Your MacBook is connected to the charger, but the battery percentage isn't increasing. Perhaps your MacBook Air says "Not Charging", your MacBook Pro only charges when you move the cable, or your MagSafe connector isn't working.

These problems can be frustrating, especially when you rely on your MacBook for business, university, remote working or everyday tasks.

The good news is that a MacBook not charging doesn't always mean you need a new laptop.

Charging problems can be caused by faulty cables, power adapters, USB-C ports, MagSafe connections, battery health settings or internal hardware faults.

At MIT Repair Centre in London, we help customers with MacBook, laptop and computer repair problems.

In this guide, we'll explain 10 common reasons why a MacBook stops charging, safe troubleshooting steps and when to consider professional MacBook repair in London.

1. Faulty USB-C Charging Cable

A damaged USB-C cable is one of the first things to check when your MacBook isn't charging.

Over time, charging cables can become damaged through bending, pulling or everyday use.

Common symptoms include:

• MacBook charging intermittently

• Charging stopping when the cable moves

• MacBook not recognising the charger

• Charging working with one cable but not another

• Visible damage to the charging cable

Before assuming your MacBook has a hardware problem, try another compatible charging cable.

Remember that not every USB-C cable supports the charging power required by your MacBook.

Apple recommends checking the cable and using an appropriate replacement when troubleshooting USB-C charging problems.

You can read Apple's official USB-C charging troubleshooting guide.

Professional Tip: If your MacBook only charges when you hold the cable at a particular angle, stop forcing the connection. The cable or charging port may be damaged.

2. MacBook USB-C Charging Port Not Working

If your MacBook still doesn't charge after testing another cable and adapter, the USB-C charging port may need attention.

A damaged USB-C connector can cause intermittent charging or prevent the MacBook from recognising the power source.

Common Warning Signs

• Loose USB-C connection

• Charging cable disconnecting easily

• Charging only at certain angles

• One USB-C port working while another doesn't

• Visible port damage

• Charging stopping unexpectedly

Dust or debris can also interfere with the connection.

Avoid inserting sharp or metallic objects into the port.

If you're searching for MacBook USB-C port repair near me, professional inspection can help identify whether the connector requires cleaning, repair or replacement.

3. MacBook MagSafe Charger Not Working

Some MacBook Air and MacBook Pro models use Apple's MagSafe charging connection.

If your MagSafe charger isn't working, possible causes include:

• Damaged MagSafe cable

• Faulty power adapter

• Debris around the magnetic connector

• Damaged charging contacts

• Power-related hardware faults

• Charging being temporarily paused

Check that the connector is clean and correctly attached.

If the cable or adapter is damaged, stop using it.

Apple provides additional troubleshooting guidance for MagSafe charging problems.

Read Apple's official MagSafe charging troubleshooting guide.

For persistent faults, professional diagnosis may be necessary.

4. MacBook Battery Says "Not Charging"

Does your MacBook show "Not Charging" even though the power adapter is connected?

This message doesn't always indicate a faulty battery.

MacBooks include battery-management features designed to help maintain battery health.

Depending on your model and macOS version, charging may be temporarily paused because of battery settings, temperature or power requirements.

A charger providing insufficient power may also allow the MacBook to operate without charging its battery.

Before replacing the battery, check whether the message is related to charging settings or a genuine hardware fault.

5. MacBook Battery Health Is Declining

Rechargeable batteries naturally lose capacity as they age.

If your MacBook battery has deteriorated, you may experience:

• Battery draining unusually quickly

• Unexpected shutdowns

• Reduced battery runtime

• Battery health warnings

• Charging problems

• MacBook switching off when disconnected from power

If your MacBook displays a "Service Recommended" battery warning, it may be time to investigate battery condition.

However, battery replacement should be based on the device's actual condition rather than age alone.

For customers searching for MacBook battery replacement London, MIT Repair Centre can discuss the symptoms and available repair options.

6. MacBook Charger Has Insufficient Wattage

Not every USB-C power adapter provides the same amount of power.

Some adapters may supply enough electricity to operate a MacBook but not enough to charge the battery efficiently.

