When booting up my Inspiron 16 Plus, I receive an error message: "Fan failed to respond correctly. (Previous fan) Fan Malfunction." The error code is 2000-0712. The Validation code is 122435. This is on the hardware scan portion. There's a button to click to continue, so I do and it works fine. I talked with a Dell Tech and after more than a half-hour of him taking control of my computer and running all sorts of tests, he either hung up on me or we were disconnected, and he didn't call back. As far as I know, the fan is working okay--it comes on every now and then but always goes off. But, while the computer is still under warranty, I'd like to get the problem resolved. Any clues?
