NEW YORK (CNNMoney.com) -- Hewlett Packard chairman Patricia Dunn doesn't plan to resign as chairman or board member, the company said Friday.

Dunn has no plans to step down but would do so if asked by the board, according to HP spokesman Ryan Donovan. HP's board plans to meet Sunday, he added.

Dunn was not aware that "pretexting" was used during an internal investigation into company leaks, HP said.

Dunn has come under fire since HP disclosed that it obtained phone records of its board members and individuals outside the company during an internal probe.

"This problem won't recur," Dunn told Reuters Friday, referring to questionable investigation tactics.

HP (Charts) hired investigators to find the source of leaks about internal board deliberations to the news media, the company disclosed in a filing with the Securities and Exchange Commission Wednesday.

Phone records of board members were obtained during the investigation through pretexting, a practice where someone impersonates someone to access personal confidential records, HP said. The records of nine journalists also were targeted by the investigative firm during the probe, Donovan said.

California Attorney General Bill Lockyer is investigating the tactics HP used during the investigation. Pretexting is illegal in California. HP said it is cooperating with the attorney's general office.

The company probe fingered board member George Keyworth as the source of the leaks. He was asked to resign but refused to do so. Fellow board member Thomas Perkins quit his position on the board in protest of the tactics used in the investigation.

Perkins is seeking a federal probe of the leak scandal, Reuters reported Friday. He has made criminal referrals to the U.S. Attorney for Northern California, Kevin Ryan, and Michael Garcia, the U.S. Attorney for Southern District of New York, Reuters said.

"We have made criminal referrals and our understanding is that they are being investigated and being handled in the normal course," Viet Dinh, Perkins' lawyer, told the newswire.
