Sansa mp3 player

The very first time you charge your battery YOU MUST CHARGE IT FULLY!!! If you didn't, that is probably the problem.

Also, even if you charge the player for just a couple of minutes it will APPEAR to have a fully charged battery when it actually doesn't.

Most portable media devices require at least 20 minutes to an hour to fully charge whether the screen shows that it is fully charged or not.

Hi
Check the Manual
User’s Guide


Hay Don't worry it will work
Note: Some low-power USB ports may not be able to provide enough
charge power. Also note that rechargeable batteries may
eventually need to be replaced as they have limited charge
cycles (which vary with use and settings).

Li-ion Battery
The Sansa e200 MP3 player comes with a replaceable and rechargeable
lithium ion battery. To use the player for the very first time, remember to
fully charge the Li-ion battery. You can charge your Sansa through the USB
port of your computer, a car adapter (not included) USB port, or AC adapter
(not included) USB port.


Please execute the following instructions for charging the battery using
an USB port.
1) Connect the smaller end of the USB cable into an available USB
port on the computer
2) Connect the larger end of the USB cable into the dock connector of
the 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, 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. The battery will reach
approximately 70% charge in 2.5 hours and full charge in about 3.5
hours. It is recommended that you fully charge your Sansa e200
before the first use.

I have over 10 years experience in electronic tech support.

How long is the charge lasting? If you're only getting half of the battery life you use to get, then the unit needs to be repaired. I can do more research into your model, but normally there isn't a way to change the battery charge display. Please let me know if you're still getting full battery life even though the display is only showing half.

I'll use the information you provide to assist you further. I look forward to hearing from you.

I found this online at www.sandisk.com under warranty and manuals link.
I believe they have an excellent Return Authorization system, that if you truly have trouble with your disk player and it's still under warranty, gather your receipts and get on line to get an RMA. I have successfully returned to disc players that were infact faulty (FAT problems) and received two replacement players. Get on it right away. Look at the manaul online too. IT can be very helpful. I've included the Battery info, and the link for the manual at the end.

This is direct from the sansa FAQs at http://www.sansa.com/support/sansa_clip/faqs 02. Why won’t my Sansa Clip charge when I connect it to my computer? USB Cable
Make sure that the USB cable is properly plugged in and use the original cable.

Computer in Hibernation mode
Make sure that the computer isn’t entering hibernate 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 your player is connected USB 2.0 port (1.1 occasionally causes charging problems).

USB Port location
Try plugging in different USB port (i.e. USB port in the back of the computer); sometimes the front USB ports have problem charging up the device.

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

Latest firmware
Make sure to update firmware by downloading and installing the Sansa Firmware Updater.
