Hello i have the above mentioned PDA running Windows mobile, now i have only been using this pda for my sat nav but decided to use it as an organiser for real. The issue i am having is no matter what i do on the machine, callender, word, excel etc if i do not keep the battery charged or plugged into the mains and it gets flat then every thing reverts back to original, with no record of anythying at all. Is this normal behaviour? it does not eben keep my name on it. Any ideas please.
