Acer has scaled back its expectations in the PC market after an optimistic forecast earlier this year.
It blamed Microsoft for failing to push up demand for its latest operating system, Vista.
Acer, which was recently ranked by Gartner as the third largest PC vendor behind Hewlett Packard and Dell, said it now expects sales growth of 30 to 40 per cent, according to reports.
Previously, the firm had issued bullish revenue expectations for sales growth of more than 40 per cent.
According to the United Evening News in Taiwan, chairman JT Wang was quoted as saying that Acer's second quarter sales to June were likely to come in flat.
El Reg is awaiting comment from the firm. ®
