All regions showed a decline compared to a year ago. The fall in the Asia Pacific PC market continued, showing five consecutive quarters of shipment decline, while the EMEA PC market registered two consecutive quarters of double-digit decline.

"We are seeing the PC market reduction directly tied to the shrinking installed base of PCs, as inexpensive tablets displace the low-end machines used primarily for consumption in mature and developed markets," said Mikako Kitagawa, principal analyst at Gartner. "In emerging markets, inexpensive tablets have become the first computing device for many people, who at best are deferring the purchase of a PC. This is also accounting for the collapse of the mini notebook market."

Hewlett-Packard (HP) and Lenovo's neck-and-neck competition continued. This time, Lenovo was back in the top position by only a small difference in share. Lenovo showed mixed regional results, as it experienced strong growth in the Americas and EMEA, while showing a major decline in Asia Pacific. Weakness in China was most likely the contributor of Lenovo's shipment decline in the region as the majority of Lenovo's volume came from China.

While HP was slightly behind Lenovo, HP is a market leader in key regions including the US, EMEA and Latin America. Asia Pacific has been a weakness the last three years for HP, but preliminary second quarter results suggest an improvement of their performance in the region.

Dell's shipments declined compared to a year ago, but its second-quarter results showed a smaller decline than the past several quarters. Dell showed good growth in the US and Japan, but struggled to increase shipments in Asia Pacific and EMEA. Both Acer and Asustek Computer showed steep declines compared to second-quarter 2012. The decline was partly affected by their strategies to exit the mini-notebook (netbook) market.

"While Windows 8 has been blamed by some as the reason for the PC market's decline, we believe this is unfounded as it does not explain the sustained decline in PC shipments, nor does it explain Apple's market performance," Kitagawa said.

In the US market, PC shipments totaled 15 million units in the second quarter of 2013, a 1.4% decline from the second quarter of 2012. This decline was less than the past seven quarters, and the market grew 8.5% sequentially.

"Our preliminary results indicate that this reduced market decline was attributed to solid growth in the professional market," Kitagawa said. "Three of the major professional PC suppliers, HP, Dell and Lenovo, all registered better than US average growth rate. The end of Windows XP support potentially drove the remaining PC refresh in the US professional market."

PC shipments in Europe, Middle East and Africa (EMEA) were weakened in the second quarter of 2013, with a 16.8% decline over the same period in 2012, marking the fifth consecutive quarter of decreasing shipments.

"The sharp decline in the second quarter of 2013 was partly due to the shift in usage patterns away from notebooks to tablets, and partly because the PC market was exposed to inventory reductions in the channel due to the start of the transition to new Haswell-based products," said Isabelle Durand, principal research analyst at Gartner. "Touch-based notebooks still account for less than 10% of the total consumer notebook shipments in the last quarter."

"Shipment levels remained weak in Western Europe in the second quarter of 2013 as PC replacement rates continued to be extremely low, while the challenging economic environment is muting spending in consumer markets," said Durand. "Shipments in Eastern Europe also remained low as this is typically a quiet quarter for business buyers in the region, and consumers are predominantly looking for Android-based tablets. In the Middle East and Africa, tablet and smartphone adoption also continued to draw demand away from PCs in the second quarter of 2013."

Despite the steep shipment decline, HP retained the top position in EMEA due to better results in the professional PC market. Lenovo was the only top-five vendor to exhibit shipment growth, recording a fourth consecutive quarter of growth and taking second place in the EMEA PC vendor rankings in the second quarter of 2013.

Acer exhibited the worst performance of the second quarter with a shipment decline of 38.5% on year. Most of Acer's decline resulted from its portfolio shifting away from netbooks to Android tablets. Asustek also experienced a PC shipment decline in the second quarter 2013. The drop of its netbooks continued to impact its overall notebook results.

In Asia Pacific, PC shipments surpassed 26.8 million units in the second quarter of 2013, an 11.5% decline from the first quarter of 2012. All country markets across the region showed weakness, but India performed slightly better due to a state PC tender fulfillment. China's PC shipment remained weak as the consumer market was hampered with lack of new demand generation programs, such as subsidized PC program in the rural cities.
