Abstract

The present invention relates to a computer system and method having a power management state in which communication network transactions take priority over any power management events in an effort to ensure that communication network transactions are not adversely affected by a power management system.

Claims

1. A computer system comprising communication means to exchange data with a communication network and a power management system for controlling the power consumption of the computer system;

the power management system comprising means to maintain a current power consumption of the communication means if a data exchange, via the communication means, with the communication network is pending and means to at least reduce power consumption of the communication means if such a data exchange is not pending.

6. A computer system as claimed in claim 1, comprising a power supply for supplying power to the communication means and in which the power management system comprises means to control the power supply to control the power supplied to the communication means.

14. A computer program element comprising computer readable code means for implementing a system or method as claimed in claim 1.

15. A computer program product comprising a computer readable storage medium having stored thereon a computer program element as claimed in claim 14.

2. A computer system comprising a communication means for exchanging data with a communication network and a power management system to maintain the communication means in an operable state to allow a data exchange with the communication network if such a data exchange is pending and to at least reduce the power consumption of the communication means if a data exchange is not pending.

3. A computer system as claimed in claim 2 in which the power management system comprises means to determine that a data exchange is in progress and means operable to maintain the communication means in the operable state in response to that determination to allow the data exchange to be completed.

4. A computer system as claimed in claim 3 in which the power management system comprises means to determine that a data exchange is planned for a predetermined time and means to maintain the communication means in the operable state in response to that determination to allow the planned data exchange to be at least started.

5. A computer system as claimed in claim 4 in which the means to maintain the communication means in the operable state in response to that determination comprises means to allow the planned data exchange to be completed.

7. A computer system comprising communication means to exchange data with a communication network and a power management system comprising means, responsive to a command to change a current power consumption state of the computer system to a different power consumption state, to maintain the communication means in an operable state to support a data exchange with the communication network if such a data exchange is pending and means to at least reduce the power consumption to the communication means if such a data exchange is not pending.

8. A method of operating a computer system;

the method comprising the steps of controlling the power consumption of the computer system by maintaining a current power consumption of a communication means for exchanging data with a communication network if a data exchange, via the communication means, with the communication network is pending and reducing the power consumption of the communication means if such a data exchange is not pending.

13. A method as claimed in claim 8 further comprising the steps supplying power, via a power supply, to the communication means and controlling the power supply to control the power supplied to the communication means.

9. A method as claimed in claim 9 further comprising the steps of exchanging data with a communication network and maintaining the communication means in an operable state to allow a data exchange with the communication network if such a data exchange is pending and reducing the power consumption of the communication means if a data exchange is not pending.

10. A method as claimed in claim 9 further comprising the step of determining that a data exchange is in progress and maintaining the communication means in the operable state in response to that determination to allow the data exchange to be completed.

11. A method as claimed in claim 10 further comprising the steps of determining that a data exchange is planned for a predetermined time and maintaining the communication means in the operable state in response to that determination to allow the planned data exchange to be at least started.

12. A method as claimed in claim 11 further comprising the steps of maintaining the communication means in the operable state in response to that determination to allow the planned data exchange to be completed.
