Dell, the world's largest computer manufacturer, is facing legal action in China over allegations of false advertising.

The group has been sued over charges its laptops contained a different, cheaper chip than those advertised.

According to state media reports at least 20 lawsuits have been filed against the Texas-based firm.

In a statement on its Direct2Dell website, Dell admitted it had made an "unfortunate and unintended marketing mistake" and apologised for the error.

Dell said it had contacted customers and explained the difference between the two chips and offered full refunds to any customers who were still unsatisfied.
