The buttons and switches on all Framework 13 systems are in the same location.
This is to make it compatible with our chassis and the Coolermaster standalone case or your own 3D-printed case.
Of course the normal laptop chassis doesn’t use the mainboard power button, only the coolermaster case does.
The button (SW1) in your picture is the power button. It acts the same way as the fingerprint reader power button above the keyboard.
What support is telling you to do, is to press down on the chassis intrusion switch, which is between CPU cooler and RAM slots, at the top.
See my picture below with SW3
