International Business Machines Corp. (IBM) has reportedly put its personal computer business up for sale in a deal that could fetch as much as $2 billion and close an era for an industry pioneer which long ago shifted its focus to more lucrative segments of the computer business.

The New York Times said in its Friday editions that IBM is in serious discussions with the Lenovo Group (search), China's biggest maker of personal computers, and at least one other unidentified buyer for the unit.

The newspaper cited people close to the negotiations that it did not further identify for the report.

The Times said Edward Barbini, a spokesman for IBM, told the newspaper "IBM has a policy of not confirming or denying rumors."

Spokesmen at Lenovo's Beijing headquarters and Hong Kong offices did not return calls Friday.

IBM has refocused on the corporate server and computer services businesses, but was a major force in driving personal computing into the mainstream with its introduction of the IBM PC in 1981.

IBM, based in Armonk, N.Y., now ranks third behind Dell Inc. (DELL) and Hewlett Packard Co. (HPQ) in the personal computer business, according to Gartner Inc. (IT), a Stamford-based provider of research and analysis on the information technology industry.

The Times said the business up for sale would include the entire range of desktop, laptop and notebook computers made by IBM. The sale would likely be in a range of $1 billion to $2 billion, the report said.

Guo Tongyan, a Lenovo marketing manager in Beijing, said he had not heard of any discussions, but noted Lenovo was building up its personal computer business.

Last month, China's state media said Lenovo and IBM were discussing teaming up to make desktop personal computers.

Asked about The Times report, Guo replied: "If Lenovo wanted to further expand its PC capacity, I wouldn't be very surprised."

"We decided on a strategy of 'reinforcing the PC business, focusing on the PC business' in a strategic meeting early this year," said Guo, who heads Lenovo's northern China marketing department.

Lenovo, formerly called Legend, had begun expanding into mobile phone manufacturing and information technology services when its computer manufacturing business faced intense competition from foreign rivals such as Dell.

But after reporting worse-than-expected results last year, Lenovo said it would return its focus to its core computer business.

Lenovo is the world's ninth-biggest computer maker by size of shipments.
