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.
