PC sales for the second quarter in Western Europe are radically down on 2010, declining 18,9% to 12,7-million units.

“The PC market in Western Europe suffered from weak demand in both the professional and consumer sectors, a market which also faced inventory issues caused by overstocking in 2010,” says Meike Escherich, principal analyst at Gartner.

The mobile PC market was particularly hit hard with a 20,4% decline, as mini-notebook shipments decreased 53%. Desktop PCs declined 15,4% year-on-year.

“The much anticipated uptake in the professional segment, in the wake of migration to Windows 7, was subdued by the negative economic outlook,” says Escherich. “PC shipments in the professional segment declined 9% in the second quarter of 2011. The biggest decline continued to come from the consumer segment which decreased 27% year-on-year.”

In the second quarter of 2011, Acer lost its number one position as a result of significant inventory adjustments and a decrease in mini-notebook sales. Acer’s weak performance resulted in HP moving to the top spot, while Dell remained in the number three position. Asus shipments declined 22,9% as consumer demand remained weak and mini-notebook shipments fell rapidly.

“This quarter’s results highlights the ongoing weakness of consumer demand, and could indicate a structural change in the market that threatens to continue in the near future,” says Escherich.
