Macbook Air is a very popular model, which we do receive on a regular basis. Mainly with not turning on issues caused by either liquid damage or other power-related problems.

We took the Macbook apart and start investigating the issue preventing it from turning on.

On initial inspection, we have spotted multiple corrosion spots on both sides of the board. But heavier one was around the power rails.

One particular part was badly corroded and even managed to corrode and strip the protective coating of the board. You can see how shiny copper become visible and even some part of it disappeared due to corrosion and constant current flow.

We start working on the heaviest damaged area first to isolate the short and check if any traces were destroyed. The blue/green corrosion visible on the bottom capacitor is not visible on the previous picture. This is due to this Macbook been worked on by another repair shop before us.

They seemed to brush the oxidation off with spirit and toothbrush. But that, unfortunately, is not always enough to get rid of all corrosion on the board.

Once we start soldering and replacing the components the corrosion spots hiding underneath showed themselves.

This is how we ensure that our Macbook liquid damage repairs are long-lasting and reliable.

However, this was only half of the battle. One of the voltage regulator chips was not working as expected too. Due to the traces being completely destroyed by the oxidation.

Next step was to replace this chip and re-wire them missing traces.

Once short removed and chip replaced, laptop turned on and fan kicked in.

Once we replaced all bad components, repaired traces and ensured macbook now accepts power. There were one last step – to dip our logic board in the ultrasonic cleaner. This way we can ensure there is no more liquid residue which may damage other components in the long term.
