More than 50 Chinese consumers have submitted complaints online accusing Dell (DELL) of providing the wrong CPU in its laptop computers.

The problem was first identified by a consumer who bought a Dell Inspiron 640M laptop online. When the consumer tried to upgrade the EMS memory within the computer, he found that the laptop was fixed with a T2300E CPU, not the T2300 Dell marked on the order form.

50 other users responded to this consumer and said they had identical problems, and they are working together to sue Dell for compensation.

The CPU Inter T2300E is CNY300 cheaper than T2300, and it can not support some virtual technology.

Dell says there is no difference for consumers using CPU T2300 or T2300E, and they will not reimburse consumers for the incorrect configuration.
