Charger isn't working properly?

@manavkumar download the Maintenance manual for your Lenovo from here Disassemble your LEnovo and check the battery. A dead battery can't be charged. So, you may need to replace it. Also, measure the voltage on the DC in jack and see if you get the proper voltage to the motherboard.

Not sure if your 320 uses the same setup as the 320s. The 320S DC-in jack is easily replaced since it has its own cable. Once you open your bottom cover, start taking pictures and post those with your Question. that way we can see what you see and hopefully guide you further.
