Is It Turned On, With the Screen Visible? If you hear it, then you know it’s charging. Still, you can try disconnecting and reconnecting the cable to listen for the sound. 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. It’s a ding that sounds just like the sound when plugging in an iPhone, but it’s quieter. Tip: Newer MacBooks make a sound when you connect the charger. Or, maybe you’ve turned down the brightness all the way, and your MacBook is fine. 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. They generate heat while charging, so if it’s not charging, it will be cold.Īnother thing you can try is shining a flashlight on the Apple logo on the back. 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. If you have a really old cable, or a third party one, you may be missing the light as well. 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. If you have a new MacBook with a USB Type C charger, it’s a different story. Even if it doesn’t turn on, it should still have the light if the problem isn’t with the battery. If it’s green, your battery is full, and you’re running off the power adapter. 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. Older Macbooks Have Lights on the Charging Cable
