Of late, HP has been No. 2 to Dell on the worldwide PC market. But in Asia-Pacific it took the top spot, garnering 11.7 percent of the nearly 9-million-unit quarterly market. The company registered a 28.8 percent year-over-year increase in unit shipments for the January to March period.

Lenovo came in a close second with 11 percent of the market. The company's number of units shipped grew by 20 percent.
Overall PC shipments to Asia-Pacific totaled 8.9 million for the quarter, a 13 percent rise compared with the first quarter of 2004 and slightly above IDC's forecast, the market researcher said in a statement.

Third-place Dell had almost 8 percent of the Asia-Pacific market. But the Round Rock, Texas, company showed the largest unit shipment increase among the top five in the region, a 29.1 percent increase for the quarter.
IBM had just over 6 percent of the market, but its shipments fell 2.2 percent from last year, IDC said.
Founder rounded out the top five with just over 5 percent of the market. Its shipments for the quarter jumped almost 23 percent.
