Myth 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 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 on
Fact: 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 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 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.

Power Management
Benefits
•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

Caution
In the near-term we advise that you enable MONITOR
energy savings but DO NOT enable COMPUTER energy
saving actions if you rely on the following activities which
require the computer to be on:
 Scheduled backup services using the enterprise backup
solution, Tivoli Storage Manager (TSM)
Remote access to files and desktop
Remote system administration (check with your
departmental IT support)

From lab to campus
Opportunities for Collaboration
• Data on IT asset inventory - desktops, laptops, servers, printers
• Disseminating educational materials
• Making use of potential DITR training
• Procuring efficient IT equipment
• Walking the IT energy talk in your areas
• Planning power and cooling needs
• MIT vehicle fleet and fuel choices
