Dell-Cares case update - system was returned.
I have a brand new (less than 5 days) Inspiron 14 5000 Series 5402 and I have the same problem.   Background: I had been using it, it was working fine. I have its power cord connected. I close the screen down. And let it sit for 24 hours,   The Problem: I Open the Screen. I press and hold the Power button for a few secs. The keyboard "back lights" behind the keys do light up, but the screen is black. I have tried pressing and holding the Power button.  I wait for 2 mins. Nothing (keyboard remans lighted) I have tried removing the power cord and re-inserting it (the little indicator lights up for 3 secs). but the screen remains black.   I go and search google and no help. then suddenly after 12mins the "Dell" message appears and the  operating system starts up ! I cannot say I did anything to make it come up. It is frustrating. -Gary H
