Why won't my HTC Desie 526 turn on?

[AC Question]

I had it on the charger all night and this morning when I went to turn it on it wouldn't. Even when it's dead I can still turn it on to check the time or something. But now I can't. It can't just be dead it's been on the charger for 12 hours. I've been holding the power button since before I started this.

Try removing and replacing the battery. If no go, perhaps the battery or some other internal part has failed.
