Managing Your Notebook's Power
See Battery for more information on getting the best performance from
battery packs.
Use your notebook connected to an electrical outlet as often as
possible, as battery life expectancy is affected by the number of times it
it is charged.
When leaving your notebook unattended for long periods, place it in
standby or hibernate mode. You can exit either power management
mode by pressing the power button.

after a preset period of inactivity (a time-out). When standby mode is
exited, your notebook will return to the same operating state it was in
before entering standby.
If your notebook loses power from both the electrical outlet and the
battery while in standby mode, data may be lost.
To enter standby mode in Windows XP:
Start -> Turn off computer -> Stand By.
or
You can set your notebook to go to Standby Mode:
When you close the lid of your notebook
When you press the power button
via the Advanced tab settings in Power Options Properties
(accessed via Start -> Control Panel -> Pick a category ->
Performance and Maintenance -> Power Options).
To exit standby mode, press the power button. You can exit standby
mode by pressing a key or touching the touch pad. For more
information on standby mode, see Turning Your Notebook On and Off,
Chapter 2.
Top
Hibernate Mode
In Hibernate mode, power is conserved by system data being copied to
the hard drive, and your notebook completely turning off. When
hibernate mode is exited, your notebook will return to the same
operating state it was in before entering hibernate mode.
Hibernate Mode can be enabled/disabled in the Power Options
Properties window.
If enabled, your notebook will go into hibernate mode if the battery
charge level becomes critically low.
Depending on how you set the Power Management Options on the
Advanced tab in the Power Options Properties window, use one of the
following methods to enter hibernate mode:
When you close the lid of your notebook
When you press the power button
Start -> Turn Off Computer -> Hibernate (if the Hibernate option
does not show, press Shift, and the Standby option will switch to
Hibernate).
If the Hibernate option is not available for these methods, Hibernate
mode has not been enabled. Check the Enable Hibernation box on the
the Hibernate tab of the Power Options Properties window and click
Apply to enable Hibernation.
If your PC Cards do not operate correctly after exiting hibernate mode,

remove and reinsert the card or restart your notebook.
To exit hibernate mode, press the power button. You cannot exit
hibernate mode by pressing a key or touching the touch pad. For more
information on hibernate mode, see Turning Your Notebook On and Off,

SpeedStep
Your notebook is equipped SpeedStep technology to better manage
power consumption. It changes the processor speed to find the best
balance between your computing performance and power consumption
needs. Higher speeds enjoy better performance, while slower speeds
conserve more power.
In Windows XP, the processor's performance level depends on the
Power Scheme you select (see Power Options Properties, section
6.1.3). You do not need to make any further adjustments to set the
performance level. Each preset power scheme has different time-out
settings for entering standby mode, hibernate mode, turning off the
display, and turning off the hard drive. For example, the
Portable/Laptop mode automatically changes SpeedStep modes
depending on if you are running the computer on AC power or batteries
in order to prolong battery usage while still providing optimal
performance. You can also individually alter and save each of these
settings and schemes if desired.

Windows XP automatically chooses the SpeedStep mode to find the
most appropriate speed for your processor according to the Power
Scheme you choose and your current system demands.

Battery Performance
Using a battery lets you work with your notebook without connecting it
to an electrical outlet. Your notebook comes with one 8-cell Li-Ion
battery pack installed, which will give you more than 300
charging/discharging cycles.
The performance of the battery can vary, depending on operating
conditions. Your battery may last less time if you are running powerintensive programs, playing CDs or DVDs, using PC cards or have high
high display-brightness settings.
The Power Management Options can be set to alert you when the
battery charge is low.
Ensure any battery you use is compatible. Failure to do so may risk fire
or explosion. For more details on purchasing compatible batteries, talk
to your notebook retailer.
Batteries should never be disposed of with household waste. Contact
your local waste disposal or environmental agency for advice on
disposing of used lithium-ion batteries.

Low-Battery Warning
The Power System
第 7 頁，共 8 頁
After a low-battery warning, save your work immediately, then connect
your notebook to an electrical outlet. Hibernate mode will begin
automatically if the battery runs completely out of power.
You will hear the low-battery warning when the battery charge is
approximately 90 percent depleted. Your notebook will beep once,
indicating approximately 10 to 15 minutes of battery operating time
remain. If you do not connect your notebook to alternative power source
source during that time, there will be a periodic beep. Your notebook
will automatically enter hibernate mode if the battery charge reaches a
critically low level. For more information, see Power Management,
section 6.1.
Top
Charging the Battery
When connected to an electrical outlet, a completely discharged battery
battery will charge in 3 to 5 hours (depending on whether your notebook
notebook is on or off and what programs, if any, are running). You can
leave the battery in your notebook as long as you like. The battery's
internal circuitry prevents the battery from overcharging.
Before using the battery for the first time it must be charged. Connect
the computer to an electrical outlet and allow the battery to fully charge,
charge, indicated by the battery indicator light on the front panel of the
notebook.
Once a battery pack is fully charged for the first time, use your notebook
notebook on battery power until the battery discharges completely. This
This will extend battery life, and helps ensure accurate monitoring of
battery capacity.
If necessary, the battery will be charged whenever your notebook is
connected to an electrical outlet.
The battery will not be charged if it or your notebook is too hot, either
from use or being in a hot environment. If this occurs the battery
indicator will light red. Disconnect your notebook from any electrical
outlet, and allow it and the battery to cool to room temperature. You can
can then reconnect your notebook to the electrical outlet and charge the
the battery. The battery indicator will also light red if the battery is bad
bad and needs replacing.

2.
Press it into place gently but firmly until the latch locks it into place
Top
Storing a Battery
If storing your notebook for an extended period of time, remove the
battery. Fully charge the battery before using your notebook again.
Top
Working With Extra Battery Packs
If you spend a lot of time traveling, working without connecting your
notebook to an electrical outlet, it may be a good idea to carry additional
additional battery packs so you can quickly replace a discharged battery
battery and continue working.
Top
Maximizing Battery Life
A battery can be recharged many times, but over time it will lose its ability
to hold a charge. To maximize battery life:
Don't leave your notebook plugged in and unused for more than a few
few hours. Overcharging may shorten battery life.
If you will not be using your notebook for a long period, remove the
battery.
If you have a spare battery pack, alternate the batteries.
Ensure your notebook is off when replacing the battery.
Store spare battery packs in a cool, dry place, out of direct sunlight.
