Hello! I just helped my friend with this issue! Ok ur computer is on hibernate/sleep mode. You must unplug your computer first and then remove battery . Leave battery out for about 30 seconds. Then put battery in wait 10 second pop out the battery again.wait 12 seconds put the battery back in and then plug your computer in . Now press the power button wait for it to turn on. Then a screen will come on stating that your computer wasnt properly shutdown. Then highlight the button that says proceed with windows program. And your computer should turn on as if nothing ever happened. Any issues please ask and ill help!!
