It seems i have the same problem with you. Black-out occurs in the middle of the boot. At the time of the black screen, i can Print screen by combo key "Shift + Alt + 4" and Shutdown by "Ctrl + Power button" then Enter. Although, i can't see anything but can take screen shot and take a look:Real story like a lie
Premise
1. my Thinkpad Carbon X1 Gen3 is, BIOS is locked
2.Dedicated Video Memory is, is 0MB -> DVMT pre-allocated: 32MB?
3. [GUIDE] Intel HD Graphics 5500 , it has STEP 2.2.
(However, it seems that it has not been set correctly)
What you need
1.CLOVER rev.3202
2.LED access lamp marked with WiFi USB dongle
3. patience (few minutes)

But, it will be sure that the WiFi USB dongle with a LED access lamp rather than a system hang-up is flashing
Wait for 2 minutes
After flashing WiFi USB dongle with a LED access lamp it is calm,

And i think the BIOS is locked so, it is that the rewriting from the outside is prohibited. But i don't have Dongle USB Wifi.
Any idea to fix this error?
