Hewlett-Packard chairwoman Patricia Dunn is clinging to her job as she was battered with accusations that she ordered a probe in which board members and reporters were illegally spied on. California Attorney General Bill Lockyer vowed to prosecute wrongdoers at the end of his investigation into whether private detectives hired by HP impersonated board members and journalists to get private telephone records. Dunn had detectives hired to ferret out who had been leaking information from board meetings to members of the press, according to the veteran Silicon Valley computer company.
