My Sansa Fuze won't turn on, even when connected to the computer

 Thanks for the info folks. My daughter received this fuze for Christmas and it got wet enough to fog the screen just a couple weeks after she got it. Well everyone had given up on it, so I took it and let it dry out really well, followed your advice about holding the power button on for 15 seconds ( it wouldn’t respond to anything before ), and viola… Its working fine now. Thanks to everyone.
