Like the ASUS ExpertBook B1502CBA and various ASUS laptops, the
ASUS ExpertBook B1502CGA has an ACPI DSDT table that describes IRQ 1 as
ActiveLow while the kernel overrides it to Edge_High.
$ sudo dmesg | grep DMI
[ 0.000000] DMI: ASUSTeK COMPUTER INC. ASUS EXPERTBOOK B1502CGA_B1502CGA/B1502CGA, BIOS B1502CGA.303 06/05/2023
$ grep -A 40 PS2K dsdt.dsl | grep IRQ -A 1
IRQ (Level, ActiveLow, Exclusive, )
{1}
This prevents the keyboard from working. To fix this issue, add this laptop
to the skip_override_table so that the kernel does not override IRQ 1.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
