That happens when the battery is having issues or when you are using a non-compatible charger.

How are you sure that the battery and charger are working?
Is it your own charger or borrowed from a friend?

maybe its a safety feature built into the laptop to extend battery life (& backup). if you charge fully and then drain it, its called a battery cycle. so charge till 80 & keep using till it reaches 15% and charge again.

this was what i saw in a friend's Lenovo laptop recently.
