Does the power adapter have an LED on it so you can tell when its plugged in? If so, does it stay lit? I had the power adapter for an external drive go bad on me, and it sounds like what you're experiencing. The power supply would be on for a couple seconds, then off. Then on, then off. Every couple of seconds. If that's true in your case, it may be forcing the Pismo to use the battery. If the power supply doesn't have an LED, you may be able to hear it kicking on and off if you hold the brick part close to your ear. -Mike
