HP Hotkey Support
Dev. Man.Hi volks again since years!
I bought a refurbished HP EliteBook 755 G5 and installed the W11 from the scratch.
The Bios is also updated with MS-Update-Prog.
The audio keys are working. (F6 / F7)
The F3 and F4 are calling a dialog (HP Hotkey Support), nothing else.
Anyone are able to help me? / Thanks for reading. (Do not burn. 🙂 )
