Compared to previous versions of Microsoft Windows, Windows Vista offers
significantly expanded power management for portable computers. Features
that Toshiba had previously included in the Toshiba Power Saver utility are
now an integral part of the Windows Vista operating system.
This document describes the Windows Vista Power Options system of power
plans -- including how to edit them and how to uncover some of their very
useful advanced features, including how to reduce fan noise, what happens
when you close the display lid, and what happens when the battery reaches a
critically low level.
Resolution (detailed):
Selecting a power plan
To open the Windows Vista Power Options, click the Windows Start button,
then click Control Panel, Mobile PC and finally Power Options. A window
similar to the one below will appear.
http://aps2.toshiba-tro.de/kb0/HTD84026Q0000R0150421.jpg
Another way to access Power Options is to right-click the Power icon in the
Notification Area of the Task Bar, and then click Power Options.
The three standard Windows Vista power plans are shown in the screen shot
above:
* Balanced � Good performance balanced with good battery life
(moderate power consumption).
* Power saver � Battery life prioritized over performance (low
power consumption).
* High performance � Performance prioritized over battery life
(high power consumption).
Click the corresponding 'radio button' to select one of these power plans.
Power plans can also be selected by clicking the Power icon in the
Notification Area of the Task Bar.
In the left pane of the window shown above are direct links to commonly
useful settings, including what happens when the computer's display lid is
closed. These settings and others are covered in detail in the remaining
sections of this document.
Editing a power plan
To edit one of the default power plans listed above, click the Change plan
settings link for that plan. The Edit Plan Settings window will appear,
looking similar to the window below (for the Balanced power plan). You can
change any of the power setting in this window, or simply review them
without making changes.
http://aps2.toshiba-tro.de/kb0/HTD84026Q0000R0150422.jpg
>From several settings that comprise the power plan, only three are offered
in the window above. Many more settings are accessible via the Change
advanced power settings link.
Power plan settings occur in pairs, as in the window above, consisting of an
On battery setting and a Plugged in setting. This provides great flexibility
and allows you easily to establish exceptions to a given plan.
In the Balanced plan shown above, for example, you could maximize the
display brightness setting when running from the computer's battery, as
well as when the computer is plugged in to its AC adapter -- even though
the overall character of the plan remains balanced power consumption /
performance.
Advanced' power settings
>From the window shown above click Change advanced power settings which will
open a window similar to the one shown below.
http://aps2.toshiba-tro.de/kb0/HTD84026Q0000R0150423.jpg
Click the plus / minus indicators to expand and contract the entries in the
list above (two have been expanded already). To change a setting that is
grayed out, click Change settings that are currently unavailable.
Most of the advanced settings are described in the following list. As noted
above, the settings are listed as pairs, consisting of an On battery setting
and a Plugged in setting. Many settings can also be disabled, by selecting
�Never� (for example), instead of a time value.
These settings may vary over time, and new ones may appear, as newer
versions of Vista are released and pre-installed by Toshiba, and as Service
Packs for Vista are installed.
Additional settings �> Require a password on wake up
Determines whether or not you must enter your Windows password when the
computer wakes up from Sleep mode.
TOSHIBA Power Saver Settings V8.01.02�> Cooling Method
Specifies a CPU cooling method for either maximum CPU performance, or better
battery life with reduced CPU performance. If the sound of the CPU fan seems
too loud, a setting that optimizes battery life will also cause the CPU
fan to turn on less frequently.
Hard Disk �> Turn off Hard Disk After
Specifies how long -- after the most recent access -- before the hard disk
drive turnes off. Setting a lower timeout value will save more power. Once
the hard disk has turned off, there will be a slight delay with the next
access, as it 'spins up' to full rotational speed. Software that runs
automatically 'in the background' (search indexing, for example) may prevent
the drive from turning off, by accessing it at frequent intervals.
Wireless Adapter Settings �> Power Saving Mode
There are four power saving / performance settings. If your Wi-Fi connection
is unstable or slow, try selecting a higher-performance setting.
Sleep �> Sleep after
Specifies the number of minutes of inactivity (no usage of mouse or
keyboard) before the computer drops into Sleep mode. A short timeout
interval can save lots of power if you frequently stop using the computer,
without turning it off. Sleep mode preserves the state of open programs and
documents- it continues refreshing the computer's memory, while turning
off the screen, the hard disk drive, and most of the other computer
components. When the computer comes out of Sleep mode, the programs and
documents re-appear, just as they were when the computer entered Sleep mode.
Waking up the computer from Sleep mode is much faster than starting the
computer, starting the operating system, launching programs, and opening
documents.
Save open documents frequently to protect them from loss of battery charge
during Sleep mode. Sleep mode consumes some power from the battery, but less
than the normal On state. If the computer is in Sleep mode while being
powered from the battery, and the battery charge runs low, the computer will
turn completely Off, and will lose the open programs and documents in
memory. In this case, any changes to documents that are not saved yet disk
will be lost.
Sleep �> Allow hybrid sleep
Instructs Windows to use Hybrid Sleep mode, whenever Sleep mode is
activated. Hybrid Sleep mode not only saves the state of open programs and
documents in the computer's memory, it also saves their state to the hard
disk drive (as with Hibernation mode). Hybrid Sleep offers an additional
measure of convenience. If the computer's battery becomes fully discharged
while the computer is in Hybrid Sleep mode, the saved state in the
computer's memory will be lost, but Windows will be able to retrieve the
saved state from the hard disk drive -- though somewhat more slowly.
Be sure to save your documents and other files frequently as you work on
them, to create permanent copies of them on the computer's hard disk drive.
