Lenovo ideapad 100s does not start

Hello, The battery was low and turned off before I plug the charger. Then I tried to turn on the computer while charging, but it doesn't turn on. Both indicator lights for power and for battery charging are turned on. But the computer doesn't start. no fan and no screen functioning.
To take out the battery, I need to screw all the body cover at the back. I need a solution if possible with out opening the back cover
thank you
