Patent ID: 7689842

Claim:
A method of providing a simulated off condition in a computing device via a set of software extensions, said method comprising: providing a device driver for each component to be managed; providing a policy driver to coordinate information from device drivers to determine a power state of said computing device; receiving a signal to change the power state of said computing device; instructing system components to change their respective power states in accordance with said signal; if said signal is representative of a request to enter a low power state, reducing power consumption of said system components such that said computing device enters a simulated off state, wherein said computing device remains at a fully on and said system components remain enabled to run applications when the computing device is in the simulated off condition; if said signal is representative to a request to enter a fully on power state, returning said system components to said fully on power state; locking human interface devices by discarding inputs; and detecting a predefined input sequence, said predefined sequence being said signal.
