While you're plugged in to the charger, go to settings-options-status. You should see a battery % line telling you how much the battery is charged up. If the battery is old, it won't be able to reach 100%. Try a power cycle and check again.
All that happens is the screen turns blank white, then dims, then goes off and repeats the cycle. I get no battery icons or anything. I have tried both a wall charger and data cable charging, both with the same results.
