I have a TinyBook T706 that I bought used and am unable to get past the initial Windows CE password prompt (which is why it was only $10!).
I have completely taken it apart and reassembled it (one of the easiest notebooks for this ever produced) and this had no effect (I was hoping to reset something).
I am assuming I must zap the OS in some way, but since it is embedded, I don't know how.
Generally, the only way to get around the password is to reflash (re-install) the OS. Unfortunately, neither O-Digital nor its predecessors ever released a ROM image for the device to reflash. So there may not be a solution.
