Power Managment

 

Reducing your computer's power consumption can be a surprisingly easy way to save money, do a little something for the planet, and extend your equipment's life.

Power Manager Provides 4 simple approaches to reduce your computer power consumption by up to 50% !
1-Controlling monitor brightness and unloading and disabling hardwares

2-auto power off the computer in special conditions defined by the user (Download or Backup Complete, Process end, specific time or based on the condition of windows or running programs)

3-turn off the computer on a specific time & auto turn off monitor and computer sleep

4-provide the ability to change the computer power state immediately ...

Reducing system power consumption will extend battery life, reduce system temperature and (on some models) reduce system fan noise. Power consumption can be greatly improved from a stock distribution configuration to a fine tuned system. The general rules are :

Unload drivers for unused devices (ie. USB 1.1, Yenta/PCMCIA, Wireless, IRDA, Bluetooth, ...)
Reduce polling on devices (drives, USB subsystem, nvram, use SATA AN, ...)
Reduce hard drive activity
Reduce LCD brightness to the minimum you can stand
Reduce CPU wakeups, so it can stay longer in deep power saving c-states
Make use of every hardware devices availables power saving features (AHCI ALPM, USB autosuspend, Alsa and Wireless powersaving modes, HPET timers, ...)




Computers occupy a small but growing percentage of annual U.S. electricity consumption (see References 1). Hard drives, processors, video cards, monitors and other computer components all consume power, and all can be custom-selected with an eye toward efficiency. Efficient hardware combined with good power management can reduce the amount of energy a system needs. Automated software can also help reduce power usage when your computer is idle.

One of the most fundamental steps to take when trying to green your IT Department is to perform an energy consumption analysis.  You will first have to create a baseline in order to estimate your annual energy use.  This is easy to do by taking an inventory of the energy consumption of your current IT hardware such as desktop PCs, monitors, laptops, servers and equipment, and networked peripherals such as printers and scanners.

According to a study conducted in 2001 for the US Department of Energy, IT equipment accounts for 3% of total US electricity consumption.  One easy way to green your IT Department is to implement PC power management software.  According to a report conducted by the Alliance To Save Energy and 1E entitled The PC Energy Report 2007, power management software can reduce a PC’s power consumption by as much as 80 percent, saving companies from $25-$75 per desktop PC.  A mid-sized company will waste more than $165,000 a year in electricity costs for computers that are left on overnight.  By simply turning these computers off, companies can keep more than 1300 tons of CO2 out of the atmosphere.


Power management software simplifies the process of implementing power management policies across a large network of PCs.  It enables the company to take control over the entire network, monitoring how long PCs are allowed to stay on while inactive, at what time PCs will be shut down at the end of a shift, and at what time PCs need to power up in order to install updates.  This enables companies to implement power-saving strategies for little cost and with little effort and maintenance from the IT Department.

There are many network based power management software solutions available:  Surveyor, Edison, EZ GPO, Night Watchman, BigFix, Faronics Power Save and Apple Remote Desktop.  None of these software packages costs more than $20 per license with the exception of Apple Remote Desktop (which is $499 for unlimited licenses), and two are even free (Edison and EZ GPO).  According to MG&E, there are four criteria for choosing the power management software that fits the needs of your organization best:  the software should show your energy savings, it should be flexible enough to allow different settings for different users, it should be capable of identifying the hardware and operating system used at each workstation, and it should be able to shut computers down to ensure that PCs are not left on overnight or over the weekend.


Power management software provides a simple and effective network-level of control over PC power management settings, decreasing your energy costs while also decreasing the amount of CO2 released into the atmosphere.  According to an article on businessweek.com, energy costs comprise nearly 10 percent of a corporate technology budget but could rise to as much as 50 percent in the next few years.  In a time where technical efficiency is critical to the bottom line, reducing energy consumption is a practice that is no longer optional. Power management can only enhance inventory management in helping to determine the efficiencies of equipment and resources.
