Well my MpMan MP-E2004 works, but i dont know how to switch it on because i dropped it a couple of times and all the buttons seemed to fall off one by one, but the inside bits of the buttons are still there and work too. I last used it over 3 years ago i France that's why i don't know how to switch it on.

SAME THING HAPPENED ON MY MP3 I FORMATTED IT BUT IT WONT PLAY SONGS TRY FORMATTTIN IT USING WINDOW

This player, oddly enough, only works with regular XP/SP1 - probably the only mp3 player in existence that is like that. I think the company's phrasing of the problem is quite humorous:

If you have WindowsXP SP2, we recommend that you go back to Windows XP SP1 before Microsoft solves the problem.

maybe you have loose connection! at the port connection! you can re solder it!

I had a similar problem with a MPMan. It seems the mains charger supplied with it simply does not work. Try charging the player by connnecting it to a USB port of a running computer and leaving it there for several hours. It may then work!

If you couldn't find the firmware, here's a link - http://www.mpmaneurope.com/download.aspx?file_id=205 If the reset procedure suggested in the manual doesn't work, try taking out the battery for a day or two, that should also reset it. try switching the battery with another one. If it starts up when you connect it to the power cable then the battery or power supply system is at fault. If you still have a warranty, use it, if not, think how much a repair is worth for you and consult the shop you bought it with, or a similar shop that sells these products. Good luck
