There are two ways to customize Windows 7 power options beyond the available power management plans. Either customize an existing power management plan or create your own custom plan. To help save power, Windows 7 offers three types of sleep modes for your computer.
Edit any existing Windows 7 power management plan by pressing Change Plan Settings beside the plan of your choice. A power options window appears with power settings for most of the hardware on your computer, such as hard drive, wireless adapter and USB. There are also settings for adding a password to wake your system up after your power management plan goes into effect.
If you want to change any power options that are not listed in a specific plan, press the Change Settings That Are Currently Unavailable. If you want to return a power management plan to its original settings, press the Restore Plan Defaults button.
The second way to customize Windows 7 power options is to create your own plan. Press the Create a Power Plan link on the left side of the Windows 7 Power Options control panel. Select a name for your power plan. The same power options window appears as when you edit existing plans.
If you use multiple power management plans, name your plans based on situation or location. For instance, if you want to use your Windows 7 laptop on the go, a more aggressive power plan works best to save battery life. You could name this plan “Travel" or “On the Go." At home, you may not want your screen to turn off until an hour of inactivity has passed. This plan may be called “Home."
If you're uncertain of what options you should choose, get a power usage report from your Windows 7 computer to determine how much power your currently use. This will help you determine which options to choose to reduce your power consumption.
