Acer is close to its target of becoming number one notebook vendor in the world.
The company reckons its notebook shipments could rise by as much as 40 percent for the third quarter. Notebooks now account for 67 percent of its turnover, up from 60 percent last year.
Sales will be driven by the launch of Windows 7, as well as back-to-school demand, president Gianfranco Lanci told the Taipei Times. China's economic stimulus plan has also helped.
The company said it expects shipments to grow another 10 percent in the final quarter. It's focusing hard on its Atom-powered netbooks.
Acer currently has about 13.5 percent of the PC market worldwide, according to preliminary data from Gartner, with a 20.1 share of the notebook market - making it number 2 after HP. The new forecast means that it could be just a couple of hundred thousand units away from knocking HP off the top spot - its stated ambition.
Late last week, Acer reported first-half revenues of $7.3 billion, down six percent on the same period last year.
