A1708 2017 Macbook Pro Not Turning On causes

This week we had a 13″ Macbook Pro in our Adelaide Workshop. Unfortunately, it was not turning on and responding to the power button press.

Our not-so-fancy charger shows only 5V and no current consumption, immediately pointing us towards an electronic fault.

New generation USBc model Macbooks communicate with the charger all the time and if something is not going well within the Macbook they do not let the charger to output 20V. Instead, they limit the voltage to 5V to prevent any future damage or fire hazard.

Macbook Pro Not Turning on – the Repair process

We could immediately spot the abundance of dust on the bottom side of the logic board. Quite often this layer of dust traps organic materials like hair and breadcrumbs creating ideal ground to absorb humidity from the air.

There is one solution for such failure, and it is a Macbook Not Turning on Repair in Adelaide.

Looking closely around the charging chips, we could spot oxidation towards the right side of the right CD3215 IC. Small oxidation like this one is most likely caused by breadcrumbs floating within the Macbook and an unlucky one getting stuck in the dust.

Unfortunately, organic materials have oil and other corrosive agents within them. When in contact with air, heat and electricity starts a chemical reaction known as oxidation. Once started, oxidation similar to rust, “eats” through the traces and interrupts signals required for those chips to work seamlessly.

Once the repair is complete, we can assemble the Macbook and run a full suite of diagnostics to ensure a reliable and timely repair in our Adelaide Macbook Repair workshop.

Once assembled we could see that the charger now is communicating with the charging chips and is happy to provide 20V, together with 2.7A to charge the battery.

We have completed this repair in a span of a day, Another Macbook is saved from ending up in the landfill!
