MacBook charging issues are one of the most common repairs we handle across Melbourne. Here's a systematic way to diagnose what's actually wrong.
Step 1: Check the Adapter and Cable
Apple USB-C cables and MagSafe adapters are genuinely fragile. Inspect the cable for any kinks, fraying or damage near the connector. Try a different cable if you have one. Try the charger in a different power outlet.
Step 2: Check the Charge Port
With USB-C MacBooks, pocket lint and debris accumulate in the charging port and prevent full contact. Use a wooden toothpick (not metal — you'll damage the port) to carefully remove any visible debris. A can of compressed air also helps.
Step 3: Reset the SMC
The System Management Controller handles power management on Mac. A stuck SMC can cause charging to stop working entirely. For M-series Macs: shut down, wait 30 seconds, restart. For Intel Macs with a T2 chip: shut down, hold Shift+Control+Option+Power for 10 seconds, release, start normally.
Step 4: Check System Information
Hold Option, click the Apple menu, choose System Information. Under Power, look at the Battery section. "Condition: Service Battery" means the battery needs replacing. "Cycle Count" above 1000 means the battery is near end of life. Check if it shows "Charging" when the adapter is connected — if it says "Not Charging," the battery is getting power but refusing to charge.
Step 5: Run on Charger Only
If the MacBook works fine plugged in but won't hold charge, the battery has failed. If it won't work even plugged in, the problem may be the charging circuit on the logic board — more serious but still repairable.
Common Battery Lifespan
MacBook batteries are rated for 1000 charge cycles. A once-daily charge gets you roughly 2.5–3 years before significant degradation. We carry stock for most MacBook models and can replace the battery at your home across Melbourne.
