There have been several attempts to add support for this in the past. The last one being: https://lore.kernel.org/platform-driver-x86/20220922182424.934340-1-lkml@xxxxxxxxx/ Note that in this case this also required some vender specific poking in toshiba_acpi to get things to work. I see that the HP Compaq 8710p is about the same vintage as the Toshiba Z830 on which the last attempt to do something about the quick start buttons was done. So this might very well explain the missing button issue. Regards, Hans
