Hello and thank you for your question. I look forward to assisting you today. I am a little confused when you state you were using it without the adapter to charge the battery? If the battery was drained, it will take several hours for it to charge. Try removing the battery and use the power adapter only. When or if you see the menu with the option to Troubleshoot, select that and follow the screen prompts.
The battery won't charge without the charger plugged in, that was my question. You stated above you were using it without the adapter to charge the battery? I couldn't quite figure out how you were doing that without an AC power source?
