Yep, it's called a battery pull. So even after a battery pull, when you plug it into the charger the red LED still doesn't light up? Gosh, I don't know what to think. Your phone may have committed suicide. What were you texting? Just kidding.
There is a way to force the phone to reset itself by pressing on a combination of buttons. If I'm not mistaken, if you hold down the Power + Vol Up + Vol Down at the same time you should get to a hardware menu that will allow you to factory reset the phone. I think that's the key combo, I'm not exactly sure. But, being that your phone won't even react to a Power button press, I am not sure this will work anyway.
One other thing to try is a different charger and/or USB cable. Or a different battery.
