根据我们的经验，Apple MacBook(Apple MacBooks)是您能买到的最可靠的电脑之一。除非您可以看到才华横溢的Louis Rossman解释的奇怪的糟糕设计决策，否则大多数人发现他们的MacBook(MacBooks)只是不停地卡车运输。这就是设备严重故障可能令人震惊的部分原因。前一分钟你的MacBook工作得很好，下一分钟就没有充电了！
MacBook 无法充电的原因有很多。有些您可以自己修复，有些则需要Apple或经过认证的第三方维修公司来解决。让我们回顾一下常见原因和修复方法，看看您的特定问题会是哪一个。
MacBook“不充电(Charging)”的两种类型
“ MacBook未充电”可能意味着一些事情。最常见的情况是，您插入充电电缆后，即使您已接通电源，MacBook也无法开机，或者电池一直在耗尽电量。(MacBook)
有人可能想要搜索此问题的第二个原因是电池状态下显示“未充电”的消息。然而，计算机工作正常，电池电量不会下降，下降得更慢，或者实际上会随着时间的推移缓慢增加。
第二种情况发生在MacBook需要消耗的电量超过通过电缆提供的电量时。通常这是因为您使用的电源适配器功率不足。我们很快就会解决这个问题，但首先让我们看看如果您的MacBook完全死机并且无法充电，您可以做些什么。
1. 我的 MacBook 坏了
如果您的MacBook无法开机或即使在您接通电源后也无法充电，那么您手上的MacBook可能已经死机了。(MacBook)但是，在您将其运送到Apple Genius之前，您可以尝试以下几点：
- 按住电源按钮(power button)10 秒钟，这将强制MacBook关机。然后尝试像往常一样打开它。
- 执行此操作后仍然没有响应，您可以尝试重置SMC（系统管理控制器）。(System Management Controller)按住键盘左侧的Shift-Control-Option和电源按钮 10 秒钟。(Shift-Control-Option)然后松开按键并尝试正常打开MacBook电源。(MacBook)
如果这不起作用，您应该打包笔记本并将其带到最近的服务中心进行评估。解决了这个最严重的问题，我们现在可以看看MacBook用户面临的更常见（也更可修复！）的充电问题。
2. 从源头开始：检查您的充电器
如果你的MacBook(MacBook)没有充电，这个难题有两个部分。一个是笔记本电脑本身，另一个是充电器。后一块硬件是最容易检查的，因此从那里开始是有意义的。
确保(Make)充电器、它的电缆和连接器没有任何明显可见的损坏。您还应该通过尝试使用其他设备来检查壁式插座以确保其正常工作。
如果充电器是USB型号，请尝试将其插入另一个USB设备。如果充电器适用于其他设备但不适用于您的 MacBook，则可能不是问题的原因。
3.使用原装苹果配件
现代MacBook(MacBooks)的用途特别广泛，因为它们使用标准USB-C端口进行充电。这意味着您几乎可以使用任何智能手机或平板电脑充电器为您的笔记本电脑充电。即使是移动电源也可以延长您在灯熄灭之前可以离开电源的时间。
不幸的是，世界上到处都是低质量的充电设备，或者不能正确遵守MacBook所需的供电标准的充电设备。也可能是充电器根本没有为MacBook提供足够功率所需的功率。
MacBook充电器的功率范围从 29W 到大约 96W，因此请检查您的MacBook需要哪款，并使用相同或更高级别的充电器。您可以使用 18W 智能手机充电器为MacBook充电，但计算机必须关闭或处于睡眠状态。即使这样，一路充电也需要更长的时间。
消除此问题的最佳方法是使用笔记本电脑随附的原装Apple充电器和电缆。(Apple)如果这些也给你一个“不充电”的错误，那么是时候让苹果(Apple)维修中心检查一下了。
4.你有脏端口吗？
请(Please)不要个人认为，很多人都有脏端口。这没什么好丢脸的！重要的是检查 MacBook 充电端口中积聚的灰尘和棉绒是否可能导致电气连接不良。
对于之前的Thunderbolt 3 (Thunderbolt 3) MacBook(MacBooks)来说，这并不是真正的问题，但如果您拥有较新的型号之一，那么它们通常会遇到与Thunderbolt 3和 USB-C 端口相同的问题。向港口照射一盏灯，看看那里是否有污物。如果是这样，您可以让技术人员为您清理它们，或者，如果您更勇敢一点，可以用塑料或木制牙签轻轻地从连接器上挑出污垢。与往常一样，这样做需要您自担风险。
5. 你的电池实际上可能没电了(Might)
锂电池(Lithium batteries)每次经过充电周期都会磨损一点。在完成额定循环次数后，电池开始失去容量，这个过程可能开始缓慢然后加速。在某些时候，电池不会充电或保持如此微小的电量，以至于几分钟内就死机了。如果您在MacOS(MacOS)中单击电池图标并看到“维修电池”消息，则表示电池需要由专业人员检查并且很可能已更换。
在取出电池时，这里有三种可能性。较旧型号的MacBook具有用户可更换的电池。您只需弹出旧电池并插入新电池即可。在这些MacBook(MacBooks)之后出现了一代笔记本电脑，可以取出电池，但这涉及打开笔记本电脑。如果您有其中一种型号，请前往iFixit 指南(iFixit guide)，了解获取该电池所涉及的内容。
最新型号的MacBook是密封单元，即使您打开它，电池也会粘在里面，需要用溶剂将其取出。这会迫使您使用Apple技术人员，并剥夺您自己完成工作的能力，除非您碰巧拥有合适的技术技能。
保持负责
希望您的MacBook充电问题只是暂时的。如果没有，最终由经过认证的技术人员安装新电池并不会那么昂贵。(that )
你永远不应该让别人为你的MacBook安装非 Apple 更换电池。大多数时候，使用非品牌锂电池是个坏主意，但对于经过精心设计的MacBook来说尤其如此。(MacBooks)制造精度较低的电池存在着火或爆炸的风险。这将比由合适的人更换正确的电池要昂贵得多！
MacBook Not Charging? 5 Possible Fixes
In our expеriеncе, Apple MacBooks are some of the most reliable computers you can buy. Barring the odd poor design decisions you can see explained by the brilliant Louis Rossman, most people find that their MacBooks just keep trucking. That’s part of the reason a serious failure of the device can come as a shock. One minute your MacBook is working just fine, the next it’s not charging!
