BIOS | Power On When AC Detected grayed out

[TNS90]

Hello Community,

after trying to reach the HP Business support for several minutes (website only guides me in an infinite loop, after adding my product), I try to get any advice here.

In the BIOS setup of my HP ZBook Firefly 15 G8, the option "Power On When AC Detected" is grayed out (see picture). Is there any way to activate and enable this setting?

Best regards
Tim

I have just found out the solution to the problem.

If you check the "power control" box in the "power management options" (in the BIOS setup), booting when the power supply is connected is disabled / grayed out.
