SOURCE: cant put songs onto my daughters bratz mp3 player

When plugging a USB removable device/storage, you should see an icon named "Safely Remove Hardware" in the system tray (right side of the task bar, near the clock). Left click on it, and you should see a list of removable hardware.
If you can not see the device there, then there is problems with your MP3 player, perhaps the battery is too weak; if this is the case, just leave it a few minutes until the device charged and initializes and recognized by the computer.
If you can see the device, but no drive letter assigned to it, then there is problem assigning drive letter to it.
You can re-arrange the drive letter assignment by entering Computer Management console: right-click on My Computer, then click on Manage.
Choose Disk Management, and assign a drive letter to your device.

SOURCE: wanting to download music onto

You have to use any available on the net converter to mp3. I suggest Format Factory (here is the link for you to download it from the official site). It's a freeware program and it could be usefull when you need to convert video files too. In two words it convert all multimedia files to all multimedia files. Of course if you'd like you can use any else you want.

In case of a problem or clarification, don't hesitate to post me a reply.
If you are satisfied, accept my solution. Please consider leaving a 4-thumbs rating; I'd appreciate it greatly.

Thanks and regards

SOURCE: I cannot get my daughter's

MP3 players can only play music files in mp3 file format. You need to convert your CDs to mp3 music files onto yourcomputer or download them from the Internet and then copy them to your MP3player.
You can do this using Windows Media player and Rip the CDs - Media Player willcreate a MP3 music file for each music track.

I bought a sylvania mp3 smpk4083 mp3 player and it orgianlly worked with my computer, but now when I connect it to my computer it turns on my player, but won't be regonized by my computer? How do

Same thing happened to me with an IPOD. When I plugged it in to one of my USB ports, it ******** up all the USB ports. I suggest reinstalling the drivers for your USB Ports. Then install the software that came with your MP3 Player before replugging it in. Good luck :)

The battery is not charging

You can try and reset the player. resetting a Clip player: 1. Slide and hold the Power switch up for approximately 20 seconds. 2. Release the Power switch. 3. To turn the player on, slide the Power switch up then release instantly.
Some things to check for when your player does not act like its taking a charge.
USB Cable 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.

My son's mp3 stopped playing yesterday. We plugged it into the computer. There's no response from the player and no indication from the computer. the usb ports on the computer work.

Are you plugging it infront or at the back USB port of the computer? Try turning it off first and then plug at the back usb port. Once plugged in, that would be the time you turn the MP3 player on. If the computer still does not detect the mp3 player as new usb device, then i guess the mp3 player must have been fried due to not being "safely removed" from the usb port. Make sure you are safely removing ALL usb devices when disconnecting them from the computer.

How do I charge my daughters amt mp3 hello kitty clip on. when I plug it into my computer do I turn the player on to charge or keep it off. she was kind enough to lose the directions.

G'Day To charge your AMT mp3 player you must first plug it into your PC USB port using the supplied cable. Next turn on the player using the sliding switch on its side.The indicator shows the battery is charging, but it is not. To make it charge you have to turn the player off. To do this, hold down the "play" button until you get the "Bye-Bye" message. The screen will go black and the battery will now charge. Do not use the slide swich to turn off!...woozie. Australia

On the intro screen it freezez and eventually goes to the next screen and says refreshing database but it dosent refresh

This seems to happen when the database gets corrupted.

1. Turn off the player.

2. Plug the usb cable to the computer, don't plug it to the player.

3. Slide the lock switch to the right, you will see an orange strip.

4. Hold the menu button to start the player. Don't release it yet. Wait until a shutdown message appears and the player goes off again.

5. Plug the usb cable to the player end. The player should go on again. The player should mount as a disk on your computer. Find this disk and back up its contents.

6. Format the player, as explained elsewhere.

7. Disconnect the usb cable. This time the database should refresh properly. Once this is done, slide the the lock switch to the left and turn off the player.

8. Turn the player back on. It should work, but you will have to load your stuff again.

9. Redo steps 1 to 5, except that now should copy your music, videos, etc, back into the player.

10. Repeat step 7.

11. Turn the player back on. It should work again.

Frozen SanDisk M240 MP3

It will turn on but freezes at the opening screen. Cannot access the menu whatsoever. I've tried plugging it into USB in the back, removing the battery, sliding the Hold button to the right as advised in forum suggestions but nothing budges it from the opening screen. Also: it does not show up as being attached to any computer I plug it into. Got a fix?
