In Ubuntu go to System -> Preferences -> Screensaver. Click on the Power button to set the power management options. Here you set the screen saver attributes. Select Properties, then choose the Screen Saver tab.

To set your computer’s Power Management options, in Windows you can right-click on the desktop, “Blank screen” as the most energy efficient screen saver.) To saveĮither turn off your display or set its power management options. They may even use moreĮlectricity if they’ve got color graphics moving all around. DOE definitions for Standby and Hibernate. The computer can “awake”įaster than from hibernate mode but uses some minimal power to enable Non-essential components are powered down. Standby means the computer still uses power but at a reduced level. The computer uses zero power during hibernation. Hibernate powers up faster than a regular boot. These recognize two distinct states: hibernate and standby. Manufacturer! There is no industry-standard meaning for these terms. How they work vary by operating system and by computer There’s lots of confusion between the terms standby, sleep, and hibernate.įor good reason. These are your computer’s power usage levels,įrom greatest power consumption to least:Ī heavily-used computer sucks more power than one at idle, while idling requires more power than standing by or hibernating. Measurements with your new voltmeter quickly expose a powerĬonsumption hierarchy. Remember that we’re excluding otherįactors like the energy used during manufacture, longevity (MTBF), I’ve made many assumptions here but the approach is valid. I can use this number to help me decide whether buying At 55 watts/hour the laptop consumes around 80.3 kWh perĪssuming 15 cents per kWh, that prices the desktop’s annual electricalīill at about $29.56 and the laptop’s at $12.05. At 135 watts/hour, the Dell desktop consumes roughly 197.1 We’ll again assume 4 hours of moderate use per day, or 1,460 hoursĪnnually. The MacBook clocks in at 55 to 58 watts for The Dell desktop and itsĭisplay together consume 104 to 162 watts during moderate use.

Say I want to replace a Dell OptiPlex GX260 Pentium 4 and its 17″ĭell LCD display from 2003 with an Apple MacBook Pro withġ5″ integral display from 2010. Let’s use the formula to compare laptop to desktop energy costs. (Here are example power specs for the iPad and iPhone.) From least to greatest energy consumed, the device type hierarchy is: If they meet your needs, consider moving to even more energy-stingy devices, Whether laptops last as long as desktops, how much energy goes into Only talking ongoing energy consumption here. I’ll show you a formula below so you canĮasily determine the energy cost savings you get with a laptop. If you’re buying a computer andĮlectricity, go with a laptop. This chart lists power consumption for displays alone.Ī laptop in use always uses less electricity than a desktop in use. View this power consumption chart to see how much electricity some typical systems use. Both figures include typical LCD displays. Watts while in use, while laptops often burn between 15 and 60 watts. Voltmeter!) Most desktop computer systems consume between 70 and 200 It’s tough to generalize about computer powerĬonsumption because it varies so widely. We’ll discuss the Standby, Sleep, and Hibernate states below.Ģ. Your computer can be in different “power modes.” When you’re not using it, your computer drops into a low power mode.
