Windows 8 Control Panel – System and Security – Power Options

August 6, 2012

How to Launch It

  • Open the traditional Control Panel through the Start Screen or using the Run Windows command “control”.
  • Select “Category” view for Control Panel.
  • Select “System and Security” category. This opens a new page containing the subcategories.
  • Select “Power Options”. This will launch the applet on the same control panel page.
Windows provides following 3 pre-configured power plans.
  • High Performance – This plan will not at all take energy consumption into consideration. The system will concentrate only on performance and speed. This may be an ideal plan for a gaming PC.
  • Balanced – The system keeps a balance between performance and energy consumption. It uses performance wherever required, like gaming, and will try to save energy in low-intensity applications.
  • Power saver – The system will do as much as it can to lower energy consumption, without giving much thought to the performance. This is an ideal plan for a battery-powered laptop.
You can select any of these plans if you don’t want to customize in detail.

Power Plan Settings

You can customize the settings of a power plan.   The customization is divided based on what power source your system is running on – AC power or battery. The settings provide four customizations for both the power sources.
  • Time duration after which the display should be dimmed.
  • Time duration after which the display should be turned off.
  • Time duration after which the computer should be put to sleep.
  • Adjust the screen brightness
For example, the display should be turned off after the system remains idle for 5 minutes, when running on battery, and 10 minutes, when running on AC power. Based on such customizations, you can also create your own power plan.

System Power Settings

These settings deal with any physical interactions like pushing a physical power button, or closing the lid, etc. They apply to the system, regardless of a power plan. Again, an action is carried out depending on the power source of the machine – battery or AC. The following 3 customizations are available.
  • Pressing the physical power button
  • Pressing the physical sleep button
  • Closing the lid
The following four actions are available to respond to any of the above 3 situations.
  • Put the computer to sleep
  • Hibernate the system
  • Shut down the system
  • Do nothing
For example, when lid is closed, then system should be put to sleep when running on battery, and nothing should be done when running on AC power. Besides that, you can specify whether the Power Menu of the Settings Charm should show the options of “Sleep” and “Hibernate”. Similarly, you can also specify whether the account menu on the Start Screen should show “Lock Screen” as an option.]]>
