Lenovo Ideapad: Battery plugged in, not charging?

The battery is built-in and not easily removed, so I didn't disconnect it. But I did uninstall the battery drivers in the Device Manager and rebooted. I did check the Lenovo battery settings and "Conservation Mode" is "Off". I've tried everything. It did this yesterday and - for no apparent reason - started charging again. Now, it's back to "Battery plugged in, not charging". It's a new laptop I've had for less than a week. What's going on and what can I do to fix this?

Some Lenovo Thinkpads have a mode to extend battery life before replacement that holds charge to about 70%.
That would explain the issue.
It's within battery setup.
Removing the battery drivers can badly muck-up some laptops including Lenovo.

You take it back now right now you only get 10 days in most stores ti return it then its good luck getting the factory to help you
