Hi,
That means that you charger doesn't produce enough power to the machine, look at your wattage and the current output on you charger and compare it to the input of your laptop, if it marches, then try using the same charger on your friend's laptop, the u will know whether u need to buy a new one or just bare the pain of borrowing.
All the best

Cheers
