I purchased a very expensive (.$2000) Alienware M15 laptop.  It came with a Chinese power adapter made for a Chinese outlet.  I contacted customer service.  I was initially told that was just my problem and to purchase a plug adapter from the Dell site.  After I insisted that was unacceptable, I was shuffled to customer service.  I had to send pictures 3 times of the wrong power source.  I then dealt with Adarsh_M for over a week.  His emails were of course very nice, but he simply could not help me.  He kept showing me incompatible parts, and I had to explain to him multiple times why the part he was offering me was wrong.  He finally offered me $45 credit to find my own part, which was ridiculous.  I sent him a very clear picture of the American 240W adapter I needed, and asked him to ship it to me and I would return the Chinese adapter.  He then sent me a picture of a 180W adapter he wanted to send.  For 10 days I have been unable to use the laptop.  The customer service is nonexistent.  I am beyond disappointed, and anyone thinking of purchasing from Dell should learn from my experience.
