Recharging mp3 I thought plugging my mp3 into the usb port would charge it, but it isnt getting a charge and i lost my manual, is that the right way or is there another way to charge it?

From what I can gather, the recorder has an extendable USB plug that slides right out of the recorder. You use that to plug your recorder directly in to a USB port on your computer. According to the directions in the manual, make sure the recorder is in stop mode first then plug it in to your computer's USB port, then press ok on the recorder when promted to start charging. Here is link to the online owner's manual that goes through the details on how to charge the recorder.

MP3 players are charges with the USB cable. Connect the cable to your player and then plug it into the USB port in your computer. While it is charging you can download mp3 music files to your player.

Have you tried a different cable?
Does the USB port on your computer power other USB devices?
The manual says to plug it into USB, make sure your computer is switched on and leave it for at least 3 hours. No other requirements.
Try leaving it on charge overnight. Has it been left umcharged for a while?
One final thought that has caught me out. Are the plugs pushed fully in?

A dead battery is a possibility, how long have you had it, and has the pattery lasting the full expected time?

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.

Battery

®
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

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

3. The computer must be on for most USB ports to charge your battery. Your
Sansa

The battery level indicator will blink while charging. You will not be able to

Make sure the hold/lock is not engaged- it will prevent the player from charging.

if your mp3 player comes with a usb charge cord and has no bulge in the cord, such as would contain some kind of voltage modification electronics, then it's ok.
   the reason is: both the motorola charger and the usb port are  5 volts, all usb is 5 volts standard, and the motorola charger is labeled 5 volts right on the unit itself.
    The the only possible problem would be if the motorola charger was wired differently. However I have been using my razor charger to charge my Emerson 2GB mp3 player w/no problem.
    Plug in the charger with the mp3 player powered up, you should see the battery icon filling up just as if you were using the usb charger.
    if you are still to worried to try it , then get a voltage meter and test the polarity (weather positive and negative are the same on the motorola charger as the usb cord when plugged into the computer.

check to see if you can charge it via another unit like a pc or a usb wall charger, if it does than your ports are getting loose from use or going bad call Sony if thats the case, its 18003457669. good luck!

Try a different usb port on computer (make sure the usb ports are 2.0). If still nothing, do the 5 r's suggested in the user's manual - if you lost the manual, you can get it from Apple's website.

If there is no removable battery (implying it has a internal rechargeable battery) then the device will charge from the USB port.

Please note : Some USB ports will not charge your device if its power requirement is too high! (EG. like ones found on the back computer keyboards)

Try the usb ports directly on the workstation.

Please don't forget to rate!
