Frozen !!! My sansa c150 2.0GB mp3 player is frozen!! nothing I do works!! I've tried taking out the battery and putting it back in, but it's still on the same screen!! I've pressed every button and held down each of them to get some sort of response and nothing happens!! I can't even hook it up to my computer because nothing happens at all, its like its not even connected! my computer doesn't even detect it and the mp3 player's screen doesn't change at all!! When I switch it on it appears with the welcome screen and keeps flashing and I need to take off the battery to switch it off the power button does not work only hold button works and it appears with the lock.. Please help me out!!!!!!!

Go to this guys profile and see if his tip is the answer. Sansa Mp3 player frozen? How to reset and... Hope this helps.

try reseting it. hold down the power button for15-20 seconds and release

With the Sandisk you can just open up the battery compartment and pop the battery out for a second, then if you put it back in and turn the mp3 player on, it should work just fine. This is easier to do with the older ones that take AAA's, but unfortunately with the e250 you need a little screwdriver to remove the battery. (But the other day I used the flat part of a piece of jewelry; you can use whatever you have :D )

mee too!

Have you tried taking out and reinserting battery? That worked for me.

take the battery out

I had the same problem with mine freezing. It happened when I kept pressing the back track button (on left side) to go back to an earlier song. It then froze in the middle of a song, couldn't hear the song, the time of the song was frozen, etc., and the unit stayed lit, despite pressing all the buttons. I tried holding down power but nothing happened. I read another person's post that you need to hold it down 15-30 seconds. I did this and it worked, you just have to hold it down until it shuts down, which was about 15 seconds as suggested, could be longer for others.
For me, next time I wont keep clicking the tracks repeatedly, I'll simply go out of the song and back to the song I want through the menu.
Thank you for the good posts. Glad I didn't have to mess with the battery like others....

Try removing the batteries to force it to shut down. Wait about 30 seconds, then put the battery back in. This will force the Sansa to restart, after which it should work.

Sounds like it may be frozen.

Press and hold the power button for 30 seconds, then try turning it on.

If that doesnt work, remove the 4 screws on the back and take out the battery. Leave it out for a minute or two, then put it back in place and try powering it on.




Best of Luck.

DEFRAG IN MSC! Then check, then format.
