My Lenovo Thinkpad T480 Laptop getting warning message "PC isnt charging, use correct USB C charger"

Hi,

My Lenovo Thinkpad T480 Laptop getting warning message notification with sound that "PC isnt charging, use correct USB C charger". This is constant every 5 secs after the battery is fully charged.

I am using Windows 10.

My battery is charging and discharging. But the message is annoying. 

My Battery 1 and 2 both gets charged to 100%

Then the message starts appearing. I normally use my Laptop with charger plugged in.

 

Please help...
