The good news: most devices that won't power on can be repaired quickly and affordably. The better news: we're based just minutes from Bryanston, and we've fixed over 18,000 Apple devices across the Johannesburg metro area. This guide walks you through what causes your device to fail, what to expect when you bring it in, and why ZA Support is your best option for fast, honest repairs in the northern suburbs.
Why Your Apple Device Won't Turn On
Power failure in Apple devices almost never means the device is "dead." It means one of several components has failed or disconnected. The most common culprits are the battery, the charging port, or the logic board—the main circuit board that controls everything.
A dead or degraded battery is the most frequent cause we encounter. Lithium batteries degrade over time, especially if your device is over four years old or has been through heavy use. Load shedding in Johannesburg can also stress batteries when devices cycle through irregular power patterns. If your MacBook, iPad, or iPhone won't respond to a charge, the battery may no longer hold voltage.
The charging port comes second. We see corroded ports regularly—especially on devices used in humid environments or near moisture. A device may sit in the workshop, powered and functioning, once the port is cleaned and tested. If the port is damaged internally, it can prevent charging entirely.
The logic board—the brain of your device—is the more serious scenario. Liquid damage, power surges from unstable electricity supply, or manufacturing defects can damage this component. It requires specialist diagnosis and often board-level repair. This is where experience matters. Our technicians have trained on thousands of logic board repairs and can often recover data and restore function where other repair shops resort to device replacement.
What to Expect When You Bring Your Device to ZA Support
We start with a diagnostic assessment. This costs R599 and takes between 30 and 90 minutes depending on the device type. During diagnosis, our technicians will test the battery voltage, check the charging port for debris and corrosion, and run power tests on the logic board. We'll then show you the results on our testing equipment and explain exactly what's failed.
From there, repair costs depend on the component. A battery replacement on an iPhone typically costs between R1,200 and R1,800. A MacBook battery runs R1,500 to R2,400. Port cleaning or replacement ranges from R599 to R1,200. If the logic board needs attention, we'll provide a quote based on the specific failure. Across all our device repairs, we've developed streamlined procedures that mean most power-on failures are resolved within two to three working days.
Turnaround matters when you rely on your device for work, study, or communication. We prioritise next-day service for battery replacements on smaller devices, and three-day turnaround for more complex repairs. During load shedding periods, we operate on backup power in our Hyde Park workshop, so you can drop off and collect on schedule.
All repairs come with a three-year warranty on parts and labour. This means if a battery fails within 36 months, or if a charging port issue recurs, you're covered—no repeat diagnostic fee.
How We Diagnose Power Failures Accurately
Accurate diagnosis saves money. Many repair shops will replace a battery without testing the logic board, or replace a charging port without checking for underlying electrical faults. We don't work that way. Our diagnostic process uses several tools and tests:
Multimeter testing checks whether the device is receiving power at all. If voltage isn't present at the charging input, we know the port or charging circuit is the problem.
Software testing on logic board test rigs determines whether the processor, memory, and power management chip are responding. A failed power management chip will prevent the entire device from waking, even with a fresh battery.
Microscopic port inspection reveals corrosion, bent pins, or internal damage that the eye can't see. Many devices are repairable once we've cleaned oxidation from charging contacts.
Battery capacity testing shows the exact health percentage of the battery. If a device is four years old and the battery is at 40% capacity, replacement is the sensible choice even if it's not technically "dead."
This thoroughness is why clients from Bryanston, Sandton, and surrounding areas travel to our workshop instead of using local high-street repair shops. We give you facts, not guesses.
Logic Board Repair for Serious Power Issues
If the battery and charging port test fine, but your device still won't turn on, the logic board is likely compromised. This is more serious—but not hopeless.
We specialise in logic board repair. We've recovered devices that other technicians declared unrepairable. This includes replacing failed power management chips, repairing burnt circuit traces, and occasionally replacing the logic board entirely if it cannot be salvaged. For clients with important data on the device, we can often extract information even if the motherboard cannot be restored to full function.
Liquid damage is another common cause of power failure that requires board-level work. If your device has been near water, coffee, or tea, corrosion on the logic board can create electrical shorts that prevent startup. We have recovered over 12,000 liquid-damaged devices by carefully cleaning the board, identifying shorted components, and selectively replacing failed chips. Our guide on liquid damage repair provides more detail on this process.
Cost and Warranty for Power Repairs in Bryanston
Let's be direct about cost. An R599 diagnosis is mandatory and non-negotiable—it ensures we quote accurately and don't waste your time or money on unnecessary repairs. From there:
All repairs carry our three-year warranty on parts and labour. For MacBooks and iPads, we can arrange battery replacement overnight if we have stock—important if you're a professional who can't wait.
We're open Monday to Saturday, 09:00 to 17:00. Our Johannesburg address is in Hyde Park, five minutes' drive from Bryanston along Jan Smuts Avenue. You can book online at zasupport.com/book or WhatsApp us on 064 529 5863 if you have questions before you arrive.

Frequently Asked Questions
Q: Can a device that won't turn on be repaired, or is it ruined?
Most devices that won't power on are absolutely repairable. The most common causes—dead battery, charging port failure, or power management chip damage—are all fixable. Only in rare cases (severe physical damage, water damage beyond recovery, or failed logic board) is a device unrepairable. Our R599 diagnostic tells you which category your device falls into.
Q: How long does a power-on repair take?
Battery replacement typically takes one to three working days. Charging port service takes two to four days. Logic board repair can take up to five working days if we're replacing components or sourcing parts. We'll give you a precise timeline when you collect your device after diagnosis.
Q: Is it safe to keep trying to charge my device if it won't turn on?
If your device is warm when you plug it in, or if you smell burning, stop charging immediately and bring it to us. Continued charging on a failed logic board can cause fire risk. For cold devices, one or two charge attempts are safe, but beyond that, bring it in for diagnosis.
Q: Will you recover my data if the logic board is damaged?
Often yes. Even if the logic board cannot be repaired and the device won't function, we can frequently extract data from the storage chip. This is more expensive than standard repair (R1,500–R3,000 depending on the device), but clients with critical photos, documents, or work files consider it worthwhile. Ask about data recovery during your consultation.
Q: What's the difference between ZA Support and high-street repair shops in Johannesburg?
We employ Apple-trained technicians, use genuine parts, offer a three-year warranty, and specialise in complex repairs like logic board work. Many high-street shops replace entire devices rather than repair components, and offer shorter warranties. We focus on fixing your device affordably and keeping it in use.
Q: Can load shedding damage my device and cause it not to turn on?
Indirectly. Rapid power cycling during load shedding can stress batteries and power management circuits. Unstable mains power can also damage charging circuits. If your device failed to turn on during or shortly after load shedding, the power supply or charging circuit may be compromised. Bring it in for testing.
