Sony DCR-VX2100 will Not Power on By Battery Unitl I connect AC power adapter. I connect the battery to the camera, turn it on and nothing happens as if the battery is dead, even though it's fully charged. If I then connect the AC adapter the camera works fine, and will run off the battery if I disconnect the AC. Then I can pretty much use the camera all day, once I store the camera for a few days and connect the battery, I again have to connect the AC to get the camera going. Thoughts?

Try this:

1. Turn off the Handycam
2. Remove the battery from the Handycam.
3. Remove the AC Power Adapter from the Handycam.
4. Move the Handycam power switch to the ON position.
Note: Leave the switch in the ON position for at least 15 seconds.
5. Move the Handycam power switch to the OFF position.
6. Connect the AC Power Adapter to the Handycam.
7. Turn on the Handycam.

Good luck!

According to Sony, the 31 problem is one that requires a power reset of the camera. Turn off the camera, remove the battery, remove the AC adapter if it is in use and then wait several minutes before re-attaching the battery and/or power and turning the camera on again.
The 23 problem is a non-Sony InfoLithium battery. Apparently these smart batteries interact with the camera. According to Sony: "Replace the battery in the camcorder with a Sony® InfoLithium battery or connect the supplied AC power adapter."
