Well it seems that my Clie has finally giving up life. I noticed before that when it was fully charged, a day later or so (without any use) the battery was totally empty. Now it happened again, just want to turn it off - dead.
I don't think that it was any mishaving app because I haven't installed anything new in years and before things have always been fine.
Oh well. It came without warning. Should it rest in piece. My good old Clie 760.
The question is, what will by next PDA...
