Like the ASUS ExpertBook B2502CBA and various ASUS Vivobook laptops, the ASUS ExpertBook B1502CBA has an ACPI DSDT table that describes IRQ 1 as ActiveLow while the kernel overrides it to Edge_High. $ sudo dmesg | grep DMI DMI: ASUSTeK COMPUTER INC. ASUS EXPERTBOOK B1502CBA_B1502CBA/B1502CBA, BIOS B1502CBA.300 01/18/2023 $ 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.
