My synocaddie V100 does not hold a charge anymore,it works when connected to computer or electric a supply, when disconnect battery only lasts about 10 min. Manual says battery cannot be removed.

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,

Replace your battery to solve this trouble.

Get a battery from a FixYa.com advertiser or anywhere computer batteries are sold.

Thanks for your question @ FixYa.com

Does the computer start anyway, but it's just that the battery won't charge? If that's the case, it's probably a bad battery.

A procedure to do before assuming a bad battery is to (1) remove the battery, (2) disconnect the power supply from the computer, and (3) press and hold the power button for about 30 seconds. This resets the logic circuits in the internal power handling section. If that doesn't help either, then the battery is probably bad.

If the computer isn't starting, however, it could be that the power supply has failed. Check the voltage output on the power supply.

Hope that's helpful.

There is an easy fix solution that works most times when your PC/Laptop suddenly does not turn on. Dont ask why or how but follow it.
1. Disconnect all the power supply, that is remove the adapter cable and remove the battery.
2. Press and Hold the power button for 10 to 20 Seconds(very important 10 secs at least)
3. Put back the battery and connect the power adapter and try switching on your laptop.

How old is your camera already? Electronic gadgets powered by lithium ion batteries dies over time. if you had your camera and battery for over quite some time now say like a year or so, maybe the cells were drained dead and uncapable of holding electrical charge anymore. If that is the case you might consider replacing your camera battery with a fresh one.

How old is the battery? If the battery is refurbished or old it might just not charge anymore.

Also, do you have a separate charger for the battery? Many cameras do and that is how they charge, not when the battery is still in the camera.

does your battery have one of those charge indicator panels on bottom?

also, it's possible that the connection from battery to the internals is shot..if that's the case, then you're looking at a major motherboard swap

Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

My MuVo was having problems until I installed the latest firmware. The last firmware release was in July 2007. If you haven't updated the player's firmware since then, try downloading it and installing Creative MuVo V100 Firmware 1.05.01.

If you can't get your computer to even recognize the player anymore, you could try reinstalling the Creative Mass Storage Driver 1.07.00.250.
