I. Reset the SMC and your NVRAM:

What it could be is the power management settings. Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Power and for Ports) become manipulated, technically. So, reset the SMC and NVRAM. Your power adapter may not be being seen promptly by the ports, or your battery may not be charging affectively. By reseting these, all of the ports would be configured to how they should be.

II. Perform this Thrice:

Note that you may need to perform each thrice. This can be time consuming, to be certain you have the time to do so.
