With the second-quarter shipments of Taipei-based Acer marking the first quarterly gain for the company in two years, the third-ranking computer manufacturer grabbed 11 percent market share during the quarter; and thus recorded a turnaround from its first annual loss in 2011.

According to the statistics shared by data researcher Gartner on Wednesday, Acer outperformed a 0.1 percent computer industry decline during the second quarter, to climb 3.6 percent year-on-year; thereby recording its first increase since the same quarter in 2010.

Going by the Gartner data, Acer, with an 11 percent market share during the second quarter, overtook Dell - which reported a 10.7 percent share - to grab the third position worldwide, behind Hewlett-Packard and Lenovo Group.

Meanwhile, the other Taipei-based computer maker Asustek reported the fastest growth in second-quarter shipments among the top five computer manufacturers in the world.

With Asus' shipments increasing a notable 38.6 percent during the quarter, Gartner statistics revealed that the company grabbed 7 percent of the market, with the figures indicating a two-fold increase from the 3.5 percent market share which the company held three years back.

Overall, as per Gartner's calculations, the global PC shipments held up better during the second quarter, and dipped by barely 0.1 percent year-on-year. As such, the 2012 second-quarter marked the seventh successive quarter during which worldwide PC shipments either plunged marginally or showed a slight increase over the same quarter year before figures.
