You need to turn it off. Remove the power chord. Remove the battery. Let it sit until it turns off. That should only take a second or two once the battery is removed. If it is an Apple machine which does not have a removable battery, it could take hours to run out of power. Once it is off Put the battery back in. Plug in to power. Turn on. Report back here, tell us what happened.
