Disconnected? It's not absolutely necessary to disconnect the battery, but it is good practice. If you have a Lenovo laptop, there's an option in the BIOS that cuts all power from the battery without needing to physically remove the connector.
As a possible fix, with your laptop turned off, unplug the charging cable from the laptop and then remove the battery from the laptop and leave it out for at least 5 minutes. During this time, open your laptop and press and hold the power button for 10 seconds. This will eliminate any remaining charge held by your laptops components.

Most likely, your battery has reached the end of its useful life and has stopped holding a charge.
