Mac magsafe power adapter not charging.
If your macbook pro battery isn t charging the most likely place to check for trouble is in the magsafe charging cable.
A replacement adapter might not be the same size color shape or wattage as the original adapter that came with your computer.
The led on the adapter connector doesn t light up when attached to the computer.
Then reconnect the charging plug to the wall outlet then reconnect magsafe to the macbook pro.
If connecting a magsafe adapter to a macbook doesn t light up the power led chances are the socket you are connecting to is not working okay.
The adapter only charges the computer intermittently.
Let it sit unplugged from anything for about 5 minutes.
Inspect every inch of the cable.
Your power adapter won t charge the computer.
The adapter s white insulation separates from the magnetic end of the magsafe connector.
Maybe the adapter is not getting its power could be a loose socket or an improper connection.
Whatever the cause may be in most cases it s actually the adapter and not the magsafe connector.
It could be frayed broken or burned.
