Power Management
A computer is electricity-consuming. To keep this consumption as low as possible, make the best use of
your operating system's power management parameters, according to your needs. You can define for
instance that your computer will go into sleep mode after 10 minutes unused. See

"Managing System Power (Windows Vista
In addition, here are some other helpful power management tips:
•
Limit screen-saver use. A screen saver does not save energy. In fact, more often than not, a screen saver
not only will draw power for the monitor, but also will keep the CPU from shutting down. Instead, set
your computer to turn off the monitor first, then go into standby mode after a longer period of
inactivity.
•
Keeping your Virtual Private Network (VPN) connected may limit your system's ability to enter
standby mode. We recommend you disconnect your VPN when not actively using your corporate
network.
•
Many popular computer games and other third party software packages that run in the background will
not allow the computer to go to sleep – even if they are paused or the active window is minimized.
•
Some web sites or pages that have active banners and or animated advertisements will not allow the
computer to sleep on its own and must be closed, or the computer put manually into a sleep state.
•
Advanced users may wish to establish multiple power schemes to address different usage models. For
example, you can create a power scheme for playing music CDs that shuts off your hard drive and
monitor immediately, but never puts your system into standby mode.
•
To maximize the battery life of your notebook computer, consider setting even more aggressive
monitor, hard drive and standby/sleep settings for battery mode.
Turning Your Computer Off
Turn your computer off if you will not use it for several hours. If you need to keep it on, for example when
you are burning a CD, do not forget to turn off the peripherals (screen, speakers, printer...).
Shutting Your System Down
As some LEDs stay on even when the system is shut down, it might be a good idea to power it down
completely when you don't use it for a long period, for nights or week-ends for example.
