just a mark that i tested some more stuff : [br]
[br]
it started black, i can see minimal flickering by turning it on, so pretty sure display is working,[br]
also hdmi external monitor is showing active connection but no signal.

[br]
there is no boot screen whatsoever, and no other screen shown - simply black[br]
removed the battery and the bios/rtc (?) battery - no effect whatsoever. [br]
changed ram, no effect[br]
no beep - normal lighting [br]
[br]
in the end, it turned out the Chip from touchpad burnt through (realy a hole inside) - with a burnt through lane in the connector cable - guess these made some pretty shortcut loop / hangup [br]
[br]
as i removed the touchpad incl connector screen comes back. So solution for error hunting would be to disconnect all the externals , leaving only keyb(oard) and display - RAM [br]
[br]
i also removed the battery (which is on the downside of the motherboard) - not sure what that may have affected[br]
[br]
beside that there was secure boot with usb boot disabled, which meant i only could boot from an usb drive formated as cd/dvd  (like dd some DVD Lubuntu iso directly to the usb stick) [br]
on top , only one of the usb ports (not the blue usb3 port) was able to boot from[br]
