13 Macbook Pro 2018 repair – won’t charge

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

Customer used it until the battery drained and subsequentially 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 completion of the diagnostic, we have provided clear pricing to the customer and waited to 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.

The Cause

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 turn-on of this Macbook?

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

In this case, we have a faulty charging chip which gets power direct 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 clearly see on the picture that there must have been a 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.

Repair Process

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

First thing we have measured was the internal resistance of the charging chips. Voila, we spotted immediately deviation from expected values for this charging chip right here.

The Result

With replaced charging chip, now we have fully functioning and responsive Macbook Pro. This 2,500$ laptop was saved for ending in the bin yard or being parked on a drawer until next spring cleanup. We saved the owner thousands, by not having the logic board replaced as quoted by other repair shops. Even falling in Apple’s sales pitch and buying a new one.
