Abstract
In current PC systems, there are a lot of open slots which allow an end‐user to extend the
system features, for example, graphics cards, SATA/USB storage cards, NIC cards, Type‐C cards,
etc. Most of the add‐on cards are not required to work during sleep, hibernate, or shutdown
states, but they will still consume the system power in those system states.
This invention is to provide a comprehensive solution, including hardware (HW) and software
(SW), to identify the device type (installed in an open‐slot), monitor power, and cut OFF the
unnecessary standby power to reduce the system power consumption.
