I am traveling to italy. My sony dvd 101 handycam

hi if you have the charger plugged in the camera the you have power to work it, if you unplug the charger and it dose not work, the I think the battery is not charged fully or it is no good after being left to long, check to see if the battery is charged. I hope this helps you, please let me know.

non replacable builty in rechargable

Sometimes the batteries will build up a memory if they are only used for short periods of time and never used to the point of going completely dead, so possibly getting a new battery online. B&H photo is a pretty good site.
I know some chargers have an output to the cameras battery connector that powers the camera, and if that is plugged into the charger it will not charge the battery simultaneously.
If the camera is working when plugged into the power source it usually turns out to be a battery problem. Sadly the only choice it to buy a new battery.

the battery charger is maybe defective already you can purchase new charger from dealer

I recently purchased the same exact charger for the same exact battery....I had to slide the battery in backwards to align the positive and negative and then it should charge properly. If you slide it in the other way which seems to be the front side of the battery the light will automatically appear green same as if no battery was in the charger. This is because its not aligned to the positive and negative from the battery to the charger. Best Wishes!

Some camcorders have only an external battery charger. You may need to purchase an aftermarket charger for your camera or a dedicated charger from your local Sony dealer.

the batteries!

Hi,
Battery charger might defective, please check it and if requires new one click Sony to see its price and stock.

Is the charger plugged into mains? If so, check that all the connectors are firmly attached, if you still have a problem, it may be your AC adaptor.

This camera has had problems with the primary switch block faulting. The camera will power up all by itself when unattended and drain the battery. Another symptom would be the battery refuses to charge fully because the camera must remain in the "OFF" mode for the charge process to begin. Sony in Laredo, TX is replacing these controls at little or no cost, I would call them to see if they will repair this for you. Hope this helps you.
