Desktop Power Management

What is Power Management?

Power management is a process whereby the computer turns off internal devices and enters a low power sleep state when it is not in use. Generally, the monitor and hard disk are turned off and the computer only consumes enough power to keep information in memory. This allows the computer to quickly return back to the state you left it without any data loss.

How much energy/costs will power management save?

It really depends upon the configuration of your computer, how often you use the computer, what the computer is used for, and cost per kilowatt hour. There are also other hidden costs such as cooling due to the heat output of the PC.

 

On average, a PC and flat screen monitor use 65 watts/hour and 35 watts/hour respectively when sitting idle. In a sleep state they will consume 2-10 watts/hour together; this saves about 90 watts/hours. If we assume that the computer is only used 8 hours a day, we can calculate an estimated cost savings:

 

16 Hours (idle)    365 Days   90 Watts    1 Kilowatt        $0.08*
--------------------- X ------------- X ------------- X ----------------  X  ------------- = $42 per year
1 Day                1 Year       1 Hour        1000 Watts     Killowatt

* Department of Energy Average cost per Kilowatt Hours for commercial consumers in North Carolina in 2010

When will my computer “go to sleep”?

Power management will send to workstation into sleep states based upon user activity. When the computer detects no mouse or keyboard activity, it begins an idle countdown timer. When the timer runs out, the indicated power setting takes effect. Whenever the user interacts with the workstation, the timer is reset and process begins again.

Power Setting                    Idle Time Value
------------------------------         -----------------------
Monitor Power Off              20 Minutes
Hard Disk Power Off          0 Minutes*
Enter Standby Mode         30 Minutes

*The power required by the hard disk represents a very small percentage of the power consumption of a PC. Excessive disk power on/off cycles can greatly reduce the life of the hard disk.

Will the computer go to sleep while watching a video or listening to audio?

It depends upon the software you are using. Software developers are responsible for writing their code to reset the idle timer at regular intervals to prevent the workstation from entering a sleep state. Windows Media Player will handle this idle timer when listening to music and watching videos.

 Are there exceptions to this power management policy?

There are exceptions in cases where power management interferes with the primary function of a workstation. Common exceptions include kiosks and digital signage devices.

For any questions, or inquiries, please do not hesitate to contact the Help Desk.
We strongly advise students and faculty/staff to inform us should they notice any machine(s) that are not going into powering saving mode.
