Plug the USB cable they provided to a PC and hook the other end to the mp3 player. It takes about 4 hours to fully charge.

this happened to me wen i first got mine, so what in the manual the mp3 will need at 4 hours at first to be charged fully, when u charge it flip the on/off switch ON, n let it sit as long as you can. thats the only way it will charge, the reason why it keeps turning off is becuz its on low battery

Make sure the player is fully charged. 1. Connect the player to the PC. 2. Make sure the computer detects the player.
NOTE: If needed, switch the player to MSC mode, 1. Turn device OFF. 2. Slide the Hold switch down to Lock (orange color showing). 3. Press and hold the center button while connecting the device to the PC.then connect it to the PC. Next Be sure the battery is charged 1. Leave the player connected for approximately 2 hours to charge. 2. Disconnect the player from the PC. 3. Verify if you can turn on the player. 4. Reset the player if necessary. To reset the player: 1. Press and hold the Power/Menu button for approximately 20 seconds. 2. Release the Power/Menu button. 3. Press the Power/Menu button again to turn on the player.
If that does not do it, re-seat the battery: Here is how to get to the battery, 1. Press the battery compartment in while sliding to the right. 2. Remove old battery. 3. Insert new battery or reset the old battery. 4. Close the battery compartment. Then try and see if it will come on with out the battery hooked to your computer. 1. Remove the battery. 2. Connect the player to the PC to verify if it turns on. 3. Re-seat the battery to ensure proper connection. 4. Verify if the player turns on.

(1) Hit the reset button for 5 seconds.
(2) Hit the reset button, slide down the on/off slide, and have it plugged into the computer at the same time. Hold for 5 seconds.
(3) Hit the reset button again.
(4) Charge it for at least 10 hours in the port in the BACK of your computer.
(5) After 10 hours, unplug the player and press the + volume button. While still holding it, plug the player back in. Keep holding it for 5-50 seconds. (most likely nothing will pop up).
(6) Let the player sit UNPLUGGED for a good 3 hours.
(7) Plug the player back in (it should light up now). Let it charge the usual time it takes to charge for an empty battery, about 6 hours.

Your battery is recharged when connected to your computer. Turn the player off and connect it to your computer via the USB cord. The computer must be turned on. Initial charge should be for 10 hours with subsequent charges 3 to 4 hours for a full charge. A quick charge of 1-1/2 hours will give you a 70 percent charge. A fully charged battery will last up to 15 hours under normal use.

usually, when you connect the USB to the computer, it will begin charging right then and there.  can you please be more specific?

if you have any (car or home) mini usb charger it will charge it for a few seconds but do this multiple times until if at least turns on then charge it from your computer

My friend give me a sansa mp3 player BB0703UBB. When i charge it in my PC and i forgot to unplug sansa mp3 player BB0703UBB after half hour i plug it. But the power is not working. i cannot open and play it anymore. I try to insert it on my PC but then it says unknown device. HELP!

Uhm.. Do you plug it up to your computer to charge? Mine is old and dies after about two hours.. I know I need to replace. But in it's old age I guess (Bought from ebay) it won't charge connect to my computer.. So, maybe if you haven't tried already, to try that. Though, sounds like it's getting old like mine and will need a new battery soon.

Check the battery connection(s) in the back. Remove the 4 screws, remove the battery an re-connect it. Charge the device for a few hours. Best of Luck.
