The MacBook Pro has a really long battery life, but eventually
you need to charge it. But for some owners of the newest MacBook
Pro, that isn't possible. Several users on Reddit have posted that the laptop fails to
charge properly when connected to the 140W MagSafe power
The issue is apparently limited to the 16-inch MacBook Pro and
the 140-watt power adapter, which is included with the device for
fast charging. The problem occurs when the MacBook Pro is shut down
and then the MagSafe power adapter is connected. The laptop will
make a ping sound and the connector's LED flashes in a continuous
loop. The battery doesn't get charged when this happens, but if the
battery is above 80 percent, then the error stops.
Editors at our sister publication MacWelt in Germany experienced the same

or putting the MacBook to sleep, and isn't a permanent or ideal

laptops displaying the issue are able to charge when shut down
using a USB-C cable instead of MagSafe. The user u/_Trillionaire_,

lid open as a workaround.
The user u/_Trillionaire_ was initially told by Apple Support to
boot into Recovery Mode and then restart the
Mac again, but this provided only a temporary fix.
Several users on Reddit posted that they have taken the laptop
to the Apple Store for consultation and have been told that Apple
is aware of the problem and is investigating. Some users said that
after visiting the Apple Store, they were contacted by Apple to get
more information about the problem. And others were offered
We'll update this article with any new information when it
