If your Mac shows “battery not charging,” check the charging cable, power adapter, and power source. Clean the charging port. Restart your Mac and reset the System Management Controller (SMC). Your Mac may pause charging to protect battery health. Look for battery-draining apps and ensure there are no connection issues.
Another aspect to consider is the battery health. Click on the Apple menu, select “About This Mac,” and then “System Report.” Under “Power,” check the cycle count and condition of your battery. If the condition indicates “Replace Soon” or “Service Battery,” it may need replacement.
Resetting the System Management Controller (SMC) can also help. This process can resolve various power-related issues, including a battery not charging on a Mac. To do this, turn off the Mac, then hold the Shift, Control, Option, and power keys simultaneously.
After following these steps, if the battery still does not charge, further investigation into software or hardware issues may be necessary. Understanding these quick fixes aids in efficiently addressing charging problems, leading to a smoother troubleshooting process.
Why Is My Mac Showing Battery Not Charging?
Your Mac shows “Battery Not Charging” if it is connected to power but does not increase its battery level. This message can indicate a few underlying issues that prevent the battery from charging properly.
According to Apple, a reputable source in technology, the battery status can display “Not Charging” for various reasons, and users should consider both hardware and software factors when troubleshooting this issue.
Several factors can cause the “Battery Not Charging” message on your Mac. The most common reasons include:
- Faulty Power Adapter: If the power adapter is damaged or not functioning properly, it may not deliver enough power.
- Cable Issues: A frayed or broken charging cable can disrupt the flow of electricity to the Mac.
- Battery Health: Over time, batteries lose their capacity. A degraded battery may not accept charging effectively.
- System Preferences: Sometimes, settings in macOS can inhibit charging when the device is in certain modes, like low power mode.
- Software Glitches: Temporary software issues can also prevent the battery from charging properly.
A technical term relevant to this issue is “power delivery”. Power delivery refers to the standard used for delivering power to devices. Malfunctions in the power delivery system can lead to charging issues.
The mechanisms or processes involved include how the Mac detects and manages power input from the adapter. When plugged in, the Mac’s internal circuitry assesses whether the battery can charge. If any of the previous issues are present, the system may determine that the battery cannot be charged and display the message accordingly.
Specific conditions that contribute to the “Battery Not Charging” issue are:
- Extreme Temperatures: Operating the Mac in very hot or cold environments can hinder battery performance.
- Age of Battery: A battery that has gone through many charge cycles may show decreased charging capability.
- Peripheral Devices: Connecting multiple high-powered peripherals can draw excess power from the adapter, restricting battery charging.
- System Overload: Running intensive applications while charging could result in the system exceeding power capacity.
Understanding these factors can help you diagnose and resolve the “Battery Not Charging” issue on your Mac effectively.
What Are the Common Causes of a Mac Battery Not Charging?
The common causes of a Mac battery not charging include issues related to the charger, the battery itself, software, and hardware malfunctions.
- Faulty charger
- Damaged charging cable
- Battery health degradation
- Software glitches
- Hardware issues
- External peripherals
- Power source problems
These factors can vary in severity and frequency, affecting different users in distinct ways. The following sections will explain each cause in detail.
-
Faulty Charger:
A faulty charger directly impacts the charging process for a Mac. A charger may malfunction due to wear and tear or electrical issues. Evidence from Apple suggests that third-party chargers might not support optimal charging, leading to performance inconsistencies. Additionally, a study by Consumer Reports (2018) indicates that many users experience problems with non-genuine chargers. Hence, using the original charger is highly recommended. -
Damaged Charging Cable:
A damaged charging cable can prevent a Mac from receiving power. Over time, cables may fray, break, or suffer from loose connections. Apple estimates that cable damage is a frequent issue encountered by users and suggests regular visual inspections. For instance, a case reported on MacRumors in 2019 detailed a user’s frustration after discovering hidden cable damage that went unnoticed. -
Battery Health Degradation:
Battery health degradation occurs as batteries age and their capacity to hold charge diminishes. Apple’s macOS includes a feature that displays battery health status. Once health drops below 80%, users may notice increased charging issues. According to a study by Battery University (2020), lithium-ion batteries, which Macs use, typically last between 500 to 1000 charge cycles, affecting their long-term performance. -
Software Glitches:
Software glitches can interfere with the charging process on a Mac. Updates or bugs within the macOS might cause the system to misinterpret battery status. A prominent case in 2021 highlighted that users experienced unresponsive charging indicators after a macOS update. Apple regularly releases patches to fix such issues, demonstrating the need for timely software updates. -
Hardware Issues:
Hardware issues affecting the Mac’s battery or logic board can hinder charging. These problems can stem from manufacturing defects or physical damage from drops. A report from iFixit (2019) noted that repairing internal components could sometimes solve charging issues, emphasizing the significance of expert assessments on hardware health. -
External Peripherals:
External peripherals connected to a Mac can draw power away from the battery. Devices like external monitors or high-power USB devices might limit charging capabilities. This situation was addressed in a 2020 post on TechRadar, which urged users to unplug unnecessary peripherals while charging to ensure maximum battery uptake. -
Power Source Problems:
Power source problems include issues with electrical outlets or power strips. A malfunctioning outlet can prevent the charger from functioning properly. Testing with different outlets can help identify this issue. In 2017, a user reported persistent charging problems that resolved upon switching to a different outlet, reinforcing this consideration.
Understanding these potential causes can help Mac users troubleshoot and address battery charging issues effectively.
How Can I Perform Basic Troubleshooting Steps for a Non-Charging Battery?
To troubleshoot a non-charging battery, follow these basic steps: check the power source, inspect the charging cable and port, restart the device, and calibrate the battery.
-
Check the power source: Ensure that the power source is functioning properly. Plug the charger into a different outlet or test the outlet with another device to verify it is providing power.
-
Inspect the charging cable and port: Examine the charging cable for frays or damages. Look for dirt or debris in the charging port that could impede connectivity. Cleaning the port with a dry cloth or using compressed air may help.
-
Restart the device: A simple restart can resolve many charging issues. Restarting refreshes the device’s software, potentially fixing minor glitches that prevent charging.
-
Calibrate the battery: Battery calibration can improve performance. Fully charge the device, then let the battery drain completely before charging it again. This process helps the device better understand its battery capacity.
By following these steps, you can effectively identify and resolve common issues associated with a non-charging battery.
