battery not supported

I’m facing an issue with my Dell Latitude 5591 laptop. Recently, the battery backup suddenly dropped to 0%, and the battery stopped charging altogether. Initially, I thought the problem was with the charger, so I replaced it, but the issue remained. I then replaced the battery, but the problem still persists.

I generated a battery report, which shows that Connected Standby: "Not Supported", and the laptop still isn’t charging. Could you please help me troubleshoot and find a solution to this problem?
