My screen was frozen and no power lights turned on; I tried everything posted here, including calling Amazon, who said it looked like my screen was done for after we tried everything again for good measure. I opened the back and messed around a little, taking the battery out and putting it back in, and just pushing on connections to make sure they were snug. Now I just plugged it in again and the amber charging light is on! Progress...I never found the reset button, though. I think I have a first generation kindle keyboard. I bought it secondhand on Amazon.
