Method and system for forcing one or more power states on a display

1. A method for forcing one or more power states on a display, comprising:

receiving ( 200 ) a power management electronic signal;

receiving a lock up signal indicating whether an operating system has locked up;

executing control logic ( 210 ) in a computer without use of the operating system to determine a desired level of the power management electronic signal based on the lock up signal;

setting ( 220 ) the power management electronic signal to the desired level; and

sending ( 230 ) the power management electronic signal at the desired level to a monitor.

2. The method as defined in claim 1 , wherein the power management electronic signal comprises at least one of a VSYNC and an HSYNC electronic signal.

3. The method as defined in claim 1 , wherein the power management electronic signal comprises an HDMI electronic signal.

4. The method as defined in claim 1 , further comprising sending the power management electronic signal at the desired level to a plurality of monitors.

5. The method as defined in claim 4 , further comprising selecting a number of monitors to which to send the power management electronic signal at the desired level based on a criterion.

6. The method as defined in claim 5 , wherein the criterion is a level of power shortage.

7. A management controller for forcing one or more power states on a display, comprising:

a computer ( 110 ) configured to receive a power management electronic signal;

the computer configured to receive a control signal indicating whether a power failure has occurred;

the computer ( 110 ) comprising control logic to operate without use of an operating system to determine a desired level of the power management electronic signal based on the control signal and to set the power management electronic signal to the desired level; and

the computer ( 110 ) configured to send the power management so electronic signal at the desired level to a monitor ( 120 ).

8. The system as defined in claim 7 , wherein the computer is further configured to send the power management electronic signal at the desired level to a plurality of monitors.

9. The system as defined in claim 8 , wherein the computer is further configured to select a number of monitors to which to send the power management electronic signal at the desired level based on a criterion.

10. The system as defined in claim 9 , wherein the criterion is a level of power shortage.

11. The system as defined in claim 7 , wherein the power management electronic signal comprises at least one of a VSYNC and an HSYNC electronic signal.

12. A non-transitory computer-readable storage medium encoded with instructions executable by a processing unit of a computing device, the storage medium comprising instructions to:

receive a power management electronic signal;

receive an external control signal from a network;

determine a privilege level for the control signal;

determine, without use of an operating system, a desired level of the power management electronic signal based on the external control signal if the privilege level is at or above a predetermined level; and

send the power management electronic signal at the desired level to a monitor.

13. The storage medium of claim 12 , further comprising instructions to:

set the power management electronic signal to the desired level.

14. The storage medium of claim 12 , wherein the power management electronic signal comprises at least one of a VSYNC and an HSYNC electronic signal.

15. The storage medium of claim 12 , wherein the power management electronic signal comprises an HDMI electronic signal.

16. The storage medium of claim 12 , further comprising instructions to:

select a number of monitors to which to send the power management electronic signal at the desired level based on a level of power shortage.

17. The storage medium of claim 16 , wherein the instructions to send comprise instructions to:

send the power management electronic signal at the desired level to a plurality of monitors, wherein the plurality of monitors has the selected number of monitors.
