I have a Dell Latitude E5450 laptop with the docking port on it.

after an automated update through the dell update utility i found out the the usb3 ports at the back- wifi and 4g wwan cards are not detected anymore and the screen goes blank after a few seconds after boot

i found out the the bios for 5450 the version without the docking port was installed but i can not revert to the correct bios since when i try to manually update the bios i get a wrong hw id error message

any ideas?