Saving the state of documents with Sleep, Hybrid Sleep and Hibernation modes
does not create permanent copies of them; it is just a way to save power as
you pause in your work, and then quickly pick up where you left off.
Sleep �> Hibernate after
Specifies the number of minutes of inactivity (no usage of mouse or
keyboard) before the computer enters Hibernation mode -- in which the state
of open programs and documents is saved to the computer's hard disk drive.
The computer is shut OFF in Hibernation mode, so that very little power is
consumed.
Be sure to save your documents and other files frequently as you work on
them, to create permanent copies of them on the computer's hard disk drive.
Saving the state of documents with Hibernation mode does not create
permanent copies of them; it is just a way to save power as you pause in
your work, and then quickly pick up where you left off.
USB settings �> USB selective suspend setting
Prevents or allows idle USB devices and ports to be shut off to conserve
power. Some computers include built-in devices that are connected internally
via USB.
Power buttons and lid �> Lid close action
Specifies the computer's response to closing the display lid: enter Sleep
mode, enter Hibernation mode, shut down (turn off), or do nothing. This
option provides a very convenient way to put the computer to sleep before
boarding a plane or leaving the office for a meeting.
Power buttons and lid �> Power button action
Specifies the computer's response to pressing the power button: enter Sleep
mode, enter Hibernation mode, shut down (turn off), or do nothing.
Power buttons and lid �> Sleep button action
Specifies the computer's response to pressing the Sleep button: enter Sleep
mode, or enter Hibernation mode. Most Toshiba computers do not have a Sleep
button, but there are many other ways to place the computer in Sleep or
Hibernation mode, including closing the display lid (see setting above), or
selecting Sleep or Hibernation from the Windows Start Menu.
Power buttons and lid �> Start menu power button
Specifies the computer's response to clicking the on/off icon on the Start
Menu : enter Sleep mode, enter Hibernation mode, or shut down (turn off).
PCI Express --> Link State Power Management
Specifies no (off), moderate, or maximum power savings for PCI Express
devices, at the expense of perfomance.
Processor power management--> Minimum processor state
Specifies the lower limit of CPU performance, as a percentage of the full
potential performance of the CPU. Higher values promote higher performance
(depending on CPU utilization), at the expense of greater power consumption.
Processor power management �> Maximum processor state
Specifies the upper limit of CPU performance, as a percentage of the full
potential performance of the CPU. Higher values promote higher performance
(depending on CPU utilization), at the expense of greater power consumption.
The minimum and maximum processor state values are essentially percentage of
the maximum clock rate for the CPU, though other factors may be involved.
For further details, see Microsoft's document Processor Power Management in
Windows Vista and Windows Server 2008.
Search and Indexing �> Power Savings Mode
Specifies the prioritization of search-indexing that runs 'in the
background' (when the computer is not busy with standard applications such
as e-mail and web browsing). Options are: performance, power saver, and
balanced. Selecting "performance" allocates the highest priority to these
background tasks, speeding up their execution -- at the expense of power
consumption.
Display �> Turn off display after
Specifies the number of minutes of inactivity (no usage of mouse or
keyboard) before the display is turned off. Since the display and its
backlight represent a large percentage of the computer's total power
consumption, selecting a relative low timeout value can allow the computer
to run from its battery much longer than it would otherwise (if the computer
is not being used continuously).
Display �> Adaptive display
Turns the Adaptive Display feature on or off. When on, the Turn Off Display
After timeout (above) is lengthened if the computer is frequently 'active'
shortly after the display is turned off (if you move the mouse or tap a key
to turn the display on again immediately after it goes off).
Display �> Display brightness
Specifies the default brightness of the display when running from battery
power and from AC power -- as a percentage of the maximum brightness of the
display panel. On many Toshiba portable computers, Fn+F6 and Fn+F7 key
combinations may be used to decrease or increase the display brightness.
Multimedia settings �> When sharing media
Specifies whether the computer will enter either Sleep mode or Away mode
when it receives a request to enter Sleep mode. There is one exception to
this rule: when the request to enter Sleep mode comes from the Sleep �->
Sleep After timeout (see the description above), the computer will enter
Sleep mode, even if Away mode is selected in this setting. Requests for the
computer to enter Hibernation mode are not affected by this setting. Away
mode causes the computer to appear to be Off (or in Sleep mode) while it is
still capable of processing background media tasks such as recording
television content or streaming media to other devices. For more information
about Away mode, see the Microsoft white paper Away Mode in Windows Vista.
Battery �> Critical battery action
Specifies what should happen when the battery's charge reaches a critical
low level. Options include Sleep mode, Hibernate mode, and Shut down, and
also Do Nothing (the default, if the computer is plugged in to AC power).
Battery �> Low battery level
Specifies the percentage of battery power considered to be 'low'.
Battery �> Critical battery level
Specifies the percentage of battery power considered to be 'critical'.
Battery �> Low battery notification
Specifies whether or not a pop-up message is displayed when the battery
reaches the low battery level setting.
Battery �> Low battery action
Specifies what should happen when the battery's charge reaches a low level.
Options include Sleep mode, Hibernate mode, and Shut down, and Do Nothing
(the default).

Subject: [BlindHandyMan] Laptop Fan Constantly Runnin!
Hi,
Can anyone give me any ideas as to why my laptop fan seems to constantly
run, as of late?
The bottom of the unit doesn't feel hot; it does a good job of keeping it
pretty cool, but should it constantly be running?
This is a Toshiba laptop; it's 3 years old!
