SUMMARY
The energy management features in
your "Windows.." computer let you do
partial power-downs of your computer
so that you can re-start exactly where
you left off in your open and
minimized Web browser windows and
in all open and minimized windows of
your software programs.

BASIC CONCEPTS OF PC POWER
MANAGEMENT
• The energy management features in
your "Windows.." computer let you
do partial power-downs of your
computer so that you can re-start
exactly where you left off in your
open and minimized Web browser
windows and in all open and
minimized windows of your software
programs.

BASIC CONCEPTS OF PC POWER
MANAGEMENT (continued)
• These energy management
features can dramatically reduce
the delays that are caused by
multi-tasking between your
computer and non-computer
activities.

SLEEP
"Sleep" shuts off many parts of
your computer but it keeps
your RAM and other parts of
your motherboard powered up
so that you can start up where
you left off by clicking a mouse
button or a keyboard key.

SLEEP (continued)
If your computer loses
power during "sleep", your
minimized and open
windows are lost from
RAM and the computer
cannot restore them for
you.

HYBRID SLEEP:
![Page 12: ENERGY MANAGEMENT FOR YOUR WINDOWS.. COMPUTER: …1 energy management for your "windows.." computer: a comparision of sleep, hybrid sleep, and hibernate](https://reader034.vdocuments.us/reader034/viewer/2022042302/5ecd8c34e634cb40971615fb/html5/thumbnails/12.jpg)

HYBRID SLEEP
• "Hybrid sleep" does everything
that "sleep" does but it also
stores all open and minimized
windows in a "hyberfil.sys" file.
![Page 13: ENERGY MANAGEMENT FOR YOUR WINDOWS.. COMPUTER: …1 energy management for your "windows.." computer: a comparision of sleep, hybrid sleep, and hibernate](https://reader034.vdocuments.us/reader034/viewer/2022042302/5ecd8c34e634cb40971615fb/html5/thumbnails/13.jpg)
13
HYBRID SLEEP (continued)
• If your computer loses power
during "hybrid sleep", when
you restart the computer, it will
use the "hyberfil.sys" to
restore all minimized and open
windows so that you can start
where you left off.

HIBERNATE:
![Page 15: ENERGY MANAGEMENT FOR YOUR WINDOWS.. COMPUTER: …1 energy management for your "windows.." computer: a comparision of sleep, hybrid sleep, and hibernate](https://reader034.vdocuments.us/reader034/viewer/2022042302/5ecd8c34e634cb40971615fb/html5/thumbnails/15.jpg)
15
HIBERNATE
• "Hibernate" shuts off all
power to your computer
after it saves all minimized
and open windows to a
"hyberfil.sys" file.
![Page 16: ENERGY MANAGEMENT FOR YOUR WINDOWS.. COMPUTER: …1 energy management for your "windows.." computer: a comparision of sleep, hybrid sleep, and hibernate](https://reader034.vdocuments.us/reader034/viewer/2022042302/5ecd8c34e634cb40971615fb/html5/thumbnails/16.jpg)
16
HYBERNATE (continued)
• When you power up your
computer again, it reads
the "hyberfil.sys" file to
restore all minimized and
open windows so that you
can start where you left off.

SOME PROGRAMS
ARE "SLEEP
PROOF":

SOME PROGRAMS ARE "SLEEP PROOF"
• Some alarm clock programs
can wake up your computer
from "sleep" but they cannot
wake up a computer from
"hybrid sleep" or "hibernate".

SOME PROGRAMS ARE "SLEEP PROOF"
(continued)
• One example of a sleep-
proof alarm clock program
is "Free Alarm Clock",

SET UP
"BRIGHTNESS
PROFILES" FOR
YOUR MONITOR(S):
![Page 21: ENERGY MANAGEMENT FOR YOUR WINDOWS.. COMPUTER: …1 energy management for your "windows.." computer: a comparision of sleep, hybrid sleep, and hibernate](https://reader034.vdocuments.us/reader034/viewer/2022042302/5ecd8c34e634cb40971615fb/html5/thumbnails/21.jpg)
21
SET UP BRIGHTNESS PROFILES FOR
YOUR MONITOR(S)
• To save even more electricity,
set up various brightness
profiles for your computer's
monitor(s) so that you
computer monitor is not
overly bright for a given
amount of ambiant light.
