13 Macbook Pro 2018 repair – won’t charge

This week we have received a 13″ Macbook Pro 2018 model which won’t charge the battery.

The customer used it until the battery drained and subsequently it did not turn on after that.

These models have 2 USB-C charging chips, which, if not in sync with each other, disable charge on both of the USB-C ports. Most people think if one port is not working, they can keep using the other port to charge the Macbook. Unfortunately, that is not the vase with new generation Macbooks.

After completing the diagnostic, we have provided clear pricing to the customer and waited for his response.

The repair cost for this 13″ Macbook Pro 2018 model is much lower than a replacement cost of the Macbook itself or the Logic Board part.

Cause – Macbook Pro 2018 repair – won’t charge

The next step would be to take the Macbook apart and investigate what is happening with the charging chip. And what is causing it to fail to charge or even prevent the turn-on of this Macbook?

By now, we all must be thinking, what has caused it. And answer to that is so tightly connected to the damage.

In this case, we have a faulty charging chip that gets power directly from the charging ports. That said, we need to investigate the ports.

As expected, we found the reason for this failure at the charging ports. We can see in the picture that there must have been water or liquid damage on the charging ports. This either was a wet charging cable or wet hands while carrying the Macbook.

Therefore, the cause for the damage was a liquid altogether on the charging ports. This shows one more time how sensitive these new laptops are to external factors.

Above, we have explained what may have caused the issue in the first place, which resulted in our quote for the repair.

The first thing we have measured is the internal resistance of the charging chips. Voila, we spotted an immediate deviation from expected values for this charging chip right here.
