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.

@Bagas any update about this issue?

Could you try if this patches help (and report back to the list)

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?

Can you reproduce this in 6.8.7?

dmesg

Hello
for me the same problem with recent Ubuntu 24.04.1
Kernel 6.8
I tried also Zabbly kernel - no help (6.10.11-zabbly+)

dmesg attached

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 :-|

                },
        },


how to compile the kernel for ubuntu when someone interested e.g. there

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

Hello,

I am having the same issue: Asus ExpertBook B1502CV

Keyboard not working for any Debian-based OS (Ubuntu, Lubuntu, Kubuntu, Kali, Debian). But working with Fedora, Windows etc.

Could you help in resolving?

Thank you.

Hi Nirmal
I can only suggest you to do the same as I did - open the link 'how-to-compile-linux-kernel...', but before compiling it, add this section to the file drivers/acpi/resource.c. For me it was the solution
btw maybe in advance check if 'B1502CV' is compete boardname - with dmidecode utility

                        DMI_MATCH(DMI_BOARD_NAME, "B1502CV"),
                },
        },

All B1502CV models should be covered by the kernel after this commit:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/acpi/resource.c?id=158d0f3700fd7190df609a0a61294f29ae698d9e

Which is available in recent kernels like Fedora is using and should have been backported to stable kernel series like those used by Debian. Please contact your distribution's kernel maintainer asking them to backport all the recent changes to drivers/acpi/resource.c:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/acpi/resource.c?id=158d0f3700fd7190df609a0a61294f29ae698d9e

Note AFAIK most have already been picked up by Greg in the various stable kernel series.
