Lenovo likely saw buying the 51 percent stake as a chance to grow its own PC division. According to Bloomberg, Lenovo Chief Executive Yang Yuanqing is taking costs out of the company's mobile business, which still hasn't gone anywhere despite acquiring Motorola from Google in 2014. The Chinese tech titan is more known for its computers than its phones, after all. And even though PC shipments have grown by 17 percent from the past quarter, the market is still struggling in the era of smartphones.

Earlier this year, HP overtook the Beijing-based corporation to become the biggest PC maker in the world, thanks to its excellent performance in North America. Depending on how Lenovo plays its cards, this purchase could help it retake the throne it sat on for years.
