URL: Dell facing slew of Chinese lawsuits over CPU switcheroo
To some consumers, it may seem like a minor change. Dell shipped the Chinese version of its Inspiron 640M portable computer with an Intel 200M CPU. The marketing materials indicated the model used a more expensive process, the 2300.
The major difference between the two processors is that the 2300 includes hardware support for virtualization. This allows the computer to run several different sessions and operating sessions at the same time with a minimal performance loss, when compared to older technologies such as emulation.
When used in a Macintosh, this technology allows users to run Windows, Linux, DOS, or almost any other operating system while they run the default MacOS.
Virtualization is also a key technology in server deployment. Dell, HP and other computer manufacturers sell large multiprocessor cmoputers that behave as many different servers. Each server runs in its own virtual session, so one large computer can replace several separate computers that were each dedicated to specific functions, such as e-mail, the Web, and transaction processing.
In a consumer-grade laptop, the loss of virtualization is not as as critical as it might be on a server computer.
However, word spread quickly through Chinese forums and web sites that Dell had advertised a more expensive processor than it actually shipped. In Windows, it is easy to check what processor your computer is using, by examining the System Properties box in the Control Panel. Try using the shortcut keys Windows+Break.
Dell managers blame a mixup between manufacturing and marketing, and have offered an apology and full refund to customers. The apology is crucial in Asian markets. However, some litigious Chinese customers have decided to sue Dell’s Chinese subsidiary for damages.
