10 Steps to Fix a MacBook That Will Not Charge
Work through these steps in order. Each one eliminates a specific cause. If you reach step 10, the fault is board-level and needs professional micro-soldering — but most charging problems are resolved in the first five steps.
Step 1: Check the charger and cable
Inspect your charging cable from end to end. Look for fraying, kinks, exposed wiring, or burn marks near the connector. MagSafe cables are notorious for fraying where the cable meets the magnetic tip. USB-C cables can develop internal breaks that are invisible from outside. Try a different wall outlet — after load shedding in South Africa, individual outlets can be damaged by the return surge even if the breaker stays on. If you have access to a second charger, test with that. A working charger on a different Mac but dead on yours points to an internal Mac fault rather than the charger.
Step 2: Inspect the charging port
Use a torch to look inside the USB-C or MagSafe port. Pocket lint, dust, and debris accumulate over months and prevent proper contact. For USB-C ports, a wooden toothpick works well to gently clear compacted lint — never use metal tools as they can short the pins. For MagSafe, check for bent pins or dark residue that indicates liquid exposure. If you spot green or white corrosion, that is liquid damage and requires professional cleaning to prevent further board damage.
Step 3: Reset the SMC (Intel) or power cycle (Apple Silicon)
On Intel MacBooks (2019 and earlier, plus Intel models through 2020): shut down, then hold Shift + Control + Option + Power simultaneously for 10 seconds. Release all keys, then press Power to start up. On Apple Silicon Macs (M1, M2, M3, M4): shut down completely, wait 30 seconds, then press and hold the power button for a full 10 seconds. Release, wait a few seconds, and press power normally. This forces the power management controller to reinitialise and clears stuck charge states that software alone cannot fix.
Step 4: Check battery health in System Information
Click the Apple menu, hold Option, and click System Information. Go to Hardware then Power. Key values to check: Cycle Count (Apple rates batteries for 1,000 cycles), Condition (Normal, Replace Soon, Replace Now, or Service Battery), and Maximum Capacity. A battery below 80% capacity is considered consumed by Apple standards and may refuse to charge or hold charge intermittently. On macOS Ventura and newer, you can also check System Settings then Battery then Battery Health for a simplified view.
Step 5: Boot into Safe Mode
Safe Mode disables third-party kernel extensions and login items that can interfere with power management. On Intel Macs: restart and hold Shift until you see the login screen. On Apple Silicon: shut down, hold the power button until you see startup options, select your disk, then hold Shift and click Continue in Safe Mode. If the Mac charges normally in Safe Mode, a third-party app or driver is the culprit. Common offenders include fan control apps, battery management utilities, and VPN software with kernel extensions.
Step 6: Diagnose the MagSafe LED
The MagSafe LED is a direct indicator of what the charging circuit is doing. No light at all means zero power delivery — the charger, cable, or DC-in board is not making a connection. Amber (orange) means the battery is actively charging. Green means the battery is fully charged or nearly full. A flickering or intermittently flashing LED usually indicates a board-level fault, often a failing charging IC or a short on the power rail pulling the voltage down. If the light flashes once and goes out, suspect a short circuit on the logic board.
Step 7: Test both USB-C ports
On MacBooks with USB-C charging, try plugging the charger into each port individually. If one port charges and the other does not, the fault is a failed USB-C controller IC on the dead port side — typically the CD3215 (older models) or CD3217 (newer models). Each USB-C port has its own controller chip, so a single port failure is a discrete component fault, not a whole-board issue. If neither port charges, the fault may be upstream on the main power rail or the ISL9240 charger IC.
Step 8: Identify a charging IC fault
When all external checks pass but the MacBook still will not charge, the fault is almost certainly a failed charging IC on the logic board. The three most common culprits we see in our Hyde Park workshop: the CD3215 and CD3217 USB-C power delivery controllers that negotiate voltage and current with the charger, and the ISL9240 charger IC that regulates power from the USB-C controller to the battery. Load shedding surges in South Africa are the number one cause of these failures — the return-of-power spike exceeds the IC voltage tolerances. These are surface-mount components requiring micro-soldering to replace.
Step 9: Check for battery problems
A battery can fail in ways that prevent charging entirely. Swollen batteries (visible as a bulging trackpad or uneven base) must be replaced immediately as they are a fire hazard. Dead cells cause the battery management system to reject charge to protect the remaining cells. Connector damage — corrosion or a loose ribbon cable at the battery connector on the logic board — breaks the charge path. If your MacBook runs on mains power but the battery percentage never increases, or if it shuts down the moment you unplug, the battery itself needs replacement.
Step 10: Get a professional assessment
If you have worked through steps 1 to 9 without success, the fault requires board-level diagnosis. At ZA Support, we use thermal imaging and micro-soldering stations to pinpoint the exact failed component — whether that is a blown fuse, a shorted capacitor, a dead charging IC, or a damaged battery connector. Our R599 assessment includes a full written report identifying the fault, a fixed-price repair quote, and our No Fix No Fee guarantee. We collect from Sandton, Rosebank, Fourways, Bryanston, Midrand, Randburg, and surrounding Johannesburg suburbs.
When It Is a Charging IC Problem
In our experience at ZA Support, roughly 40% of MacBooks that arrive with "not charging" symptoms have a failed charging IC on the logic board. This is particularly common in South Africa where load shedding surges are a daily reality. Here are the three ICs we replace most frequently:
CD3215 / CD3217 — USB-C Power Delivery Controller
These Texas Instruments chips handle USB-C power negotiation on every MacBook from 2016 onwards. They communicate with the charger to agree on voltage (5V, 9V, 15V, or 20V) and current. A surge or liquid damage kills the negotiation, so the charger never delivers power even though the cable is physically connected. Symptoms: no charge from one or both USB-C ports, intermittent charging, or the Mac drawing power but not negotiating the correct wattage. The CD3217 is the newer variant found in M1 and later machines.
ISL9240 — Main Charger IC
The Renesas ISL9240 sits between the USB-C controller and the battery, converting the incoming USB-C power into the correct charging voltage for the battery cells. When this IC fails, the Mac may power on from mains but the battery percentage never increases — or it may not power on at all. This is the single most common IC failure we see after load shedding events. Replacement requires removing the old chip, reballing the pads, and soldering a new ISL9240 under microscope at our Hyde Park micro-soldering station.
When It Is the Battery
Not every charging problem is a board fault. Swollen batteries physically push against the trackpad and base — if your MacBook rocks on a flat surface or the trackpad clicks unevenly, check for swelling immediately. Dead cells prevent the battery management system from accepting charge. Corroded battery connectors (common after minor liquid exposure) break the charge path entirely. We test batteries as part of every R599 assessment and only recommend replacement when the cells or connector are genuinely faulty.
MacBook Charging Repair Costs in South Africa (2026)
Prices depend on the specific fault and MacBook model. Apple charges R15,000 to R55,000 for a full logic board replacement because they do not repair at component level. ZA Support repairs only the failed component, which is a fraction of the cost. All prices below are in ZAR and include our 12-month warranty.
| Repair Type | Cost (ZAR) |
|---|---|
| New genuine Apple charger (USB-C / MagSafe) | R1,200 – R2,499 |
