iPAQ won't turn on
I pushed the power button and there are not any lights anywhere

First things first. Try pushing that ON button one more time. If you are not sure where that is located, it is above the screen on the front face between the two LED lights.
Dead/Bad Battery
If your iPAQ hasn't been used in a while it is very possible that the battery has just run out of juice. Try plugging in the AC adapter or the USB cradle. It might not turn on, but you will see lights if it is charging. If there is still no response you probably have a bad battery. See the guide here to learn how to replace the old one.
Broken/Stuck Power Button

Stuck Power button
