Are you facing issues with your macbook battery not charging, macbook not charging, or macbook pro not charging? You’re not alone. There can be several reasons why your MacBook, MacBook Pro, or MacBook Air battery might stop charging.
Some common issues that users face include older batteries that have gone through too many charge cycles and can no longer hold as much charge as before. Defective power adapters or charging ports that are damaged or not connecting properly are also a frequent cause.
Software glitches from new system or app updates sometimes interfere with charging capabilities as well. Hardware failures like a faulty SMC (System Management Controller) or charger component are varioushardware problems that can prevent charging.
This article will explore these and other most frequent causes of a mac battery not charging, battery is not charging macbook pro, and macbook air not charging in more depth. It will also provide some easy troubleshooting tips and step-by-step solutions to help you fix these charging issues, to get your MacBook up and running again charging problems resolved.
Reasons why MacBook Batteries Stop Charging
Aged Battery Capacity
As MacBook batteries go through their use lifespan, their ability to hold a full charge decreases. Apple rates the average battery as maintaining around 80% of its original capacity after 500 complete charge cycles. Surpassing this number can significantly diminish the battery’s effectiveness.
Tell-tale signs include needing to recharge more frequently or not powering the MacBook for as long as when it was new. Battery diagnostic tests in macOS can check maximum charge percentage and cycle count to determine if age is a factor in charging issues.
Damaged Charging Port or Cable
The charging port located on the MacBook is vulnerable to damage from everyday use. Bent or broken pins inside from accidental impact can disrupt conductivity and cause macbook not charging problems. Frequent disconnecting/reconnecting of the power cable also makes the charging pins prone to wear down more quickly.
Inspect the port closely for any damage or buildup of lint/debris which could block a proper connection. The cable itself can develop fraying of internal wires or cracks in the casing from regular flexing. Kinks or breaks in the cable potentially reduce current transfer and positively impact charging.
Water Damage
A water damaged MacBook might pose a serious risk to its battery charging ability. Liquid that seeps inside near the charging port or battery can corrode delicate internal components over time. Even seemingly small amounts of moisture penetration from accidental spills or exposure to high humidity environments could potentially disrupt conductivity and prevent charging.
MacBook batteries are designed to provide power safely and resist water intrusion to an extent, though sustained submersion is never recommended as it can inevitably lead to costly repairs if charging becomes impaired. Careful handling and storing of the device in dry conditions helps avoid exposure to water risks that may surface later as unusable or non-charging battery functions.
Overheating Battery Issues
If a fully drained battery gets excessively hot without any cooling, it may permanently lose capacity quicker than normal degradation. This makes an already empty, hot MacBook prone to mac battery not charging errors. Heat damages the battery’s internal chemical composition over time. Keeping air vents unblocked and providing ventilation when charging helps stabilize the battery temperature. Avoid leaving your MacBook in very warm environments without the ability to properly cool down in between uses.
MacBook Battery Issues
Software and Firmware Incompatibilities
Bugs can sometimes emerge when upgrading to a new version of macOS that interfere with normal charging behavior. This might cause macbook battery not charging or macbook pro not charging issues until the next software update. Be sure all software, including third-party apps, and firmware are using the most up-to-date versions.
Reset System Management Controller
The SMC is responsible for communicating battery levels and power states. An SMC reset clears parameter RAM (PRAM) and can resolve potential glitches. To reset the SMC on most MacBooks, hold the power button for 10 seconds. This addresses possible power management or battery charging detection faults.
Battery Calibration
If your MacBook seems to inaccurately estimate charge percentages, the battery calibration may need refreshing. The terminal command ‘calibratePower’ triggers a battery recalibration. This helps ensure the Mac can accurately detect charging levels to avoid premature charging cutoff or other odd behaviors.
Physical Battery Replacement
In rare cases of persistent charging issues, the battery itself may need replacing. Faults such as failed temperature sensors could signal the battery has reached the end of its design lifespan. An Apple Store can test battery health and perform a physical replacement if needed to fully resolve troubles charging.
Charging issues with Different MacBook Models
MacBook Air Charging Issues
The MacBook Air’s thin, tapered charging port is more susceptible to buildup of lint and dust particles which can interfere with connectivity. Use compressed air to clear any obstructions. Its internal battery is also not designed for frequent replacement so proper care is important. Make sure the power adapter is fully seated when charging.
MacBook Pro Charging Issues
Only use the charger that came with your MacBook Pro as third party adapters may provide improper voltage. Inspect the MagSafe port for damage like bent pins if using an older Pro model without USB-C. The discrete graphics in higher-end Pros generate more internal heat under load – ensure adequate ventilation when charging to keep the battery within its optimal temperature range.
MacBook Charging Issues
Vintage MacBook and MacBook Pro models had user-replaceable MagSafe batteries that may need replacement over time. Batteries are now built-in on newer versions so any issues require Apple hardware service. Carefully check the charging cable and MagSafe port connection for breakdown or debris if charging stops working. Reset the SMC and try a battery recalibration as previously mentioned.
Resolving Persistent Charging Problems
Apple Support Consultation
If issues remain after thorough troubleshooting, contact Apple Support by phone or online chat. Explain each step taken and when the problem occurs. An Apple Genius can assist with more specific hardware testing or isolating any software bugs through remote diagnostics. Apple expertise helps pinpoint charging failures needing attention.
Independent Repair Shops
For older MacBooks past warranty, licensed third-party MacBook battery repair shops provide affordable battery, port and cable replacements. Certified technicians have Apple training and source genuine components. Some issues like a worn charging port can be fixed inexpensively this way. Assurance programs also cover repairs against future defects.
Whole Logic Board Replacement
In rare cases of severe charging system faults, replacing the system logic board containing power management circuits becomes the only option. Apple handles this as a repair estimate if the cost seems justified compared to a replacement MacBook purchase. It effectively renews all internal hardware at once.
Precision Calibration Services
A specialist battery calibration service can precisely test an individual battery cell’s capacity and discharge limits. This deep-dive analysis identifies hidden weaknesses causing inconsistent charges that simple recalibration misses. It warrants consideration for frequent charging complaints.
Resolving Your MacBook Charging Issue
With preventative care and proper troubleshooting techniques, MacBook batteries should maintain good health and charging capacity for several years of use. However, normal wear and unexpected technical issues do occasionally cause charging to stop working as it should.
This guide has covered the most common potential causes of macbook battery not charging, from aged batteries and physical damage to software bugs and hardware faults. Along the way, steps were provided to methodically test for these issues, refurbish battery calibration, and reset secondary systems like SMC that could be contributing factors.
For stubborn charging problems, further assistance from Apple support experts, licensed independent shops or precision services are available. Understanding how battery technology, charging systems work, and following repair best practices will help fix your charging problems and get you back up and running quickly.
