The hardware ID is located under [Standard. The driver will be unloaded as soon as the system detects that there are no more devices connected to the computer that are to be handled by that driver.
Anyhow, speaking of power management, it’s time to shut off all electronic devices, raise my seatback to its most upright position, and stow away my tray table.
