At ZA Support in Hyde Park, we've diagnosed and repaired over 18,000 Apple devices with power issues since opening our workshop. The majority of Sandton clients who walk through our door with a "won't turn on" device leave with a working computer and a repair bill far lower than they expected. Here's what you need to know about diagnosing the problem, what it costs, and how our team handles it.
Why Your Apple Device Won't Power On
Power failure isn't a single fault. It's a symptom with multiple causes, and pinpointing the real problem requires methodical testing rather than guesswork.
The most common culprits we see are battery depletion, faulty power adapters, and software hangs rather than hardware failure. Many clients assume they need a new logic board when, in reality, a depleted battery or a burnt-out USB-C port is the issue. Load shedding across Johannesburg has also increased the number of surge-related failures—unprotected devices connected to unstable power lines suffer capacitor damage that can disable the entire power delivery chain.
Less common but still routine for us are liquid damage affecting the power circuit, failed solid-state drives that prevent the bootloader from running, and firmware corruption after interrupted updates. Each diagnosis takes a different approach, and each requires different parts or procedures to fix properly.
Our Assessment Process: What Happens When You Bring Your Device In
When you WhatsApp us on 064 529 5863 or book online at zasupport.com/book, we schedule you for a proper diagnostic appointment at our Hyde Park workshop. The assessment starts at R599 and typically takes 24 to 48 hours.
First, we perform a visual inspection: looking for signs of liquid damage, corrosion, burnt components, or physical damage. We check the charging port, inspect the battery connector, and examine the logic board under magnification. Next, we connect the device to our power profiling equipment, which tells us whether the device is drawing power and whether it's stuck in a boot loop or genuinely offline.
If the device draws power but won't display anything, we use external displays and recovery mode protocols to determine if the issue is software or hardware. If it draws no power at all, we test the power adapter, the USB-C charging cable, and the charging port. We then trace the power delivery pathway on the logic board to identify where the circuit fails.
This methodical approach means we rarely misdiagnose. A faulty port might look like a dead logic board to the untrained eye, but we catch it before ordering expensive parts.
Repair Costs and Turnaround for Sandton Clients
Our pricing is transparent and based on what actually needs fixing.
If the issue is a depleted battery or a faulty power adapter, repair costs between R399 and R899 and takes one to two working days. USB-C charging port replacement costs between R1,200 and R1,800, depending on the model and whether the port is soldered directly to the board. Software repairs—bootloader corruption or failed updates—cost between R299 and R599 and usually resolve within a few hours.
If liquid damage has affected the power circuit, we may recommend liquid damage restoration, which costs between R1,200 and R2,500 and takes three to five working days as components dry and we test the board methodically. Logic board component-level repair (for failed capacitors, voltage regulators, or power management ICs) costs between R1,500 and R3,200 and takes five to seven working days.
Full logic board replacement—genuinely rare for power issues—costs between R2,800 and R4,500 depending on the model year. We hold stock of logic boards for most popular models (MacBook Air M1/M2, MacBook Pro 13/14/16, Mac mini, iMac), so turnaround is often faster than sending the device away.
All repairs include a warranty: three years on parts and labour for logic board work, two years for battery and port replacement, and one year for software repairs. We've found this commitment reduces repeat visits and builds trust with Sandton professionals who can't afford downtime.
Why Choose ZA Support Over Mail-In Services
Sandton is 15 minutes from our workshop. Mail-in repair services from Pretoria, Cape Town, or Durban add three to five days to your timeline just for courier transit. You lose your device for a week or more, and if something goes wrong in transit, you have no recourse.
Our in-person diagnostics mean we catch edge cases that remote technicians miss. We've seen devices that appeared to have failed logic boards but actually had loose RAM or a disconnected battery ribbon—issues that only surface when you hold the device in your hands and test each component methodically. We've also fixed over 15,000 devices with logic board issues specifically by reheating solder joints and replacing capacitors, rather than swapping the entire board. Mail-in services default to board replacement because they lack the tools and time for component-level repair.
You get a detailed diagnostic report, a repair quote before work begins, and the option to collect your device the same day repairs finish if you're local. We also offer collection and delivery for Sandton residents who prefer not to travel to Hyde Park.
Logic Board Repair and When It's Necessary
If your device genuinely has a logic board fault—damaged power management IC, fried voltage regulator, or capacitor failure—component-level repair is faster and cheaper than board replacement. Our technicians have the training, schematics, and microscopy equipment to identify and replace individual components without disturbing the rest of the board.
This approach saves clients money and keeps their device running with its original board, which preserves hardware diagnostics and doesn't risk compatibility issues with newer repair batches.
Warranty and Ongoing Support
We stand behind our work. Three-year warranties on logic board repairs, and full support if something related to our repair goes wrong. We also provide load shedding advice—uninterruptible power supplies, surge protectors, and safe shutdown procedures that reduce the risk of repeat failures during Johannesburg's ongoing power cuts.

Frequently Asked Questions
Q: How long does a diagnostics appointment take?
A: The initial assessment takes about an hour. You drop off the device, we run power tests and visual inspections, and we contact you within 24 hours with a diagnosis and quote. Full diagnostics (which include bootloader testing and liquid damage assessment) take up to 48 hours.
Q: Can I fix "won't turn on" by force-restarting my Mac?
A: If your device isn't responding to the power button, a force restart (holding power + Command + Control for 10 seconds, then release and power on normally) sometimes works for software hangs. If this doesn't revive the device within a minute, the issue is likely hardware and you should get it assessed professionally.
Q: Is it always expensive to fix a Mac that won't turn on?
A: No. Most power failures we see are either depleted batteries (R499), faulty chargers (R599), or corroded ports (R1,200–R1,800). Logic board replacement is expensive, but it's also rare—less than 15% of our "won't turn on" repairs need full board replacement.
Q: How do I know if it's my power adapter or the device itself?
A: Bring your device to us. Our diagnostics will test the power adapter on multiple devices and the charging port with dedicated equipment. You'll have a clear answer in 48 hours rather than buying a new charger and hoping it fixes things.
Q: Do you repair all Apple devices or just MacBooks?
A: We repair MacBooks, Mac minis, iMacs, iPads, iPhones, and Apple Watches. Power-on issues affect all of them, and the diagnostics process is similar across models.
Q: What's your turnaround time for Sandton customers?
A: For battery and charger issues, one to two working days. For port replacement or software fixes, two to three days. For logic board work, five to seven days. We'll give you an exact date when you book your appointment.
