Hi,
I have a Dell E7240 i7 vPro touch FHD computer. I got it with bios A04 installed. (win 8 pro) everything works fine. After when I update to A14 and install win 8.1 pro problems comes. No any screen until windows booted when computer docked (no dell logo or any post message, monitor in sleep mode). Intel management engine interface also stopped working and device manager shows exclamation mark (status_power_faluire) When I try to downgrade to any version computer only restarts and do nothing.
I enabled bios downgrade in bios, tries any way. Under DOS, under boot manager, under windows. Same (computer only restarts and no change) I tried with uefi and legacy bios as well.
Please somebody have any solution?
Thanks
