Lenovo Group Ltd. is a leading global manufacturer of personal computers (PCs). The company was already the largest PC manufacturer in China when it acquired IBM's Personal Computing Division in 2005. In addition, the parent Lenovo Group produces PDAs and mobile phones, and operates consulting and Internet ventures. It has several manufacturing sites in China in addition to IBM's former facility in Raleigh, North Carolina.Like many other high-tech start-ups, Lenovo grew from modest origins. The Zhongguanchun district of Beijing had a reputation as an electronics black market; the area would eventually be called the Silicon Valleyof China. Lenovo is a spinoff of the Legend Group, which was established in 1984 by a group of eleven computer scientists led by Liu Chuanzhi. Liu managed with a very authoritarian style, at least in the beginning, according to later interviews.
