I tried formatting it, updated the firmware to 1.3, copied the Autotransfer file. The on/off button is not responsive. I read something about the chip driver from packard bell but i'm not sure. I know it's an older model, but i'd really like to see it up and running again.</P></BODY></HTML> Wed, 23 Feb 2011 23:00:50 GMT https://community.sony.cz/t5/portable-audio/nwd-b105f-won-t-start/m-p/202364#M1886 pongol 2011-02-23T23:00:50Z NWD B105F won't start https://community.sony.cz/t5/portable-audio/nwd-b105f-won-t-start/m-p/202365#M1887 <HTML><HEAD></HEAD><BODY><P>I encountered same problem.
