problem with e250

hello i have got problem with my player when i connect it to the computer its being recognized and battery is full

thanx in advance

Is this the same problem with the same player you posted about 10 months ago here?

The same advice you were given then would still apply. It’s a battery issue:

  1. Dead battery,
  2. Faulty battery connection, or
  3. Faulty battery charging circuitry.
