Abstract
Certain embodiments of an extreme power down mode for extreme power savings when no network presence is detected may comprise disabling at least one device driver for at least one hardware device in a network adapter chip. The device driver may be disabled prior to disabling the hardware device upon starting a power reduction mode for the network adapter chip. The device driver for the hardware device on the network adapter chip may be enabled after enabling the hardware device upon ending a power reduction mode for the network adapter chip. The hardware device may be disabled by reducing power to it. Similarly, power may be provided to the hardware device to enable it. The network adapter chip may be reset to enable the hardware device upon providing power to the hardware device so that the hardware device may be at a known state.
