Yesterday I tried to turn on my laptop but it couldn't turn. I plugged AC adapter and tried and its turned on. I realized that my battery is identified but Its not charging. When I disconnected power adapter, It completely cut the power to the laptop and Its shuts down completely. Also when I restarting It, My keyboard back light lightning with its default settings. I saw 2 questions on the community but I didn't even tried to disassemble my laptop for any purpose. 
I tried to,
  -press my power button for 30secs
  -uninstall drivers from device manager
  -pressing battery reset button for 5secs.
anything didn't went well. 
I appreciate if anyone can help.
Thanks if you can help !
