Always be careful with your computer’s battery. Once you’ve got it out, set it aside someplace where it won’t be dropped or have something spilled on it.

It’s important that the object you use be completely dry. Never apply cleaning sprays or any other liquids to your computer’s open connections. [6] X Research source Make sure the toothbrush or cotton swab is clean to avoid transferring dirt and other substances. Avoid using metal objects, such as paperclips, inside the charging port. Not only can this interfere with the port’s magnetic properties, it’s also an electrical hazard.

Scrub vigorously to remove gunk that’s solidified around the edges of the connector. Don’t worry about displacing the charging pins. They’re designed to move freely when you touch them.
If the pins are still stuck after multiple attempts, press them sideways with your fingertip to pop them back into place. [13] X Research source Careful and regular cleaning around the charging pins will make them less likely to stick in the future.
Turn the computer on and look for the icon indicating that it’s charging to appear. [15] X Research source If the adapter frequently comes out of place, it may be due to a bad magnetic connection. In this case, buying a new charger might be your only option.
