That's it precisely. For a cold-boot or return from hibernation the PC
goes through the BIOS power-on self test and configures the devices.

When doing suspend/resume all device state has to be saved by drivers
and restored on resume.

If acerhk implemented the RFKILL API the power-management system would
ensure that the state of the 'switch' was restored during resume.
