Let me just first say that if you need to have any dealings with Dell support make them put their agreement in writing.
My wife, against my advice, purchased one of those Duo junk boxes. It was nothing but trouble right from the start. It almost immediately started spontaneously shutting off, not down, just completely off like a light being shut off. I called Dell support and they walked me through the diagnostics process (which all checked out good) and then finally ended up doing a system restore. They said it was because my wife was closing the lid before it had fully shut down. Of course the problem persisted and over the course of the next several months I sent it back to them twice. When I last sent it back to them we were approaching the end of the warranty period. The support tech assured me that if the problem persisted they would repair it free of charge warranty or not. I made him repeat that promise twice so we would be 100% clear.
Well, the problem has persisted and now they are refusing to repair it free because the warranty has expired. Big surprise there. Dell is just continuing their slide into the position of worst computer manufacturer in the business. Not only did they market one of the worst products, the Duo, but also are unable to repair it and unwilling to support their faulty products.
Dude...............don't buy a Dell.
