Dell bumped up its savings goal to $4 billion in February and indicated the additional cuts would come from both and supply-chain improvements.

Dell was already struggling with ever-slimmer margins as PC prices dropped, but the economic crisis has added to its troubles as both consumers and businesses are postponing purchases.

The Round Rock, Texas-based company has begun shifting work from its own factories to less-expensive contract manufacturers and has said it is reviewing all plants and operations. The company has not publicized a new target number for layoffs or discussed plant closures.

Dell opened the in 2005, after state and local officials promised worth more than $300 million. The company planned to invest $100 million and create 1,500 .

Dell spokesman Jess Blackburn would not say how many of the North Carolina workers would lose their jobs Wednesday.

In Tennessee, some of the 3,000 people employed in two Dell facilities were also laid off Wednesday, but company spokesman David Frink declined to say how many. The PC maker operates a technical support call center, sales operations and a distribution center for the eastern U.S. in Nashville and a desktop computer manufacturing plant in the nearby suburb of Lebanon.

Frink said the employees were offered "competitive" severance packages.

Neither spokesman would say where other layoffs were taking place or what percentage of Dell's overall work force they represent.

Shares of Dell gained 22 cents, or 2.5 percent, to close at $8.98. Hewlett-Packard Co., the No. 1 computer maker, rose $1.57, 5.8 percent, to $28.61.
