There is no scancode per "/lib/udev/keymap". The problem is quite annoying because if the laptop is accidentally sent to sleep or hibernate mode, there is no return back from sleep/hibernate. Pressing the power button has no effect. The laptop can be turned off by long-pressing the power button, with the collateral loss of all unsaved data. WORKAROUND: Remove non-default kernel parameters (ex. acpi=noirq). WORKAROUND: Boot in UEFI mode.
