Charger polarity inverted by mistake
By mistake tha cable charger polarity was inverted and the notebook is no more charging.
Not sure if your charger is the type that shuts itself off, when something is wrong.
Does the charger have a status light ? Does it come on when you plug it into the wall ?
If not, the charger may be dead.
In any case, remove the laptop battery. Do not leave it in the machine.
If its over 2 years old, I recommend a replacement.
Try- With the battery out, plug in your charger. Will the laptop power-up ? Are any lights ON ?
The charger (assuming it still works) will power the laptop without the battery. Usually, the battery light will show red/yellow/green. PowerOn/Charging/BatteryGood/Bad
If it works, you're happy, all you need is a new battery.
If it does not work, take laptop, dead battery, and charger to the serviceman. There are several tests that can be done without dis-assembly. Before you D.I.Y. ( Do It Yourself ), search the web for "samsung laptop how to". You will find several YouTube movies.
