I will try and explain the two scenarios that I have experienced: The first which has happened a few times, The fans go maxed one at a time from left to right for a second or two. It sounds like the wind. I just got this notebook, so I am not sure if this was part of the fans control process, etc. The fans blew a lot of air, because I could seriously feel it come out the back. Three or four times in a 20 hour period, I think.
I ran dell's diagnosis process, and everything passed, was just doing checks not for this issue. In any case, BIOS needed updating, the process installed one, and said I had to manually install the other one. When I clicked to execute, the fans maxed out again and this time for almost as long as the install took for the bios update.
The notebook restarted, and all is cool, but its only been a few hours at best. Anyone had issues like this, or ideas as to what is causing this issue?
