I too am the new owner of Nokia N800. After charging the unit I turned it on long to restore previous Nokia data and then stupidly turned it off. Now I cannot turn it back on. I have read through this thread and tried everything suggested to no avail. I sent Dell an email asking about how to exchange it. (Assuming I can). If not I'm stuck. Any thoughts? I have tried charging, battery in and out; battery out and wait (the longest is overnight). Still nothing! When it charging there are lights, or icons just a a dark screen. Any insight is welcomed.
Thanks.
