The dock has a seperate battery bay to charge an extra battery. What happens when you stick it in there? I had a completely drained battery and it did not seem to want to charge via USB (though the phone did turn on normally and all) some USB ports do not provide enough juice. OR you wall charger is hosed. try your computer USB port into the charger not the phone. Stick the battery in the slot. Your USB port may not have enough power to BOTH charge the battery and power the phone but should be enough to just charge the battery.
