Sansa i have a sansa c250 and my computer will not recongnize it will charge but not read

Three possibilities;
1) You have a dead battery because the battery is no good.
2) You have a dead battery because your Sansa is no longer charging the battery.
3) You have a dead battery because you didn't leave your Sansa tethered long enough to charge it up.

When you have the Sansa c250 tethered to the computer, you should see a tiny yellow lightning bolt flashing, and a battery icon that shows the amount of charge on the battery.

If you see the lightning bolt, but the battery does not charge after being tethered to a working computer or charger for 24 hours, you may need a new battery. You can get one on Amazon.com. Here's a link:

If you see the lightning bolt, and the battery charges after 24 hours, AND your player works when unplugged--Problem solved! You just need to let it charge for a longer time.

If you do not see the lightning bolt when the player is tethered, and the battery indicator shows "empty," It's likely that the internal plug to your Sansa c250 has broken. Your Sansa is no longer able to charge the battery.

If you happen to be an electrical engineer, or otherwise have a shop full of electronics equipment (including signal injector, volt-ohm meter, needle-tip soldering iron, and stereo magnifying goggles with work lamps) you may be able to fix it yourself. Otherwise, forget it-- your Sansa is dead.

If it's still under warranty, try to get it replaced. Failing that, it's time to get a new MP3 player.

Hope that helps! Please post a message to let others know what happened to your Sansa player.

It takes a while. Try leaving it charged over night, then tell me if you have any problems.

i herd this worked for sansa players. if u right click the player in my computer on a pc than chose propertys it will show batter charge.

I had a similar problem. My Sansa c250 would charge, when plugged into the computer. It would read that it was writing but the computer did not recognized that the Sansa c250 was connected. I switched to a different USB port and got the same results. I then realized that the two ports I was using were 1.0 port and idmedeatly when inserted in the 2.0 port it began charging and the computer recongized the Sansa c250. I know this won't solve every charging problem one may have. Changing the battery would be easier in some cases. Especially if they were sold like the AA or AAA.

yes just buy a wall plug in charger

What op system are you running?

I have the same problems and did the same things you did until I update the Windows Media Player to 10. It works fine now.

turn on the lock button and hold the record button and plug it in computer while you hold the button . easy as that hope it works for ya!!!!!!!!!!!!!!!!!!it worked for me i think it will workfor you

Get a USB cord and connect it to the computer. It will automatically charge with no software installed on your computer.

My Sansa only reads mp3 or WMA files, not mp4 files.
also, i have tried three different computers, and all of them recognize (or NOT) my player differently....
