Lenovo has continued to outpace its competitors. The world’s largest PC maker also posted gains in the vital U.S. market, where it jumped from No. 4 to No. 3 – behind HP and Dell – in the rankings issued by market research firm IDC.

Lenovo, which moved past HP last year to become the undisputed No. 1 in the worldwide PC market, is based in China but has a headquarters in Morrisville that employs about 2,200 workers. Lenovo’s local presence is expected to double when it completes its pending $2.3 billion acquisition of IBM’s low-end, x86 server business.

Several factors have contributed to Lenovo’s surge, said Loren Loverde, a vice president at IDC.“I think they have a great brand and a great product, to begin with,” Loverde said. In addition, “Lenovo has been fairly aggressive in introducing new designs.”
