Question 1

What is a MacBook logic board and what does it do?

Accepted Answer

The logic board is the main circuit board of a MacBook — it holds the processor, memory, power management and every connection between components. If the logic board fails, the MacBook will not start, charge or run correctly, regardless of how healthy the other parts are.

Question 2

How do I know if my MacBook has a logic board fault?

Accepted Answer

Common signs are a MacBook that will not power on, no charging light, random shutdowns, no display despite power, or USB and Thunderbolt ports that have stopped working. A proper diagnostic is the only way to confirm it — many of these symptoms can also come from a battery or charger fault.

Question 3

Can a MacBook logic board be repaired, or does it have to be replaced?

Accepted Answer

In most cases it can be repaired. ZA Support works at component level — replacing the specific failed chip, capacitor or connector under a microscope — rather than swapping the entire board. Component-level repair is usually faster and far less expensive than a full board replacement.

Question 4

How long does a logic board repair take in Johannesburg?

Accepted Answer

A logic board assessment is typically completed within one to two business days. The repair itself depends on the fault — straightforward component repairs are often done within a few days, while complex faults needing parts can take longer. You receive a written quote and timeline before any work begins.

Question 5

Is it worth repairing a MacBook logic board or should I buy a new one?

Accepted Answer

For most MacBooks from the last several years, a component-level repair costs a fraction of a replacement machine and restores the device fully. We give you an honest assessment first — if a repair is not economical for your specific model, we will tell you so before you commit.

Question 6

What causes MacBook logic board failure?

Accepted Answer

The most common causes are liquid contact, power surges or faulty chargers, physical impact, and component wear over time. Liquid damage is the single biggest cause we see in our Hyde Park workshop — and the faster it is treated, the more boards we save.

Question 7

Will I lose my data during a logic board repair?

Accepted Answer

A logic board repair does not erase your storage. On most MacBooks the data lives on the SSD, which is separate from the components being repaired. Where a board fault risks data access, we discuss data recovery options with you before starting. We always recommend a backup where one is possible.

Question 8

Do you repair logic boards on M1, M2 and M3 MacBooks?

Accepted Answer

Yes. ZA Support repairs logic boards across Intel and Apple Silicon MacBooks, including M1, M2 and M3 models. Apple Silicon boards require specialist micro-soldering equipment and experience, which is the core of what our workshop does.

Question 9

What does a logic board assessment involve?

Accepted Answer

We test the board under power, measure voltages across the power rails, inspect for corrosion or damaged components under magnification, and isolate the fault. You then receive a written, fixed-price quote and a clear explanation of what failed before any repair work starts.
