Why Does My Charging Cable Stop Working. The Apple power adapter the plug bit and the Lightning to USB cable or 30-pin cable if youve. The debris is building up at the base of the port and the problem comes when theres enough that the cable is kept from going all the way.

If that does not happen and you find the laptop not charger even after plugging in the charger then there could be several factors behind such a problem.
