Re: Lenovo Yoga 2 Pro Lenovo nm-a074 schematic and boardview
Hi, I could able to find the resistor of 150 ohm. I was deceived by the test points near the connector. The PIN1 start from the left side. I am assuming that the keypad matrix, 3V supplied and PIN1 (CAP_LED_N) is the ground for the backlit LED which is controlled by CPU GPIO.
