What Should You Do if Your Macbook Charger Stops Working?

When Should I Replace My MacBook Charger?

There is no hard and fast rule for when you should replace a MacBook charger. Most chargers are relatively sturdy pieces of equipment that should last for several years unless there is damage or an obvious flaw in their design.

When it comes to battery life, many tech experts will likely tell you that laptop batteries are good for at least five years.

Most batteries are rated to provide a good charge for a certain number of cycles before degrading in terms of holding or receiving a full charge. These are simply guidelines that each company follows to ensure the bare minimum of battery functionality.

As a result, they may replace one for you under certain warranty conditions, but only if it isn't due to negligence or damage outside of normal operations that are causing it to fail to hold a charge for the recommended cycles.

Chargers or adapters function differently than the batteries to which they provide energy. Chargers, unlike batteries, do not have expiration dates. This means they can work at a perfectly acceptable level for many years even if they show signs of surface wear and tear.

Any part that has things you'll need to plug in or unplug on a regular basis can wear out over time, and it's possible that your MacBook charger will eventually fail. However, if the charger is properly connected to the laptop and you can see that the battery is charging, the component is most likely still functional for your needs.

Although a slower charging process could indicate a problem with the power adapter, it is more likely that you will encounter a problem with the battery before the charger.

There are other indicators to look for, but if you plug the computer into the factory charger and discover that the battery is receiving no energy from the outlet, it may be a good indication that the charger needs to be replaced.

How long do MacBook Charges Last?

You can expect your MacBook to last for many years if you do not receive a defective charger with it and if it is not subjected to any kind of abnormal abuse.

Some consultants who have worked for Apple in some capacity for decades have never seen a charger fail. The common thread in these cases is that the charger, particularly the cable, should not be abused. Connect the device to the wall outlet in a straight line to ensure a secure connection.

Always hold the charger near the port and gently pull it out. Never yank the cable to disconnect the charger from the wall or the MacBook. If you follow these simple guidelines, your charger should last for decades.

What Should You Do if Your Macbook Charger Stops Working?

If your USB-C power adapter isn't charging your MacBook, unplug it from the power outlet, wait a few seconds, and then plug it back in. If that doesn't work, try these suggestions.

  • Checkpower

Learn how to inspect your AC plug and power outlet.

  • Checkthe Ac Plug or Cable

Your power adapter includes a detachable AC plug with blades that you insert into an electrical outlet.

If your Mac notebook does not charge when using the power adapter's AC plug, try another Apple AC plug or an Apple Power Adapter Extension Cable (sold separately).

  • Check the Power Outlet

Check that your USB-C power adapter is plugged into a working power outlet. Unplug your USB-C power adapter from the wall outlet, then plug in a known good device, such as a lamp or clock, to ensure it works properly.

If the power outlet is operational, plug in your USB-C power adapter and attempt to charge your Mac. If your Mac still won't charge, restart it and close the display for 30 seconds before opening it and attempting to charge it again.

  • Look for Issueswith Line Noise

Unplug the power adapter from the wall, then wait 30 seconds before plugging it back in:

  1. If your Mac notebook begins charging after you reconnect the power adapter, it could be due to line noise (disruption caused by stray electromagnetic signals) from your power outlet. When the power adapter's built-in voltage protection detects line noise from an outlet, it shuts off immediately.
  1. Lights with ballasts, refrigerators or mini-refrigerators on the same electrical circuit as the outlet you're using are all potential sources of line noise. Plugging the power adapter into a different circuit or an uninterruptible power supply (UPS) can help.

If your power adapter continues to turn off when plugged into a known good outlet, take it to an Apple Authorized Service Provider or Apple Store for further evaluation.

  • Check the Cabling

A USB-C cable is included with your Mac notebook to charge it. You can test another USB-C cable to see if this one is causing your charging problem. Keep in mind that not all USB-C cables can charge your MacBook, so make sure the cable you use is intended for charging.

If your Mac notebook charges with one USB-C cable but not another, stop using the cable that doesn't work right away and have your cable and power supply checked.

If your Mac notebook only starts charging when you wiggle or move the USB-C cable or Apple Power Adapter Extension Cable (sold separately), stop using it right away and have your cable and power supply checked.

  • If the Adapter Becomes Hot

The USB-C power adapter can get hot during typical use, so keep it in a well-ventilated environment. When using the Power Adapter Extension Cable, always plug the power adapter directly into a power outlet using the AC plug, or position it on a table or other well-ventilated area.

Avoid placing your adaptor in a place with inadequate ventilation, such as on a couch, thick carpeting, bedding, or a pillow. Covering the adapter with a blanket or other insulation is not recommended.

If the power adapter gets too hot, it may shut off. If this occurs, unplug the USB-C connection from your Mac notebook and wait for the power adapter to cool before touching it.

  • If You Notice a Spark

When you insert the USB-C power adapter, it may ignite where the plug's blades enter the outlet. This is common and can occur when you plug any electrical item into a power socket.

If you see any of the following symptoms after plugging in your adapter, or if you have any other concerns about sparking, please contact Apple:

  1. Contact Apple if the spark comes from somewhere other than the plug's blades.
  2. If you notice any damage or discoloration on the adapter, please contact Apple.

How Long Does It Take to Charge My Macbook?

Your MacBook battery is lithium-ion. There are two ways for charging these batteries: quick charge and trickle charge. When your battery is entirely discharged, the charger will use a high charge voltage and amperage to recharge it to roughly 80% capacity in about 2 hours. The charging voltage and amperage progressively drop after two hours until your battery is fully charged. This second stage, known as trickle charging, takes around 2 hours.
