HP was still the favourite vendor in the US market, followed by Dell and Apple.
PC shipments in the AP region increased by two percent to total 30.3 million units.
Japan, which is largely considered a separate region in itself apart from the AP region, saw an increase in PC shipments to 11.5 percent. But Gartner said this is due mainly to the fact that market performance for the first quarter of 2011 was "very weak" because of the earthquake and tsunami that struck the country in March 2011.
Kitagawa also noted market developments that affected the first quarter results.
"The first quarter of 2012 was a transitional period as the PC industry is awaiting two big releases: Intel's Ivy Bridge and Microsoft's Windows 8. Both are expected to be launched this year. Although these new releases are not expected to stimulate demand as much as the industry hopes, they will affect PC supply so that there will be artificial supply control before and after the product releases. There will be few products rolled out into the market until these major releases have taken place," Kitagawa said.
