Hi

Similar to issue https://bugzilla.kernel.org/show_bug.cgi?id=216864.

This is a new model for ASUS and the keyboard is not working on Linux. It works in  Windows, BIOS and pre-boot like selecting the kernel version to boot.

Already tried several kernels, inclusive v6.5.1 on Ubuntu 22.04. Also tried Ubuntu 23.10 and the result is the same. Only works external usb keyboard.

thanks

It looks like it's detected but I've no clue why it doesn't work:

input: ASUE1411:00 04F3:31F0 Keyboard as /devices/pci0000:00/0000:00:19.0/i2c_designware.0/i2c-1/i2c-ASUE1411:00/0018:04F3:31F0.0001/input/input15

This could be related, check bug 217660

Hi

I Added to drivers/acpi/resource.c:

static const struct dmi_system_id asus_laptop[] = {
.......
        {
                .ident = "Asus Expertbook B1402CBA",
                .matches = {
                        DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."),
                        DMI_MATCH(DMI_BOARD_NAME, "B1402CBA"),
                },
        },
......

and compiled a custom kernel, and now my internal keyboard working fine. 

Is it possible to add this model to future kernels?
