Power Management in Windows Vista
Power management is controlled in the Power Options window. To get to the power management controls from the Control Panel Home, choose System and Maintenance and then choose Power Options. From the Control Panel Classic view, open the Power Options icon. The Power Options window, as shown in the following figure, opens.
The Power Options window features three preset plans for managing the power in your PC, as listed in the following table. Each plan differs mainly in how two timeout values are set: for the display and for putting the computer into Sleep mode.
|Plan Name||Turn Off Display After||Put PC to Sleep After|
|Balanced||1 hour||2 hours|
|Power Saver||20 minutes||1 hour|
|High Performance||1 hour||Never|
To choose a plan, click the radio button next to the plan name. Close the Power Options window and you’re done. You can also customize any plan or create your own plan.
