Perhaps try startup with 'SMC' instructions, to test..
..&/or also try 'NVRAM or PRAM' reset instructions.
Depending on vintage and technologies involved
there are different instructions based on model.

Could also be the portable's battery may have failed.
Nothing mentioned about that here; a usual suspect.
Test with different spare AC-power adapter, clean the
magsafe ports; check 'spring connectors' in plug/port?
