Lenovo, the world’s fourth-largest personal computer maker, on Thursday said it was in talks over a possible acquisition after its shares jumped on speculation of a deal.

“The directors confirm that the company has certain preliminary discussions with independent third parties regarding potential investments opportunities and acquisitions,” the Chinese company said , without naming potential acquisition targets. The move comes as Lenovo attempts to reduce its over-reliance on corporate business, which has been hit hard by the global economic crisis.
