What does the button do?

The button is a hard reset incase the laptop ever falls into a lock state that requires removing the battery to recover.

Why is your battery misbehaving?

There are several possible explanation:

• Battery not calibrated

New Lithium Ion batteries do not achieve their full capacity until they have been exercised. Apple recommends that you fully drain and charge the battery 3 times.

Samsung has a document on calibrating laptops

• Bad Battery

It sounds like your battery may be defective from the manufacture. It should still be under warranty.

• Bad Charger

Try turning off your laptop, and see if the battery charges. Your charger will still be under warranty.

Unless the battery isn't calibrated, all your other options would involve returning it to the store.
