Abstract

A system and method for improved activation of a personal computer and/or other processing devices is provided. Power and security states are combined and further reduced to three activation states which may be operated by a single secure device. The system may include any number of activation states for operating the computer using only the single secure device. The secure access device handles both security and power management by authenticating physical access to the computer and the identity of the user. For this purpose, a device containing a biometric reader may be integrated with a smart card and the biometric identification used as an authentication code to secure the smartcard. The secure access device may be inserted into a locking mechanism used by the user to transition between activation states.

Claims

1. A system, comprising:

a computing system;

wherein the computing system comprises a security system and a power management system, the security system comprising two or more security states and the power management system comprising two or more power states, wherein the power states comprise off, standby, and on, wherein the standby power state further comprises sub-states hibernate, service, and sleep, and the security states comprise off, on, and standby, wherein the on security state further comprises sub-states login, logged in, and locked,

computer storage media including at least one memory storage device;

a device enabled to control the power management system and the security system of the computing system;

the device being enabled to accept a secure access device; and

wherein the device is configured to control the computing system transitioning from the on power state to the standby power state by causing the computing system to turn off a main monitor, spin down a hard drive, and shut off system fans and enter the service sub-state for a predetermined period to process any pending background tasks; and

when determining that the computing system has been in the service sub-state for the predetermined period and no pending background tasks to process, causing a sleep event to be generated and the computing system to transition from the service sub-state to the sleep sub-state.

2. The system of claim 1 wherein the secure access device comprises a biometric identification device.

3. The system of claim 1 wherein the secure access device comprises a smartcard device.

4. The system of claim 2 wherein the biometric identification device is integrated with a smartcard device.

5. The system of claim 1 wherein transitions between power states are enabled by events comprising:

a restart event causes a transition from off to on;

an open chassis event or a shut down event causes a transition from on to off;

a power loss event causes a transition from on to hibernate;

a standby event causes a transition from on to service;

a power restored event causes a transition from hibernate to service;

a hibernate event causes a transition from service to hibernate;

a sleep event causes a transition from service to sleep;

a wake up event causes a transition from sleep to service; and

a resume event causes a transition from each of hibernate, service and sleep to on.

6. The system of claim 1 wherein transitions between security states are enabled by events comprising:

a restart event causes a transition from off to login;

a shutdown event causes a transition from each of login, logged in, and locked to off; and

a resume event causes a transition from standby to one of logged in or locked.

7. A method of integrating and simultaneously managing power management and security management of a computing system, the computing system comprising a security system and a power management system, the security system comprising two or more security states and the power management system comprising two or more power states, the method comprising:

providing a single device enabled to control the power management system and enabled to control the security system,

the power management system having power states comprising off, standby, and on, wherein the standby power state further comprises sub-states hibernate, service, and sleep,

the security system having security states comprising off, on, and standby, wherein the on security state further comprises sub-states login, logged in, and locked, and

the device being enabled to accept a secure access device;

accepting input from the device, the device having accepted the secure access device;

selecting states for the security system and the power management system based upon state of the device, the secure access device, and one or more events;

a transition from the on power state to the standby power state causing the computing system to turn off a main monitor, spin down a hard drive, and shut off system fans and enter a service sub-state for a predetermined period to process any background tasks pending; and

when having been in the service sub-state for the predetermined period and no pending background tasks to process, generating a sleep event and causing a transition from the service sub-state to the sleep sub-state.

8. The method of claim 7 wherein the secure access device comprises a biometric identification device.

9. The method of claim 7 wherein the secure access device comprises a smartcard device.

10. The method of claim 8 wherein the biometric identification device is incorporated with a smartcard device.

11. The method of claim 7 further comprising:

a restart event causing a transition from power state off to on;

an open chassis event or a shut down event causing a transition from power state on to off;

a power loss event causing a transition from power state on to hibernate;

a standby event causing a transition from power state on to service;

a power restored event causing a transition from power state hibernate to service;

a hibernate event causing a transition from power state service to hibernate;

a sleep event causing a transition from power state service to sleep;

a wake up event causing a transition from power state sleep to service; and

a resume event causing a transition from each of power states hibernate, service and sleep to on.

12. The method of claim 7 further comprising:

a restart event causing a transition from security state off to login;

a shutdown event causing a transition from each of security states login, logged in, and locked to off; and

a resume event causing a transition from security state standby to one of logged in or locked.

13. A computer program product comprising instructions stored in one or more computer readable media to execute the method recited in claim 7.

14. The computer program product of claim 13 wherein the secure access device comprises a biometric identification device.

15. The computer program product of claim 13 wherein the secure access device comprises a smartcard device.

16. The computer program product of claim 13 wherein the method further comprises:

a restart event causing a transition from power state off to on;

an open chassis event or a shut down event causing a transition from power state on to off;

a power loss event causing a transition from power state on to hibernate;

a standby event causing a transition from power state on to service;

a power restored event causing a transition from power state hibernate to service;

a hibernate event causing a transition from power state service to hibernate;

a sleep event causing a transition from power state service to sleep;

a wake up event causing a transition from power state sleep to service; and

a resume event causing a transition from each of power states hibernate, service and sleep to on.

17. The computer program product of claim 13 wherein the method further comprises:

a restart event causing a transition from security state off to login;

a shutdown event causing a transition from each of security states login, logged in, and locked to off; and

a resume event causing a transition from security state standby to one of logged in or locked.