There are a number of reasons why your MacBook might not be charging. Some you can fix yourself, others will require Apple or a certified third-party repair company to address. Let’s go over the common causes and fixes to see which one your particular problem will turn out to be.
The Two Types of MacBook “Not Charging”
There are a few things “MacBook not charging” can mean. The most common is that you plug in the charging cable and your MacBook doesn’t turn on or the battery keeps draining even though you’ve hooked up the power.
The second reason someone might want to search this issue is a message under battery status that says “not charging”. Yet the computer is working normally and the battery level doesn’t fall, falls more slowly, or actually increases slowly over time.
This second situation happens when the MacBook needs to draw more power than is being provided through the cable. Usually that’s because you’re using a power adapter with insufficient wattage. We’ll get to this issue shortly, but first let’s look at what you can do if your MacBook is completely dead and won’t charge.
1. My MacBook is Dead
If your MacBook won’t turn on or won’t charge even when you connect power to it, you may have a dead MacBook on your hands. Before you cart it off to an Apple Genius however, here are a few things to try:
- Press and hold the power button for 10 seconds, which will force the MacBook to power down. Then try turning it on as usual.
- After doing this and there’s still no response, you can attempt a SMC (System Management Controller) reset. Hold Shift-Control-Option on the left side of the keyboard along with the power button for 10 seconds. Then release the keys and try powering on the MacBook as normal.
If that doesn’t work, you should pack up your notebook and take it to the nearest service center to be evaluated. With this most serious issue out of the way, we can now look at the more common (and more fixable!) charging issues MacBook owners face.
2. Start at the Source: Check Your Charger
There are two parts to the puzzle if your MacBook isn’t charging. One is the laptop itself and the other is the charger. The latter piece of hardware is the easiest to check, so it makes sense to start there.
Make sure that the charger, it’s cables and connectors don’t have any obvious visible damage. You should also check to make sure that the wall outlet works by trying a different appliance with it.
If the charger is a USB model, try plugging it into another USB device. If the charger works with other devices but not your MacBook, it’s probably not the cause of the issue.
3. Use Original Apple Accessories
Modern MacBooks are especially versatile because they use a standard USB-C port to charge. This means that you can use just about any smartphone or tablet charger to juice up your laptop. Even a powerbank can extend how long you can be away from power before the lights go out.
Unfortunately, the world is full of low-quality charging devices or ones that don’t stick properly to the power delivery standards that the MacBook needs. It may also be that the charger simply doesn’t have the wattage required to give the MacBook enough power.
MacBook chargers range from 29W to about 96W, so check which your MacBook requires and use something at the same or higher level. You can charge a MacBook with an 18W smartphone charger, but the computer will have to be off or asleep. Even then it will take much longer to charge all the way.
The best way to eliminate this as the cause of the issue is to use the original Apple charger and cable that came with the notebook. If these also give you a “not charging” error then it’s time to have things checked out by an Apple repair center.
4.Do You Have Dirty Ports?
Please don’t take it personally, lots of people have dirty ports. It’s nothing to be ashamed of! What’s important is that you check whether dust and lint building up in your MacBook’s charging port may be responsible for a poor electrical connection.
This isn’t really an issue for pre-Thunderbolt 3 MacBooks, but if you have one of the newer models then they can suffer the same issues as Thunderbolt 3 and USB-C ports in general. Shine a light into the port to see if there’s filth in there. If so, you can either have a technician clean them out for you or, if you’re a little more brave, gently pick out the dirt from the connector with a plastic or wooden toothpick. As always, do this at your own risk.
5. Your Battery Might Actually be Dead
Lithium batteries wear out a little every time they go through a charge cycle. After they’ve gone through their rated number of cycles, the battery starts to lose capacity, a process that might start slowly and then accelerate. At some point the battery won’t charge or holds such a tiny charge that it’s dead in minutes. If you click on the battery icon in MacOS and see a “service battery” message, it means that the battery needs to be checked by a professional and most likely replaced.
There are three possibilities here when it comes to taking out the battery. Older models of MacBook have user-replaceable batteries. You simply pop out the old battery and slot a new one in. After these MacBooks came a generation of laptops where the battery could be removed, but this involved opening up the laptop. If you have one of these models, head over to the iFixit guide to see what’s involved in getting to that battery.
The latest models of MacBook are sealed units and even if you got it open, the battery is glued in and needs to be removed with solvent. This forces you to use an Apple technician and takes away your ability to do the work yourself unless you happen to have the right technical skills.
Stay in Charge
Hopefully your MacBook charging problem has turned out to be a temporary one. If not, ultimately it’s not that expensive to have a new battery installed by a certified technician.
What you should never do is have someone fit a non-Apple replacement battery to your MacBook. Using off-brand lithium batteries is a bad idea most of the time, but it’s especially true of MacBooks, which have been carefully engineered. A less precisely made battery runs the risk of fire or explosion. That’s going to be much more expensive to fix than getting the right battery replacement done by the right person!
