I would first like to start by apologizing for the delay in response to this thread. Numerous departments including engineering, product development, product design, and other technical analysts here at Dell have weighed in on this discussion and it’s taken some time to accurately organize all of the information. Dell wants to be very clear about what the reported “tingle” effect has on the end user and the machine.
In reading the thread since my last post, the concern seems to be focused on:
-Is this a safety issue?
-Will this voltage damage the internal components?
-What’s causing the “tingle” effect?
Please bear in mind while reading through this that Dell does not endorse, condone, promote, nor advise any customer attempting to take any sort of electronic readings without the help or guidance of a trained professional. Great care must be taken when dealing with internal electronics as an untrained person can damage the computer, the device used to measure electricity, or, more importantly, hurt themselves.
We will have a more detailed explanation posted on our Dell blog
next week, but here are some points I’d like to confirm:
-The voltage is not harmful to the user.
-It is not harmful to any of the system’s internal components.
-This issue is not specific to Dell.
-This issue is not specific to notebook computers at all. (It can be felt on many electronic devices that use a 2-prong AC power source under specific environmental conditions.)
Several regulatory and safety agencies are in place to create and maintain standards for electronic devices. Please keep in mind that Dell meets or surpasses all applicable standards with all of our notebook and desktop systems. The logos of the applicable regulatory and safety agencies for the Dell notebook power adapters can be found on the AC adapter power brick and include the FCC, UL, CCC S&E, CSA, CE, IDA, IRAM, GS, NOM and a few others. The most important one to note will be a picture of a square within a square which indicates double insulation. Double insulated refers to a safety method to protect users without an earth ground. This is done by using non conductive outer layer(s). Given the correct environmental conditions the “tingle” is inherent of double insulated equipment. Delivering safe electronics has been a priority since Dell’s inception and we are committed to meet—and exceed—all regulatory safety requirements with our products.

Thank you for your patience with this issue. Again, we will have a post with more details on the Dell corporate blog, www.direct2dell.com
next week. I encourage you to continue the discussion there if you have any further questions.
