Power 
ManagementThe following power management features are available for 
conserving AC power and extending battery operating time: 
n     Advanced Power Management (APM)
n     Power Management Settings
n     Sleep
n     Hibernation
n     Battery Operating Time
Advanced Power Management (APM)
APM is installed on the computer and requires no action from 
the user to reduce power consumption. APM turns off the 
processor between keystrokes and when the system is idle. 
The idle function can be disabled by the user.
Power Management Settings
You can select power conservation settings through Power 
Management located on the System Features menu in 
Computer Setup. Computer Setup can be accessed by 
pressing F10 when the cursor blinks on the upper-right 
corner of the display screen during system reboot. These 
settings control the power conservation rate and the timeout 
values for various system components. A timeout is a 
specified period of system or component inactivity. After this 
period, the system or component (for example, the hard 
drive) is shut down to conserve power until it is accessed 
again.
There are four categories of power management settings: 
Maximum Power Saving, Maximum Performance, Customized, 
and Disabled. The default setting for each feature is listed in 
Table 1-9.

* Idle Mode: Determines processor speed.  For Auto, 
processor is throttled to 50% of maximum clock sped only 
during inactivity.   When On, processor is always at 50% of 
maximum clock speed.  When Off, processor is always at 
maximum clock speed.
Sleep
Sleep is a power conservation mode that performs the 
following functions: 
n     Places the computer in a lower power state after a selectable period of \
inactivity. Noticeable to the end-user, the panel is powered off and the\
 
hard drive is spun down. 
n     Automatically reduces the amount of power the computer uses. 
n     The computer is immediately ready for use when any key is pressed.
n     Sleep mode is indicated by the Sleep (moon shaped) icon on the 
Status Panel.
The computer may be manually put in Sleep mode by 
pressing the Fn + F4 keys.
Hibernation
Hibernation is a power conservation mode that performs the 
following functions: 
n     Saves all current information from memory and saves it to a file on 
the hard drive.
n     Turns off the computer.
n     Can be restored after any amount of time.
The Hibernation file is preinstalled on the hard disk. The 
Hibernation file is slightly larger than the total RAM memory 
of the computer (system memory, memory expansion board, 
and video memory). The Hibernation 100-MB file can be 
reinstalled with the QuickRestore CD.  The system comes 
configured with a hibernation file large enough to support 96 
MB of DRAM.  Please refer to C:\HIBERNATE\HELP.TXT to 
customize the hibernation file size.
Hibernation is initiated by one of the following means: 
n     Automatically when the battery reaches a low battery level, if 
preselected.
n     Manually by simultaneously pressing the power button.  By holding 
the power button for more than four seconds, the system will power 
off instead of hibernating.
When the Power button is pushed, the computer exits 
Hibernation.
Battery Operating Time
Battery operating time is affected by variables, such as the 
following: 
n     Power conservation settings
n     Hardware configuration
n     Software applications
n     Installed options
n     Display brightness
n     Hard drive usage
n     Power button
n     Changes in operating temperature
n     Type and number of installed PC Cards
Refer to Appendix B for information on increasing battery 
pack operating time, conditioning the battery pack, and 
disposing of a used battery pack.
