I toyed updating my BIOS and afterwords the computer did not show the Dell logo, just a black screen. And yes, I have tried unplugging and plugging the display in, which was a pain with the connecter inside on the laptop.What, if anything, changed with the laptop before this happened? What makes you think the BIOS is corrupted?
Plugging/unplugging the display serves no purpose, especially on a laptop where you are likely to damage the system doing so.
Were you attempting to update the Dell BIOS? Did this laptop have a BIOS password set for it before you attempted to change?
Have you contacted Dell about this matter?
It is still not workingWas the BIOS update successful (did the process complete)?
Did you try any of this?
