Hi Guys,
Today I received a Macbook Air 13" which is not coming on. I checked the power rails and found out that the PPBUS_G3H is showing .OL on the multimeter. Now here is what I did. I measured every component where PPBUS_G3H should be present, and it measured as .OL. I understand that .OL means short to ground. Am I correct in saying that ? How do I troubleshoot it further and make the computer work. Please advice. Raj.
