macbook充電

Forgetting to charge your MacBook properly overnight can leave you with a headache in the morning. And if you’re troubleshooting a broken MacBook, checking if it’s able to charge is one way to rule out battery issues.

忘記在一夜之間為MacBook正確充電，可能會讓您頭疼。 而且，如果要對損壞的MacBook進行故障排除，則檢查它是否可以充電是排除電池問題的一種方法。

較舊的Macbook的充電電纜上有燈 (Older Macbooks Have Lights on the Charging Cable)

If your MacBook was made before 2016 and has a magnetic charging cable (even the “old” L-shaped one), it will have a light on the end of the cable indicating that it is charging. If the light is orange, you’re charging. If it’s green, your battery is full, and you’re running off the power adapter. Even if it doesn’t turn on, it should still have the light if the problem isn’t with the battery.

如果您的MacBook是在2016年之前制造的，并且具有磁性充電電纜(甚至是“ L型”舊款)，則電纜末端會亮起，表明正在充電。 如果指示燈為橙色，則說明您正在充電。 如果為綠色，則表明電池已充滿，并且正在用電源適配器供電。 即使它沒有打開，如果不是電池問題，它也應該仍然亮著。

If you have a new MacBook with a USB Type C charger, it’s a different story. The USB-C charger doesn’t have the indicator light, meaning if your MacBook doesn’t turn on, you may have no idea if the battery is the cause, or if your cable is just broken.

如果您有一臺帶USB C型充電器的新MacBook，那就另當別論了。 USB-C充電器沒有指示燈，這意味著如果MacBook無法打開，您可能不知道是電池造成的，還是電纜剛剛斷開。

If you have a really old cable, or a third party one, you may be missing the light as well.

如果您的電纜真的很舊，或者是第三方電纜，則也可能會丟失光。

One way to check when troubleshooting a USB C cable without a light is to leave it plugged in for a while and check if the power brick gets warm. They generate heat while charging, so if it’s not charging, it will be cold.

故障排除時，檢查USB C電纜不帶燈的一種方法是將其插入一段時間，然后檢查電源磚是否變熱。 它們在充電時會發熱，因此如果不充電，則會變冷。

Another thing you can try is shining a flashlight on the Apple logo on the back. If you can see something onscreen, it means your backlight is broken (a fairly common problem, often mistaken for it not turning on at all) and you should find an Apple Store. Or, maybe you’ve turned down the brightness all the way, and your MacBook is fine.

您可以嘗試的另一件事是在手背的Apple徽標上閃爍一個手電筒。 如果您在屏幕上看到一些東西，則說明您的背光燈壞了(這是一個很常見的問題，常常被誤認為根本沒有打開)，您應該找到一個Apple Store。 或者，也許您已經完全降低了亮度，而MacBook還是不錯的。

Tip: Newer MacBooks make a sound when you connect the charger. It’s a ding that sounds just like the sound when plugging in an iPhone, but it’s quieter. You also won’t hear it if your laptop’s sound is off or if the battery is completely dead when you plug in the cable. Still, you can try disconnecting and reconnecting the cable to listen for the sound. If you hear it, then you know it’s charging.

提示：連接充電器時，較新的MacBook會發出聲音。 聽起來像是插入iPhone時的聲音，但它更安靜。 如果您的筆記本電腦的聲音已關閉或插入電纜時電池完全沒電，您也不會聽到它的聲音。 不過，您可以嘗試斷開連接并重新連接電纜以收聽聲音。 如果您聽到它，則說明它正在充電。

屏幕可見嗎？ (Is It Turned On, With the Screen Visible?)

If so, the battery status is displayed in the top menu bar, along with apps using a lot of juice and warnings if your battery is old (and not holding a charge very well). If your battery is charging, it will have a lightning bolt symbol over the battery icon.

如果是這樣，則電池狀態會顯示在頂部菜單欄中，同時使用大量果汁的應用程序也會顯示在屏幕上，并會在電池陳舊(如果充電不充分)時發出警告。 如果您的電池正在充電，則電池圖標上將帶有一個閃電符號。

If you don’t see the icon in the menu bar, it may be turned off. Open up the System Preferences app and click on the “Energy Saver” icon shaped like a lightbulb. At the bottom should be “Show battery status in menu bar.” Make sure this is checked.

如果您在菜單欄中沒有看到該圖標，則可能已將其關閉。 打開系統偏好設置應用程序，然后單擊形狀像燈泡的“節能器”圖標。 底部應該是“在菜單欄中顯示電池狀態”。 確保已選中。

You can also adjust other power-related settings from here, including how quickly your display will turn off when not in use.

您還可以從此處調整其他與電源相關的設置，包括不使用顯示器時關閉顯示器的速度。

If all of this fails and you’re still having issues with a busted MacBook, it’s probably best to consult your local Apple Store for repairs.

如果所有這些都失敗了，而您仍然無法解決MacBook破損的問題，那么最好咨詢當地的Apple Store進行維修。
