PS1, Line 10: are disabled once ACPI is
            : enabled
Just for my knowledge, what component writes to ACPI SMI command port and triggers this ACPI Enable SMI?

PS1, Line 48: chromeec_smi_process_events();
Does this end up handling the LID_CLOSED event as an SMI event when OS is expected to handle it.
