Macbook Air Charging Repair

Straight forward repair we had was this Macbook Air 2017 model which was not charging due to water damage on the DC-IN board.

Apparently the customer spilled some water on the table which seemed like initially haven’t reached the Macbook which was sitting on the table.

But after a week, it suddenly stopped charging. And she called us for an advice.

When it came the Macbook was not even turning on. But customer assured us that it was working fine until it drained the battery and because it was not charging customer could not charge it.

When we connected it to our power supply we could see that PPG3_HOT was not engaging the online circuit and refusing to let charger release power. This is usually when the logic board goes into a protection mode and tries to limit the power to prevent any more short circuits and potential damage.

We start poking around the DC-IN board and measured a couple of hot spots. Immediately we have noticed under the microscope what was causing the short circuit. There was oxidation (Blue-Green sport on the component) on one of the coils, causing the power rail to short.
