Hold on to your 1.0.14 BIOS. 

AGAIN, I have issues with CPU overheating when updating to 1.0.16 and 1.0.18. I've also read machines bricking themselves during the latest update. Dell was of no use when diagnosing my issues when 1.0.16 came out. My CPU temps bounce all over the place and my CPU fan is pinned out all the time. Today I tried 1.0.18. SAME PROBLEM. I am now back to 1.0.14 where my computer behaves like it should. My advice, do not update your BIOS beyond 1.0.14. CPU temp issues combined with threads of peoples machines bricking themselves = NO CONFIDENCE IN DELL.
