Power management is a feature that efficiently manages and optimizes the power consumption of computer hardware thereby saving money and energy. Green Computing refers to the efficient use of computer resources. Some of the green computing practices include, Server Virtualization, Power Management, Secured Network to reduce eWaste, Using Recycled Materials, and so on. Though the ultimate goal is to save the planet and the resources for our future generations, let us limit ourselves with the Power Management here.
Power management features and capabilities in Desktop Central
The PCI Power Management registers would control the internal state of a device, such as internal clocks and power planes. ASL would control the external state, such as external clocks and power planes, or in the case of video controllers, ASL would control the video backlights. Note that ASL and PCI-PM can only be combined on motherboard devices. If you need to see the Power Management Tab (hidden) in device manager you have to create a specific key and set value to 0 Open RegEdit and move to HKEYLOCALMACHINE SYSTEM CurrentControlSet Control Power If it's not created yet, you have to create a new DWORD key named CsEnabled and set the value to 0.
How to See a Process’s Power Usage Details. First, open the Task Manager by right-clicking your taskbar and selecting “Task Manager,” or by pressing Ctrl+Shift+Esc. If you don’t see the full Task Manager pane, click “More Details” at the bottom. Activate Power Management on Your Computer Click on your operating system below and follow the instructions to configure power management features on your computer. Note that your monitor may already enter a low-power sleep mode when the computer is inactive, but the computer itself may not. The boss of the ACPI based power management is the power management component of the kernel. The kernel power manager handles the devices' power policy, calculates and commands the required.
Desktop Central comes with a power management tool that helps to standardize the power settings in all the computers of the network at once. It provides the following PC power management options for Windows, Mac and Linux:
- Enables creating, modifying, and applying power schemes to 1000s of computers across all branches at once using the Power Management Configuration.
- Supports creating multiple schemes for various departments/divisions.
- Create power schemes with advanced options for Laptops.
- Hibernate or Standby an idle computer using the Remote Shutdown Tool
- Shutdown computers from remote using the Remote Shutdown Tool. The shutdown operation can be scheduled to happen at defined interval.
- Disable screen savers using the Registry Configuration and hide the Screen Saver tab from the users using the Security Policy Configuration so that they may not be able to activate it again.
Create and apply power schemes
The Power Management Configuration in Desktop Central allows you to create multiple power schemes that can be deployed to multiple computers. A variety of advanced power management settings can be applied based on the desired power saving scheme. The advanced options allows you to specify what has to be done when the laptop is closed or when the power button is pressed.
Turn-off screen savers
The screensavers were originally designed to save the CRT monitors from getting damaged by automatically changing the images on the screen during periods of user inactivity. With the advent of LCD monitors and technology improvements in mordern CRT monitors, screensavers are no longer required to protect monitors from phosphor burn-in. A graphically more intensive screensaver will require more power than the normal screen. While turing off the monitor from the power schemes will help you save power irrespective of whether screesaver is enabled or not, you can use the Desktop Central Registry Configuration to turn off the screensavers in older models that do not support power schemes.
Shutdown inactive computers
Considering a normal working hours of 40 hrs/week, shutting down the computers during non-office hours will alone let you save a whopping 76% on your energy consumption. Desktop Central allows you to schedule remote shutdown tasks that can be scheduled to run on all weekdays. This helps you to shutdown all the computers during non-working hours. You can create multiple tasks to shutdown groups of computers at different times based on the employee working hours.
Granular control
Desktop Central gives you a complete control on the target computers to which the configuration has to be deployed. You can create a custom group of users/computers and apply different power schemes to have an efficient power management system in place. You can also exclude certain computers based on their OS and types from the selected targets.
What is power management?
Power management refers to a set of sustainable practices to efficiently manage the power consumption of computer hardware. In computer power management, these practices may include turning off monitors when not in use, disabling screensavers, inducing a computer into sleep mode after a period of inactivity etc. When it comes to an enterprise with multiple end users, power management in computers is necessary to keep power consumption costs down and be more resourceful.
Why is power management important?
- Optimize overall power consumption.
- Save cost by means of conserving energy.
- Extending the lifetime of laptops and computers operating in the organization.
- Track and monitor power usage by computers and users.
- Lower carbon footprint.
How it started?
The launch of the Energy Star program back in 1992 was one of the first manifestations of the green computing movement. Started by the US Environmental Protection Agency, it served as a kind of voluntary label awarded to the products that minimizes the power usage. Energy Star applied to Computer Monitors, Television Sets, Air Conditioners, Refrigerators, etc.
How much energy does a computer use?
A typical desktop computer comprises of CPU and a monitor. A computer running Intel P4, 2.4 GHz processor consumes 64.6 Watt per hour. Add another 50-100 Watt for the monitor. While the CPU consumes much litter energy when idle, the monitors on the other hand consume the same energy even when the computer is idle.
Watch directv on att phone. Let us do the math to calculate the average power consumption of a computer:

- Assuming that a 150 W computer is put to use day and night every day, the direct annual cost on electricity is $150 (at $0.1153/KWh)
- In contrast, if the same computer is used only during the normal working hours (40 hours a week), the cost would be $36
- The saving is $114 which is a stunning 76%
This is just for a single computer. As the number of computers increases, the saving on the electricity cost is huge. Just to give an example, for 2000 computers, the annual saving is $22,800.
Also, EPA estimates that the computers are active only 58% of time during working hours. The rest are used in non-computer activities such as phone calls, meetings, lunch, and refreshments. This idle time can be used to save additional power by adopting stringent power schemes to desktops.
What are power management techniques that can be adopted to save power?
Power management software typically list the following power management techniques that enterprises can adopt:
- Define appropriate power schemes to computers.
- Turn off screen savers.
- Shutting down the systems during non-office hours.
Conclusion
Whether the intentions are to save the planet or money, enterprises that adopt these energy saving techniques will be benefited. Desktop Central in addition to desktop power management offers various features like Software Deployment, Asset Management, Patch Management, Remote Control, Active Directory Reports, User Logon Reports, and Windows System Tools.
