Wont charge when pluged into usb port

Have you tried replacing the battery?? If its an older phone, the battery may not take a charge anymore.

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.

The player has a built in rechargeable battery that can charge by pluging it into a usb port on your computer or into a usb wall charger. if you have a mac i should warn you it will only let you charge nothing else.

If it will turn on a little, tap the icon for the battery in the upper right hand corner of your main screen. This will bring up a "system status" screen. Tap the icon of the battery there also. It will then pull up a tabbed screen. Under the "battery" tab, make sure that the check box next to "when device is turned on, do not charge the battery when connecting to the PC" is UNCHECKED. Then try plugging it into a USB port and see if it will charge or sync. I hope this helps!

Battery
The Sansa
®
Clip player comes with an internal rechargeable battery. To use the player for
the very first time, remember to fully charge the battery. You can charge your Sansa
®
player through the USB port of your computer, a car adapter (not included) USB port, or AC
adapter (not included) USB port.
Charging
To charge the battery, please follow these steps:
1. Connect the larger end of the USB cable into an available USB port on the
computer.
2. Connect the smaller end of the USB cable into the Sansa
®
Clip player.
3. The computer must be on for most USB ports to charge your battery. Your
Sansa
®
will show connected and the yellow charging indicator will appear.
The battery level indicator will blink while charging. You will not be able to
play while connected to the computer USB.
4. To stop recharging, simply disconnect the cable.
The battery can also be charged using an AC adapter (not included) or a car adapter
(not included) and you will be able to play your device while charging with one of the
adapters.
NOTE: Some low-power USB ports may not be able to provide enough charge
power. Also note that the rechargeable batteries are not replaceable.

I think the charger is the problem. I ordered one of these and then it wasn't charging the day I got it....it's supposed to go from red, to orange to green as it charges, but the red LED just goes off after a while, before the headset is fully charged. I solved this by charging it through a USB-to-miniUSB cable on my laptop USB port. This worked beautifully....unfortunately I think the H700 chargers are faulty.

dude sounds like u need a vipower usb 2.0 4-port hub

My question would be, what are you using to charge it? The USB cable or the wall adapter? In any regard I had a similar issue with my 6800 and the solution, use the charge base to charge just your battery, or figure out if there is some debris in the charge port. My personal solution was to just clean out the port and get rid of pocket lint and other debris, but until I figured out that that could have been the problem, I just used the base. Hope that helped.

have u trided pluging it in to your computer thats how i charge my zen
