Some computers do not let Windows fully control power management. If you find that changing the Standby, Monitor, or Hard Drive timeout values in the Power Control have no effect, your computer's own power management settings are overriding Windows' settings. Open your computer's power management Setup program and disable any Standby, Suspend, Monitor, or Hard Drive timeout values. After you do this, you should be able to control these settings from the Windows Power Management control panel. |
