That is certainly concerning.  The way I understand from reading your post that the system doesn't shock you while you are using it under battery only and don't have the AC adapter plugged into the system. 

If my understanding is correct please reply back with the part number, model number and any other information that you can read from the AC adapter. I also want to know if the AC adapter has a two prong or three prong plug.  If it is a 3 prong adapter are using using some type of adapter so that you can plug it into a 2 prong power outlet?  Have you tried the AC adapter on another power outlet and did you notice the same probem?

I look forward in hearing back from you soon.

i am facing the same problem in my xps 15. And you know what it all happens due to its aluminium body. We will get these electric shocks wherever there is not a proper earthing. Although it comes with a 3 prong adapter but it wont help in any way when there's no earthing the power socket. Even when you will connect a modem or anything that has a 2 prong adapter,it will give u mild electric shocks. So its a serious desighn flaw and atleast the area aront keyboard should be of plastic only instead of aluminium. Thumbs down - Dell!

oops! i am sorry to hear that. Well i am still facing the same problem too. I dont get shocks at some or very rare places where the earthing is done in a 100% proper way. Rest i prefer to charge it and then only use it on battery mode so that i can get rid of electric shocks. That is really bad.

I am sorry too. Same problem here with my new Dell XPS 15 L502x. Mild electric discharges/electric shocks at the aluminium case.

Support desk, attended my inquire politely and quite fast. They shipped a new adapter that has arrived today. It does resolve the issue when the socket I am plugging the laptop into is earthed but when I use a socket with 2 pins the problem returns.

That is really dissapointing because most of the sockets in our house have 2 pins.

I wonder if is a fact that with these model we will experience this annoying and unplesant issue whenever we are using a 2 pins socket? That would not be acceptable for me.

Even my metal toatster or microwave doesnt give any electric discharge in a 2 pin socket :emotion-1:.. and they run with a lot of power. Beyond any joke I am worried about my lappy :emotion-6:.

I contacted the support desk again, and I will let you know which the final result is.

PS: I am in europe... so no adapter is needed for plugging a 3 pinned plug in a 2 pins socket.

I AM ALREADY USING A 3 PIN ADAPTER BUT WHAT'S THE FUN USING IT WHEN THERE IS NO EARTHING IN THE SOCKET ITSELF. I GUESS I WILL HAVE TO STICK WITH IT.

I agree with you... Moreover, most of our socket (except for the ones in the kitchen and the garage) are not earthed (2 pins). So, is not fun, I think that is really a serious issue. Electric current flowing trough your body should not be a good thing. 

I am waiting for their reply, if there is no solution I hope they will take the product back and refund my money... Although is a really nice laptop and I love the sound, there are other nice options too...

Well, here is the answer from Dell:

"I will have to inform you that the XPS L502X systems were designed for grounded sockets and I can do nothing with it.

Thank you for your comprehension."

If you guys don't have a grounded socket, try discharging the laptop yourselves with any metallic object in contact with a neutral surface. It is not uncommon for electrical equipment to build up a small static charge if not grounded. Having said that, these electrical shocks are nothing to worry about, and at most a minor discomfort.

Terex2011 thanks for your reply.

The discomfort is exactly the point, you should know bedore  buying a 1200 dollars laptop that you will feel "DISCOMFORT" every time you are using it (if a proper erhing is not available at your socket).

I'm curious to know how many old houses in the USA have no grounded power points. I can think of much more dangerous situations when a highly powered electrical appliance, e.g. a hair dryer, is not grounded and a wire come loose... You might want to have an electrician come by to install some grounded sockets for your own safety.
