I have laptop Asus PRO79I and i turned on bitlocker on drive D and when i restar a computer monitor is dead,the laptop is runing but screan is black,and i can`t enter in bios mode,nothing....help,please....

Hi, if you disconnect the disk, would you see the Bios screens then? If also not, the fault is coincidence, I would assume and has nothing to do with enabling Bitlocker. Best greetings from Germany Olaf

thx for your answer,bat i can´t take out the disk because it is a laptop and heve warrenty still,whay i even mess with that... regardas form Croatia.

For the most laptops you only need to remove one screw to be able to pull the disk out - for some others its more complicated. Besides that, are you sure, that you did not touch the hotkey shortcut on your laptop keyboard to switch to external display? Did you try (if possible) to attach an external display then?
