Methods and sites I've used to solve this...

Refer to the following....

A. Reset the SMC and your NVRAM:

(Applies yo Intel-Based Macs Only) Sometimes when changes are made to the system(i.e. Updates), system configurations (i.e. for Power) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take sometime, being certain you have the time to perform these resets.

B. Try a New Charger:

• Power & Cables - Mac Accessories - Apple - Select "Mac Compatibility" on the left
• Find the Right Power Adapter and Cable for your Mac Notebook - Apple Support
