My sansa e200 is frozen and none of the buttons work

It could be that your HD is going. Although you might want to reset it.

Hold the middle button and the menu button until it turns black with the Apple in the middle.

This could have been caused by unplugging when it was not ready to be ejected.

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....

All you reaaly have to do is let the battery run out. Then once the mp3 is dead, charge it. The screen should be unfrozen.

hold the menu button for about 15 sec. and it'll turn off

I was told to hold the power button for 20 seconds, this should reset the player. then turn it on and it should work, mine did. hope this helps

just hold the power button until it turns off. It worked for me.

have you tried restarting it?
