have you replaced battery?
1. charger is not working
2. battery is bad.

you DON'T charge the camcorder with the usb cord,you only move files between cam and computer,you need a power cord that plugs into the wall,see pic, LETO 2A AC Power Charger Adapter USB Cord For Panasonic HC V100 HC V500 HC...
ihave the same camcorder,

If you last charged it with the computer USB port, try charging with the supplied AC adapter instead. If you last charged with the computer USB port, try charging with the AC adapter this time. This will help isolate a bad AC adapter / power cord or USB cable / USB port.

It is important to note that if you are charging your Kindle via USB port on a computer, when many computer enters "sleep mode" the USB power is shut off at this time too. Charging is effectively halted - even though still connected. You should only expect to charge while the computer is active or when using the AC adapter.

You can also purchase an aftermarket DC charger. These are small plugs that are inserted into your auto's port or cigar lighter. They provide 1 or 2 USB connectors to plug in a USB cable. These devices are suitable to supply / charge just about any devices that uses a computer's USB port to power / charge a device. They cost anywhere from $5 and up and look something like this:

I hope this helps and good luck!

Yes, you can charge the battery by connecting the camera to a powered USB port. Be aware that not all computer USB ports put out enough current to charge batteries, and you want to connect it directly, not through a hub. Alternatively you can use a USB charger that plugs into a wall outlet; such devices are available for cell phones.

Yes, you can charge the 8025 through the USB port, assuming the computer puts out enough current to do so (not all USB ports do). Or you can take the battery out of the camera, put it into the charger, and plug the charger into a wall outlet.

Make sure that the USB cable is properly plugged in and use the original cable that came with your player.

Computer in Hibernation mode
Make sure the computer isn't entering hibernation or sleep mode while the device is connected. The computer must be ON in order to charge your player.

USB Port 2.0
Make sure the player is connected to a USB 2.0 port (1.1 occasionally causes charging problems).

USB Port location
Try plugging into different USB ports (i.e. USB port in the back of the computer); occasionally the front USB ports have limited power to charge up the device.

Battery
Make sure the battery is fully charged. It takes approximately 3 hours to fully charge the battery.

Latest firmware
Depending on what Sansa player you have, make sure it's up to date with the latest Firmware.

AC charger (optional)
AC chargers (sold separately) have a 500-1000 milliamp max output, which provides much better charging ability than a USB port. These accessories are available at SanDisk web site.

You can charge the battery in two ways.

Use the supplied battery charger. Remove the battery from the camera, put it into the charger, and plug the charger into a power outlet.

Connect the camera via a USB cord to a powered USB outlet. Be aware that not all computer USB ports put out enough current to charge the battery. You might want to consider a cell phone charger that plugs into a power outlet.

From page 7 of the manual, you have two choices.

You can charge the battery with the USB cable, connecting the camera to a computer. Bear in mind that not all USB ports put out enough current to charge a battery.

You can use the supplied battery charger. Put the battery in the charger and plug the charger into a wall outlet.

Start with another battery. Borrow a friends or they are available on Ebay rather cheap. Or, go to your Cell Carrier and ask them to help you try another battery.

Have you tried charging it through the USB port of you computer? The phone is designed to charge from a USB port also, but computer must have ActiveSyn phone driver install and be recoginzed by the computer in order to charge using USB port.
