Laptop power up
i think it waiting for something
trying to read dvd and hdd
screen is black
when hitting enter hdd led flash (but only 2 times) when reboot it again flash when pressing enter
i think i nid to provide any secure boot key or idk
i tried to restore bios but changing extension to .bin and putting it on fat16 pendrive
it dont work, screen all time is black

That wont work as laptop obviously does not post. I have repaired same problem on same model by desoldering bios chip and manualy programing last 2.5mb in that way serial number and other things like windows license key are kept intact. Dont know if there is way to recover in some other way though.

is there an default secure boot key?
i just enable secure boot and this key thingy then rebooted
when pressing ctrl + home at start, reaction of laptop is "other" idk how to call it
backlight turning on later etc
when i once press power button it shutting down after while by it self
no needed to hold power button

Then you are in some semi brick limbo. Sorry but I dont have any other ideas. But it hears as you have same problem as the one I fixed when I bought my g750jx and seller couldnt tell what happened he said it just died after restart.
