Battery could be dying. Do you often leave it plugged in while using it?

MERGED QUESTION
Question from chauhan049 : "asus notebook runs only on power source"

My Li-ion laptop battery indicates "plugged in, charging" but the percentage is just 0. Without a power source, the laptop turns off. What can I do?

Stupid guess... dead battery?
