The global PC market racked up 68.5 million units shipped during Q1 2015, a 6.7 percent year-over-year drop, though was still better than previous estimates, according to the IDC research group.
Lenovo has 19.6 percent market share, ahead of Hewlett-Packard (19 percent), Dell (13.5 percent), Acer (7.1 percent) and ASUS (7.0 percent), according to IDC figures.
"Despite the decline, PC shipment in the United States declined at a slower rate than all other regions in first quarter, outperforming worldwide trends for the eleventh consecutive quarter," said Rajani Singh, Senior Research Analyst of the Personal Computing division at IDC.
The PC market is expected to receive a strong boost when Windows 10 launches later this year, as IDC says the new OS "will consolidate the best of Windows 7 and Windows 8.1."
"We have had remarkable growth across all our businesses and success in building the Lenovo brand," said Yang Yuanqing, chairman and CEO of Lenovo. "I am tremendously proud of our broad success. Even as we continue to diversify and develop additional growth engines - like Mobile and Enterprise - we are fully committed to continuing to lead the way in PCs."
