either using the input cover power button. or using the sw1 switch on the board, ( and the lid closed switch, to see the LEDs) the behavior appears to be the same.
this is the behavior i observe:
with battery connected, and power disconnected.
nothing. no response to button.
with battery connected, and power connected.
LED is orange. (looks like red + yellow on board. actually low green )
push button: LED turns off. flashes Red, then comes on Red and switches to orange.
Ocassionally (1 out of every 5 to 10 tries ) the flash of red is a a flash of red to orange.
Ocassionally it’s white for a moment.
with battery disconnected, and power connected.
LED is white. (looks like blue + green, actually all rgb )
push button: LED turns off. flashes white, then comes on white
