Why doesn't SMC reset on a 2012 Macbook Air?

Question

macbook

SMC is not reset on Macbook Air 2012, I don’t understand the reason, I seem to press everything like Apple says on the site, but anyway, in theory, the settings in “Energy Saving” should be reset, but this does not happen.

Answer 1

try an external usb keyboard.
if the laptop after pressing the combination sings "ta-da" at full volume after reboot, then the reset was successful, the energy-saving settings may not be reset due to the plugin / lack of rights, etc.
