With an extensive use of the notebook,
some times notebook would store some static charges which
indeed will stop the notebook from powering up or charging
the battery. The procedure to remove this static charges from
the notebook is known as power drain. Performing a power
drain procedure will not effect any personal data or delete
any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these
steps:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.
