Apologies that your computer is not working as expected.
Since you haven't included your computer's model number or operating system, I can only give a general answer to your question.
From what you're describing, it sounds like the battery may have reached it's end of life. Have you tried it with a different battery? If that's not the issue, then the charger may be bad, have you tried a known working charger? If the charger and battery are good, then the charging circuit on the motherboard may be at fault. If that's the case, then the motherboard would have to be replaced.
