Macbook Intermittent shutdown repair – A1706

This time we got a Macbook A1706, experiencing intermittent shutdowns. After Macbook shut down, it would not turn on for a period of time.
Clearly, The customer was in need of some kind of Macbook Intermittent shutdown repair service in Adelaide but was not clear exactly what.
He called us and we have advised him to come around to our Adelaide workshop for a Macbook diagnostic.

The first thing we did was to have a look inside while the customer was waiting and check if there was any visible damage. The macbook looked in a pristine condition apart from regular dust and fluff build up inside.

We did a couple of measurements and spotted the issue being with the logic board. It was not passing secondary line voltages. Those are required for the device to circulate electricity to the secondary components which work on lover than 20V.

We quoted the customer and he left it for us to attempt Macbook Electronic Repair

When we took the board out we start measuring around for a short circuit and investigate for liquid damage. Macbook liquid damage is the second often type of repair we get in our Adelaide Macbook Repair Workshop.

Please note: This is not educational material. It is rather a showcase of the services we offer.
Therefore, it should be used as general guidance on what to expect of such repairs.
In case you have a similar device and need the repair, always rely on professionals. These are sensitive electronic devices, and small mistakes may cause irreversible electronic damage. Which may require whole part replacement for 2 or 3 times the cost.

On a close inspection, we notice some oxidation around the charging chips which may explain why the system was not turning on. However the battery seemed full, so should turn on on battery power at least even if it doesn’t charge.

So we had to look around voltage regulator chips. That was our next course of action for this Macbook not turning on repair

Macbook Intermittent shutdown Repair Process

Under a high-grade microscope we visually “walk through” the logic board inch by inch. This process is aiming to determine oxidated components.

As seen in the video, we located oxidated pin of one of the power regulator chips. This explains why Macbook was experiencing an Intermittent shutdown and would not turn on straight away.

We have a sophisticated equipment workshop with high accuracy microscope, ultrasonic cleaning bath, reflow machine, and tools for micro soldering to achieve high-quality logic boards repairs. With thousands of components in stock, we quickly locate and replace failed components!


With some fine soldering skills, we managed to clean the area and resolder the voltage regulator back ensuring good contact. Now we have all required voltages passing through the system.

The last step is to run extensive tests and leave the Repaired Macbook to stream overnight. These intermittent shutdowns occurred every couple of hours when in use. And the best way to test it would be to loop over a video all night long.

Repaired, not Replaced!

We are committed to reducing e-waste in Australia. How we do it is by educating our customers on the reparability and longevity of their devices, as well as providing affordable Macbook Repairs here in Adelaide.
Although our best intentions and hard work, this is not an easy task. Customers must accept that cost of high-quality electronic repairs, is between a third and half of the price of a new device. However, with the current trend of planned obsolescence in electronic design, we see more and more Macbooks having shorter lifespans. To tackle that, while we do our repairs we target common planned obsolescence engineering design mistakes to ensure we extend the life expectancy of the Macbooks we repair. Check some of our Macbook Repair Cases to get an idea of the process.

That said, if we buy a new one or write it off via insurance, it does not guarantee that the new one will not meet the same fate as the older one pretty soon.
As matter of fact, quite often we see accidents reoccurring within less than 2-year gaps. If we can save 2000$ or even 1000$ today by repairing our faulty Macbook is brilliant. That’s an extra half Macbook cost ready to be spent on another one when the time comes or our need for performance increases.
When that time comes is up to us to buy a new one or keep pushing the one we have, but delaying it by a year or three is always a good starting point and saves another abandoned Macbook from polluting our one and only Planet.
