feature. This option defines how the BIOS, in
the absence of a USB-aware operating system,

enabled during POST (Power On Self Test).
Note: You cannot boot any type of USB device
(floppy, hard drive, or memory key) when this
option is off.

while the notebook is turned off.

system from Standby or to disable the USB wake
