Intel has cut its profit forecast after warning sales of computers were weaker than expected.
The chipmaker said it now expects revenue of between $US10.8 - $US11.2 billion in the July - September period, from a previous forecast of $US11.2 - $US12 billion.
Intel is the world's biggest provider of the microprocessors.
The BBC reports this is traditionally a time for strong computer sales as families buy laptops for children going back to school or college.
But Intel said it was seeing "weaker than expected demand for consumer PCs in mature markets".
Last week, PC maker Dell gave a similar message while Hewlett-Packard said it saw some "softness" in the consumer laptop market.
