• Windows 7 uses power plans to control how your computer implements power management. There are three default power plans. Some of the details of each default power plan for a laptop computer are listed in Table 3-3. In addition, you can create your own power plans. The options available to you when creating or modifying a power plan vary depending on the capabilities of your computer hardware. For example, settings for running on battery power only apply to portable computers with a battery.
