Lenovo climbed back to the third spot in the global PC market in the second quarter, achieving 22.9 percent growth in the three months to June, the largest increase among the top 10 PC suppliers according to the latest data from research firm iSuppli. By comparison, Acer unit shipments fell by 10,000 for the first time in several quarters.

Lenovo’s accomplishment was described as “remarkable”, given that overall shipments declined 1.7 percent during the period. But iSuppli predicts Lenovo won’t last for long in the No. 3 spot, as Acer’s planned acquisitions of Europe’s Packard Bell and North America’s Gateway should help the company to gain approximately 2.5 percentage points of market share.

Following a period of market share losses, Dell finally posted a 5.6% sequential increase in shipments. Although still down by 5 percent compared to the second quarter of 2006, the company managed to take back 1.1% of global market share. Meanwhile, HP held on to the top spot as it increased market share from 17.2 to 18.3 per cent quarter-on-quarter. You can read the full press release at our forum.
