Vostro 15 3510 needs to be plugged-in to turn on

Hi, I just bought the laptop and to turn it on it needs to be plugged to the power source, but after booting I can disconnect the cable and the battery seems to be working fine. Other than that the computer is running as intended. I am using Ubuntu 20.04.4 LTS and already tried updating to the most recent BIOS. Drivers are also up to date.
