I'm on the same boat!!!
My BIOS is dated 1/25/2018 where the new BIOS release date is 5/23/2018. I keep installing it but it's not working. We seriously need help ...
I cannot believe that no one from Dell replied to this and gave us and update or a solution to this problem.
What the **bleep**! This is so frustrating. My laptop has been crashing lately, and I just got it back from Dell after getting repaired cause the in house support guy came to repair the speakers and <Substitute character removed> my laptop! Where is the love Dell?? Where is the love!?!?!
