Patricia Dunn will resign from her post at Hewlett-Packard - but not until next year. H-P CEO Mark Hurd takes over as chairman, as many guessed would happen. She stays on as a director. Dunn is in the middle of a scandal involving the computer company's use of private investigators to get at the phone records of board members. She seemed to be holding her own late last week, but then the Justice Department and a Congressional committee announced investigations into the leaks and the heat apparently became too much to bear.
