I keep reading where everyone is saying the Charge indicator light.... I have a Sony PRS 505, and I don't see a charge light anywhere. Where is it supposed to be? I bought a wall charger for it, because it won't reset with a hard reset, and have had it plugged in for 3 days. I have no idea if it is charged, since I can't find that supposed light. I try to turn it on, and nothing happens.... I bought a charger on ebay, the is specifically for the Sony PRS 505, so I know it should work. I still can't find the "charge light" though. A little help?
