Beijing, China ? Apple Computer Inc. investigated claims of poor conditions at a Chinese iPod factory and found no forced labor but said some workers exceeded the company’s limits on hours and days to be worked.

The company said it was taking immediate steps to resolve that and other issues.

The probe by Cupertino, Calif.-based Apple was in response to a recent report by a British newspaper, the Mail on Sunday, alleging that workers at the factory were paid as little as $50 a month and forced to work 15-hour shifts making the popular entertainment devices.

The probe did find that in many cases workers were exceeding the company’s limits for overtime, which specify a maximum of 60 hours or six days a week.
