My mp3 player will not turn on

You could try the following:

Start with the Clip turned OFF. Slide the power switch down to the HOLD position. Press and HOLD the center button depressed until it is recognized by the PC- give it a few seconds.

The Clip's display will state "connected" with the device now in MSC mode.

You can now repair the File Allocation Table (FAT) using Windows' chkdsk utility.

Open My Computer and find the Clip a listed under "devices with removable storage" as a flash drive. Let's say it displays as E: SANSA CLIP for example. Our assigned drive letter is E:

From the Run box under Start, enter cmd and press Enter. You will get a DOS window.

Enter chkdsk E: /f and press Enter. The /f toggle tells the utility to fix the errors.

After clicking on the Safely Remove icon in the taskbar, or right clicking on the Clip and selecting Eject, unplug the Clip.

Try powering it up again, and see if all is well.

there is no need to install it just go to control panel and click on portable media devices

either you have a bad usb cable, or you do not have the newest drivers installed.

this should fix it, a tiny software that fixed mine just fine

USB 2.0 only.

The headphone jack is faulty - replace the player - find out from Sansa if you are in-warranty.

Surprisingly the solution was quite simple after I stopped panicking. The Sansa Updater Setup Maintenance Program, I don't know where I got it from, probably off the web site for Sansa. I clicked it, followed themessage to delete current files and update new material. It told me to plug in my "dead" Sansa Clip (which was full of audio books I did not want to loose) and like magic it came to life. I sure hope this information helps someone. I have the silver 4g SanDisk and LOVE it

hold the volume button + - at the same time, and push the power switch up
