Dell Latitude "plugged in, not charging" and blinking orange battery symbol on Windows 10

I have a Dell Latitude that was working fine until recently when all of a sudden the battery light started blinking orange and the battery would no longer charge. It says it's "plugged in, not charging"  and I've tried to shut down-disconnect the adapter-remove battery-reconnect the charger-turn on-uninstall the Microsoft ACPI-Compliant Control Method Battery-shut down-insert battery-turn on, but nothing has worked so far. Also, when I turn on the laptop, it turns on and off a couple of times before starting fully.

I tried to use a different battery, which shows a white light but still doesn't charge. Not sure what happened since it was working fine before.
