There is a switch contact that connects the battery when you unplug the AC adapter. These commonly get sprung and cease to make contact leaving the battery disconnected when adapter is unplugged, resulting in no power. Verify the battery is being connected and see if the unit works properly. If so the adapter is either the wrong one or defective.
In other words, there may be two problems.
