Swapping cables is the most effective way to determine if the problem lies with the power adapter or the machine. It is frustrating when a MacBook Pro charger not working disrupts your workflow or disconnects you from critical tasks.
Follow Apple's Diagnostic Steps for a MacBook Pro Charger Not Working
Using a flashlight and a soft-bristle brush, you can often dislodge the debris responsible for the intermittent connection. Dust and lint accumulate inside the port over time, creating a barrier that prevents the prongs of the charger from making proper contact.
Updating the operating system to the latest version can resolve these communication errors, as Apple frequently releases patches for power management bugs. Furthermore, navigating to "Battery Health" in System Settings provides insight into the maximum capacity and whether the software is misreporting the battery status.

If the charger is old, showing visible wear, or fails to provide a consistent charge, investing in a genuine or MFi-certified replacement is the most reliable path to restoring full functionality.
