Lenovo Chairman Yang Yuanqing listens to a question during the Reuters China Century Summit in Beijing September 6, 2006. Lenovo Group Ltd., the world's third-largest personal computer maker, said it would take three to five years to regain the healthy profit margins it had before its purchase of IBM's loss-making PC arm. Yang also said at the summit that Lenovo expected to beat growth in worldwide global shipments as it branches out to cater to small businesses and consumers. REUTERS/Claro Cortes IV (CHINA)
