Hi!

I have 10 laptops Hp ProbookX360 G1 EE with the same issue.When i power on the laptop before entering windows 10 screen goes black.I then press power button once and backlight powers off.Then i press power button again and i can boot to windows.I don't have this problem on restart or if i close the lid and power on the laptop.The problem appears only when the laptop boots from off state and before entering windows.I updated bios to Latest V1.35 and i downloaded official vga intel drivers from the upport page of the product.I also tried and with hp assistant.Lastly,if i use the basic microsoft vga drivers i don't have this problem.Thanks!

I also notice that this problem happens only when laptop runs on battery.If i have the charger plugged in laptop boots normally.

I finally found the answer and i am posting it in case someone else has the same problem.

The solution is:

in power&sleep menu you go to additional power settings
then choose what the power buttons do

then press change settings that are currently unavailable
and uncheck turn on fast startup(recommended)
