zbook x360 screen goes black

[klamia71]

my screen goes randomly black , still the pc is working.

when it comes back there is no way to   change or dim brightness . to do so i have to reboot my pc.

some times also my screen goes black and i cant do anything and the only way is to reboot my pc.

it seems that is graphic card issue . my drivers are at the latest versions.

I think it's a Windows 11 Video Display Driver Issue. Have you thought of rolling back to Windows 10 to see of it will fix the problem.
