Power Management
The following power management features are available for conserving AC power and
extending battery operating time:
•Power Management Settings
•Low-Power Modes
•Battery Operating Life
•Servicing the Notebook - Full Off Mode
•Rebooting after a Lockup
•Recovering from a Loss of Electrical Power
Power Management Settings
Differing patterns of Notebook use determine the level of power management needed.
These power management levels can be initiated based on the amount of time since the
last system activity. System activity includes keyboard strokes, mouse movement, DVD/CD
playback (while under program control that monitors Standby), and modem use.
Power Schemes
You may select different settings or Power Schemes through Power Management from
the Control Panel. The default Power Schemes are Home/Office Desk, Portable/
Laptop, and Always On. The settings can be customized by changing the following
options:
•System Standby: length of inactivity before the Notebook goes into Standby
mode
•Turn Off Monitor: length of inactivity before the screen times out and goes blank
•Turn Off Hard Disks: length of inactivity before the hard drive goes into low
power mode
Important: The setting for the Hard Disk must be less than or equal to the setting
for System Standby. If the Notebook is on a network, Compaq recommends that
System Standby be set to Never.

Presario 1200 Series

Low-Power Modes
Compaq Presario 1200 Series Notebook Computers have two levels of low-power
management: Hibernation and Standby (also known as Sleep mode).
Hibernation
Hibernation helps conserve battery life and protect data. Your Notebook automatically
enters Hibernation mode when the battery has little power left or when the Notebook
(operating on battery power) is in Standby mode for more than one hour. As the Notebook
enters Hibernation, it automatically stores the contents of the Notebook memory to the
hard drive before it shuts down. When the Notebook comes out of Hibernation, it returns to
its former state.
Activate Hibernation mode by pressing the Power button once.
To restart the Notebook, press the Power button once. When the Notebook enters or
wakes from Hibernation mode, a Progress window is displayed on the screen.
Standby
Standby is a low-power mode, also referred to as Sleep mode. Selecting Standby mode
instead of turning off the Notebook has two advantages: It allows the Notebook to wake up
faster than turning it completely off; and it saves more power than the active (On) mode.
To activate Standby/Sleep mode, complete one of the following:
•Press Fn+F4.
•Click Start, select the Shut Down option, and click Standby.
Ä
ÄÄ
Ä
CAUTION: The Notebook maintains system information and open files while in
Standby mode. However, unsaved information is lost if the Notebook is turned off
prior to system wake-up, or if a power loss occurs while using the AC adapter.
