Turning off power-consuming peripherals
Peripheral devices on your computer use power. For instance, your
Tablet PC may have a wireless network connection, a modem card or
USB devices. Because some of these peripherals can draw a
significant amount of power, you should consider unplugging them or
turning them off in situations where you want to conserve battery
power. For information on turning off your wireless network connection,
please refer to the manufacturer's documentation.
Using power schemes
Power schemes are a collection of settings that manages the power
usage of your computer. You can select from a number of power
schemes that are available in Power Options in the Control Panel, you
can adjust individual settings of any available power scheme, or you
can create your own power schemes to suit your particular system and
preferences.
Standby
Standby is a low-power state in which your monitor and CPU turn off.
When you want to use the computer again, it comes out of standby
quickly and your desktop is restored exactly as you left it. Use standby
to save power when you will be away from the computer for a short
time while working.
Hibernation
Hibernation is a state in which your computer shuts down to save
power but first saves everything in memory on your hard disk. When
you restart the computer, your desktop is restored exactly as you left it.
Use hibernation to save power when you will be away from the
computer for an extended time.

Adjusting Screen Brightness and Backlight Settings
The Hammerhead XRT comes with a Utility program that provides
additional functionality to your computer. To launch the HH Control
Panel program, click on the icon found in the quick launch bar.
If the icon is not found, you can launch the program by clicking on
START, ALL PROGRAMS, HH Utilities, HH Control Panel.
Adjusting screen brightness
The brightness of your Tablet PC screen is often the number one
consumer of power, so you can conserve battery power by turning
down the screen brightness on your Hammerhead XRT. For optimal
battery function we recommend that your computer is set for “Auto Off”
in bright light, “Auto Dim” in low light and the advanced backlight
settings are loaded with default settings. This configuration is designed
to give you an optimal balance between performance and battery life.
For computers with transmissive (indoor viewable) displays, it is highly
recommended that you do not use the “Auto Off” backlight settings.
Manual brightness adjustment
The brightness slider control allows you to manually adjust the
backlight brightness. Click on the bar and slide it to the left or right to
achieve the desired brightness.

Auto backlight settings
To have the backlight automatically turn off in direct sunlight, check the
“Auto Off in Bright Light” option.
To have the backlight automatically dim in low light conditions, check
the “Auto Dim in Low Light” option.
Side button function
The Side Button Option allows you to have the system respond to the
Windows side button options, or toggle the backlight on & off.
To have the side button function set to Windows defined options, click
on the “Windows Defined” button. Note: Windows side button options
can be found under Control Panel / Power Options / Advanced / Power
Button.
To have the side button set to toggle the backlight on and off, click on
the “Back Light” option.
Advanced backlight
Your computer is delivered preset with the optimal settings for most
users. For those users with special needs, such as optimizing
operation in dark environments, the Advanced Backlight settings allow
for optimal backlight performance. To make modifications to the
backlight settings, click on the Advanced Backlight button.
To help you optimize the settings
for your special needs, the red tick
mark on the red line indicates the
current ambient light level. If the tick
mark is located to the left, there is
little ambient light. As the ambient
light becomes brighter, it will move
further to the right.

Backlight adjustment
Sliding the pink line left or right will
set the light level at which you want
the backlight to go off. If the
ambient light is greater than this
setting (i.e. ambient light is to the
right of this line) the backlight is
turned off. If the ambient light is
less than this setting (i.e. to the left
of this line) the backlight will be on.
Note: You will only be able to move the pink line within the “Sunlight”
range of the light meter indicated at the bottom.
Auto dim
The blue line represents the
minimum backlight setting at low
light levels. Sliding the blue line
up or down sets the auto dim
brightness level. Up is brighter;
down is darker. The red line
represents the minimum
backlight level and the top of the
window represents maximum
backlight level.
Note: The auto dim adjustment tab’s size can be adjusted. Hitting Alt-S
using a keyboard will enable you to grab the red line and slide it until
the desired size of the tab is reached.
The orange segment represents the
light level at which the backlight is
at full brightness. At light levels
lower than this, Auto dimming takes
place, as represented by the
sloping yellow line. This full
brightness setting can be adjusted
by dragging the orange line to the
right or to the left.
