      measure +LED_VCC_INV on a healthy laptop when power is provided by battery only.

        On some other Asus models, the faulty component is a coil on LCD panel board. So either changing that or LCD panel should fix this issue.

          thanks,
          you reminded me of a similar problem a few years ago.
          I had solved it by changing the coil.
