POWER MANAGEMENT

Your UH-X has many options and features for

conserving battery power. Some of these

features are automatic and need no user

intervention. However, others depend on the

parameters you set to best suit your operating

conditions, such as those for the display

brightness. Internal power managements for

your notebook may be controlled from settings

made in your operating system, pre-bundled

power management application, or from

settings made in BIOS setup utility.

Besides the options available for conserving

battery power, there are also some things that

you can do to prevent your battery from

running down as quickly. For example you can

create as appropriate power saving profile, put

your notebook into Suspend mode when it is

not performing as operation, and you can limit

the use of high power devices. As with all

mobile, battery power computers, there is a

trade-off between performance and power

savings.

Power Button

When you UH-X is active, the Power button

can be used to manually place your notebook

into Sleep mode. Push the Power button when

your notebook is active, but not actively

accessing anything, and immediately release

the button. You will hear two short beeps* and

your system will enter Sleep mode.

If your UH-X is Sleep mode, pushing the Power

button returns your notebook to active

operation.

You can tell whether the system is Suspended

by looking at the Power indicator. If the

indicator is visible and not ﬂashing, your

notebook is fully operational. If the indicator is

visible and ﬂashing, your notebook is in Sleep

mode. If the indicator is not visible, the power

is off or your notebook is in Hibernation mode.

(See Hibernation Feature)

* Only applicable for some models

Sleep Mode

Sleep mode in Windows saves the contents of

your notebook's system memory during

periods of inactivity by maintaining power to

critical parts. This mode will turn off the CPU,

the display, the storage drive, and all of the

other internal components except those

necessary to maintain system memory and

allow for restarting. Your notebook can be put

in Suspend mode by:

• Pressing the Power button when your

system is turned on.

• Selecting sleep from the Windows Power

menu.

• Timing out from lack of activity.

• Allowing the battery to reach the Dead

Battery warning condition.

Press the power button to resume.

Your notebook's system memory typically

stores the file on which you are working you

are working, open application information, and

any other data required to support operation

from Sleep mode, your notebook will return to

the point where it left off.

There must be as adequate power source

available, or your notebook will not resume.

 If you are running your UH-X on

battery power, be aware that the

battery continues to discharge while

your notebook is in Suspend mode,

though not as fast as when fully

operational.

 The main advantage of using the

Hibernation (Save-to-Disk) function is

that power is not required to maintain

your data. This is particularly

important if you will be leaving your

UH-X notebook in a suspended state

for a prolonged period of time. The

drawback of using Hibernation mode is

that it lengthens the power down and

power up sequences and resets

peripheral devices.
