Western Europe PC sales fell again in the three months to the end of September, and the market won't rebound for another 12 months at least, market analyst IDC has warned.
Shipments fell by 12 per cent overall, with Dell again the only top five vendor to increase its numbers and market share.
Last week IDC said global PC sales fell by 10 per cent.
IDC said that a fall-off in corporate sales triggered the decline, and that this may have been accelerated by the terror attacks of 11 September.
It does not expect the sector to pick up again until the second half of next year, and also warned that a hoped-for Windows XP inspired sales boost was unlikely.
IDC said: "Corporate investments were heavily affected by an increasing squeeze on budgets, with many companies putting on hold non-essential renewals and large projects."
The analyst also warned that PC replacement cycles were being increased from three to four, or even five years.
Desktop sales fell hardest, by 12.5 per cent, while laptop sales held steady.
Compaq retained market leadership in both markets, with a share of 14.5 per cent (down from 15.5 per cent) on shipments that were 15.7 per cent lower.
Dell, whose cost-per-unit was described as "in a league of its own", moved into second place.
The firm shipped 6.6 per cent more PCs, increasing its share to 10.4 per cent (8.9). Fujitsu Siemens and Hewlett-Packard followed with 8.5 per cent (10 and 7.9, respectively) with IBM on 6.6 per cent (8.3).
Europe, Africa and the Middle East slightly offset the 12 per cent decline in Western Europe. For the entire EMEA region, shipments fell by 9.5 per cent.
The market decline has also hit Asia. For the Asia Pacific region as a whole (excluding Japan), the market fell by one per cent.
The figures were helped by an increase of Chinese PC sales of 8.2 per cent over the three months to June, but even this fillip was a disappointment. Analysts had hoped for an increase of 20-30 per cent in China.
