Contact Samsung CC , they will help you out.. these are known issues and they will let you know the correct technique to fix the issue.

Check with other power points, if possible check with an alternate power supply cord?

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?

The whole thing is brand new i just bought laptop yesterday.

^^Contact the retailer/dealer then.Dont compromise with new Product.

Exactly. If its brand new there can be no compromises whatsoever. Get it replaced. Try not to settle for anything less. :wink:

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.