For example, a charger designed for a smaller device may not be appropriate for a higher-powered MacBook Pro.

Always check the recommended charging specifications for your particular model.

Using a suitable charger and cable is especially important when troubleshooting slow charging.

7. MacBook Charging Stops at 80%

Does your MacBook charge normally but stop before reaching 100%?

This may be expected behaviour.

Apple provides battery-health features that can temporarily pause charging to help reduce battery ageing.

Temperature can also affect charging behaviour.

Before arranging a repair, check your MacBook's Battery settings.

If the battery consistently refuses to charge beyond a certain percentage and other symptoms are present, further diagnosis may be worthwhile.

8. MacBook Overheating While Charging

MacBooks can become warm during demanding tasks, but excessive heat can affect charging.

Possible contributing factors include:

• High CPU or GPU workload

• Restricted airflow

• Cooling-system problems

• Faulty charging accessories

• High ambient temperatures

• Internal hardware faults

If your MacBook becomes unusually hot, disconnect it from power if safe to do so and allow it to cool in a suitable environment.

Avoid using it on soft surfaces that restrict ventilation.

Persistent overheating should be investigated rather than ignored.

9. MacBook Software or Power Management Problem

Sometimes charging behaviour is related to software or power management.

Try restarting your MacBook.

If the device is working normally and an appropriate update is available, check for macOS updates after backing up important files.

For Apple silicon MacBooks, a normal restart is often an appropriate initial troubleshooting step.

Older Intel-based MacBooks may have different power-management troubleshooting procedures.

Avoid following random reset instructions without confirming they apply to your model.

10. Internal Charging Circuit or Logic Board Fault

If the charging cable, adapter, port and battery have been checked, the problem may involve internal hardware.

Potential faults can affect power-management components, internal connectors or the logic board.

These problems generally require specialist diagnosis.

A MacBook that won't turn on or charge should not automatically be assumed to need a complete logic board replacement.

The appropriate repair depends on the actual fault.

MacBook Air, MacBook Pro and MacBook Neo Charging Problems in 2026

Apple's MacBook lineup has expanded, and different models have different charging configurations.

The 2026 MacBook Air with M5 supports MagSafe 3 and USB-C charging.

The MacBook Neo, introduced in March 2026, uses USB-C charging.

MacBook Pro models may support MagSafe, USB-C or both, depending on the model and year.

This matters because the correct charger, cable and troubleshooting process depend on the exact MacBook model.

Whether you have an older Intel MacBook or a newer Apple silicon model, identify the device before purchasing replacement charging accessories.

MacBook Not Charging? What Should You Check First?

Before booking a repair, try these basic checks:

1. Confirm that the wall socket works.

2. Inspect the charging cable for damage.

3. Try a compatible power adapter.

4. Check the charging connector for visible debris.

5. Restart your MacBook.

6. Check Battery settings if the device starts normally.

7. Allow an overheated MacBook to cool.

8. Check whether another supported charging port works.

9. Back up important data whenever possible.

10. Arrange professional diagnosis if charging problems continue.

Important: If the battery is swollen, the device has suffered liquid damage, or the charging components show signs of burning or overheating, stop using the affected equipment and seek professional assistance.

How Much Does MacBook Charging Port Repair Cost in London?

The cost of MacBook charging repair depends on several factors.

These include:

• MacBook model and year

• Type of charging connector

• Nature of the fault

• Availability of replacement parts

• Whether internal components are damaged

• Whether battery replacement is required

A damaged cable is a different problem from a faulty USB-C port or internal charging circuit.

For this reason, it's best to get the problem diagnosed before assuming a particular repair is necessary.

Contact MIT Repair Centre with your MacBook model and symptoms to discuss the available options.

Is It Worth Repairing a MacBook That Won't Charge?

In many cases, repairing a charging problem can be worth considering.

If your MacBook otherwise works well, replacing the entire laptop may not be necessary.

Before making a decision, consider the device's age, performance, condition, repair estimate and remaining software support.

A charging fault alone doesn't automatically mean the MacBook has reached the end of its useful life.
