So I have an x360 m3 that is not turning on. No power led light when plugged into the adapter. I have pulled the laptop apart an checked many places with a multimeter. 19 volts out of the charger, 19 volts at the connector out of the dc jack into the motherboard. I am taking this as the dc jack is ok although it was loose. I have 3.3 volts and 2.8 volts at the pins off the board that connect to the battery (I looked for info about what this reading should be but no luck). I have 3.3 volts at the base of the ribbon cable for the power button where it attached to the motherboard. I have checked the continuity across the power switch and it drops to 0 ohms (or just near it) when pressed. Does this sound like the motherboard is fried if it still won't boot?
