Myth or FactMyth or Fact

Myth: Use screen savers to save your screen

Fact: Screen savers were originally developed to prevent the permanent etching of a pattern on older monochrome monitor. The same protection occurs when you place the monitor in a low power “sleep” mode. Avoiding the use of screensavers on LCD and CRT displays can save power usage while away from your computer by 30-75 watts.

Myth or FactMyth or Fact

Myth: Computers have a shorter life when power cycled on and off Fact: Hard disks in PC’s older than 10 years did not automatically park their heads when shut off, leading to disk damage from frequent on/off power cycling. Newer PC’s are designed to handle 40,000 on/off cycles, a number unlikely to be reached during an MIT computer’s typical four-to-six-year life span. Myth: Turning your computer off uses more energy than leaving it onFact: The power surge when a computer is turned on lasts a few seconds and is insignificant compared to the energy used to power it when idle.

Power Management Desktop/Laptop

Power Management Desktop/Laptop

Power usage can be reduced by 15 -65 watts if you..

•Choose Standby setting for inactivity of 1 hour. This will allow you to attend most meetings. Time to wake up is less than 30 seconds, typically only 8-10 seconds

•Set Hibernate mode for laptops for 1- 3 hours of inactivity, while traveling to gain extra battery life.

In the near-term we advise that you DO NOT enable these energy saving actions if

you rely on the following activities that require the computer to be on:

•Scheduled backup service over the network using enterprise backup solution, Tivoli Storage Manager (TSM)

•Remote access to files and desktop

•Remote system administration (check with your departmental IT support)

IS&T is exploring tools and solutions that will allow us to harness energy savings

from all the computers, without impacting function and service

Power Management Monitors

Power Management Monitors

Power usage can be reduced by 30-60 watts if you..

•Avoid using screen saver

• Choose Turn off/Sleep setting for inactivity of 10 minutes. This will allow you to attend to short tasks like phone calls. Time to wake up is 3-5 seconds.

•Energy Savings

•Reduced heat dissipation leading to reduced cooling energy

•Extra battery time for laptops

•Lower noise from reduced use of power supply and cooling fans
