Hi everynoe,

Component: Asus Expertbook B2502CVA
OS: Ubuntu 22.04.2 LTS

I am having a keyboard issue after installing Ubuntu 22.04 LTS on my Asus ExpertBook B2502CVA, I discovered that the built-in keyboard is not functioning. The keyboard works perfectly under Windows 11, which leads me to reasonably suspect a hardware compatibility issue with Linux. 

I found that BUG 216158, Bug 216864, Bug 217323 has similarities to my situation, attachment is my dmesg.

Can you try latest mainline (currently v6.5-rc4)? You also need to attach
external USB keyboard to your laptop while building the kernel.

I have tried using the 6.5.0-060500rc4-generic kernel today, but unfortunately, the built-in keyboard still not working.

Hi Thorsten, thank you for your response. I don't quite understand how to manually apply the patches mentioned in the link you provided, and I'm concerned about destroying my current development environment. Do you have any recommended kernel version that would allow me to upgrade and test using the mainline kernel?
Comment 9 Artem S. Tashkinov 2024-04-18 15:27:56 UTC
Can you reproduce this in 6.8.7?

UPDATE: helpfull link: https://bugzilla.kernel.org/show_bug.cgi?id=216158

adding this section to file drivers/acpi/resource.c helped; if someone could do an official patch it would be great :-|

        {
                /* Asus ExpertBook B2502CVA */
                .matches = {
                        DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."),
                        DMI_MATCH(DMI_BOARD_NAME, "B2502CVA"),
                },
        },

Thank you for reporting this. I have submitted a patch adding the DMI quirk for this upstream:
