How to charging in my ansa C240 MP3 player? - SanDisk Sansa c240 MP3 Player

This is normal when the Sansa is connected to a computer. You can use it while charging if you connect it to something else. For example, you might have a cell phone with a USB charger that plugs into a wall outlet. You could connect the Sansa to it, and it would let you listen while charging.

is that mp3 player have the facility to add memmory card... then see in the side of the player their will an space given to insert that mcardf

Try connecting directly to USB port on your computer, NOT a hub. It needs power to charge.

On Windows XP, when you open My Computer, the Sansa C240 shows up at the bottom, under "Other". Because of DRM restrictions, you cannot copy media files to the C240 using Windows Explorer. You have to use Windows Media Player to sync playlists to the C240 (WinAmp can do it also).
I also suggest that you check out RockBox. It's an alternative operating system for portable media players and they have a version for the Sansa C240. It will give you some additional functionality.
As far as I can tell, to copy files to the microSD card (if you're using one) you have to use a media card reader, then insert the card into the C240.

Make sure you plugged into a usb port on the computer, NOT the hub. It needs the power.

There is quite possibly a problem with the USB cable or the USB port on the computer, but try this shortcut force to force the computer to recognize the Mp3 player: Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard

The songs are in the wrong format - read my 2-part article on song formats under my profile for more detailed info

short answer: convert the songs to Mp3 format, and you will have no problems

most sansa players will; not charge on a laptop. plug it into a desktop

Does it indicate that it is fully charged? If it does, I would return it or have it replaced. You have a 1 year warranty from SanDisk. SanDisk Technical Support 1-866-726-3475 If not, try using a different USB port on the computer, preferably one in the back. Best of Luck.
