My MP3 freezes.

1

Check the orange "Hold" switch on the left side of the Sansa C150, if you cannot turn on the MP3 player or if none of the buttons is working. When the "Hold" switch is up, the buttons are disabled. Slide the "Hold" switch down to activate the buttons again.
2

Press and hold the "Power" button until the LCD screen lights up when turning on the MP3 player. Pressing the button quickly does not turn on the device. The "Power" button is located on the front of the device, under all the other control buttons.
3

Replace the AAA battery, if you cannot power on your MP3 player. To replace the battery, remove the battery cover from the back of the device by pressing in on its tab and pulling it off. Remove the old battery, insert the new battery and replace the cover. One AAA battery provides approximately 15 hours of power for your Sansa C150.
4

Change the backlight settings to conserve battery life. This is useful if you find the battery loses power quickly during normal use of your Sansa C150. To change the backlight settings, choose "Settings" to bring up the "Settings" menu. Select "Display," "Backlight" and then a shorter backlight time. The backlight will shut off after a period of inactivity that matches your backlight setting.
5

Review your music purchases to understand what rights you've purchased to the content, if you are unable to play a track back on your Sansa C150. When you purchase music, it comes with certain rules for how you can store and play it. You may not have paid for the right to transfer the song to a portable media player.
6

Reset the Sansa C150 if it acts erratically or if you have other problems. To reset the device, open the "Settings" menu and choose "Reset All." Choose "Save" to finish restoring the MP3 player to its factory default settings. If you decide not to reset the device during this process, select "Cancel" instead of "Save."

Hi there,

You need to reset your player to default settings...
There is a reset method - check your user manual, or follow the below link -

Good Luck!!

Thanks

Wait till it runs out of power then charge it. It should charge up normally.

Just go connect it to your pc.then go to my computer and then right click on the drive which belongs to your sandisk sansa c150(1gb) 2gb mp3 player and select the option format.
Thats all.

IF it displays the logo, it seems to be a very common problem with this player.

I spent hours last night trying to solve this same issue.
Becuase the problem is SO common, and the information is so scattered, I decided to write up my discoveries on a wiki

Hope this helps!

my mp3 player don't work properly..
when i plug mp3 players in my pc it work properly... after that when i unplug it my mp3 player doesnot work upto now.
when i switch on that it will display only scandisk logo.. then that it will not work.
then to switch off that i should take out battery.. you have any solution..
after that the pc also don't detect that player

if your player is frozen, try the steps outlined here

It could be your firmware. Try updating/upgrading the firmware with the firmware updater from www.sandisk.com

This has worked for me. Good luck! (and come back and let us know if it worked!)

See my problem posting and do not be frightened.

Try connecting it to the computer without the battery. If it shows up, format it. My Computer>Sansa c150>Right click and select format. If that doesnt work, you will need to call Technical Support for a firmware "rollback". SanDisk Technical Support 1-866-726-3475 Best of Luck.
