5.2? Plug, why is this not a BIOS regression? It is possible to downgrade the bios, however, I do not trust the downgrade process not to turn my laptop into a paperweight, so I'd rather not attempt that. I'm 100% positive the bios upgrade is the culprit. The Fn keys all worked before the upgrade, and immediately afterward, they stopped working. The bios version was the only thing that changed. I also checked with evtest, and the above listed keys produce no output whatsoever when pushed, with the exception of the wifi toggle key, which does produce an event, but it doesn't actually disable the wifi card. All the function keys work fine in windows. the function keys work fine in Windows even with latest BIOS? so it is Linux that works with old BIOS only? That is correct. Windows function keys work with latest BIOS. In Linux they only work with version 1.5.2. Sorry for the delay, reply went to my spam folder. Any updates on this? Well, no. I will try to raise this to Dell BIOS people. Before that, I don't think we can do anything in kernel before we know what is changed in BIOS. Sorry that I can not get contact with Dell BIOS people. Thus we have no idea what firmware change brings this difference. I'd like to get this closed as there is nothing we can do from kernel' perspective of view. what do you think? I will try reaching out to Dell to see if I can get the information.

Dell's support is worse than useless. Can anyone who has reproduced this comment on whether this happened to be a single or dual boot system? It's dual boot. Bug closed as this seems to be a firmware regression. |
