Hello,
My name is Mike, I'm a Technical Analyst located at Dell corporate headquarters in Round Rock, TX. I'm part of an internet outreach team developed to interact with the online community regarding technical questions and issues that customers face with Dell products.
Dell is aware of the reported finding and plans to recover the notebook from the customer for analysis. All Dell products are designed and tested to meet or surpass applicable worldwide safety and performance standards, including IEC 60950. The compact two-prong power cord used with this Inspiron 9400 is now considered a standard in the industry, and it is sometimes possible that these more compact two-prong power cords would allow the current described by the customer. These industry standard power cords allow Dell customers greater flexibility in finding replacement cords or new cords when they accidentally leave them behind or when traveling through multiple countries.
Based on the information available to Dell in this customer's blog post, we believe that there is no safety hazard associated with the reported "tingling." All electrical devices powered by AC adapters with a two-pronged power cord (without a ground wire) may exhibit a small amount of voltage between the exposed metal parts of the device and earth ground, causing, on occasion, a user to feel a tingling sensation when the user touches exposed metal parts. This is very low voltage and does not present any risk of injury to the user. If any of our customers are concerned they should contact us online at customer_advocate.com.
