PS5, Line 48: battery_status
> this is not a good test. […]

the battery_status is only reading if the returned value from the host command is 0 see https://review.coreboot.org/c/coreboot/+/78321 I'm not sure this is the right way to go about this because that would only matter if the battery is cutoff (physically or by ec command both cause the host command to return 0)
