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
Different patterns of Notebook use determine the level of power management needed.
These power management levels can be initiated based on the amount of time passed
since the last system activity. System activity examples include keyboard strokes or 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 the system. If the Notebook is on a network, Compaq recommends that System
Standby be set to Never.

Low-Power Modes
Compaq Presario 1600XL Series Notebook Computers have two levels of low-power
management: Hibernation and Standby.
Hibernation
Hibernation helps conserve battery life and protect data. The 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 its 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 when finished has two advantages: 1. It enables the
Notebook to wake up faster than if it had been turned off completely; 2. It saves more
power than the active (On) mode.
Activate Sleep mode by pressing Fn+F4. Or click Start, select the Shut Down option, and
click Standby.
CAUTION:

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.

Servicing the Notebook - Full Off Mode
The Notebook must be turned off completely when installing or replacing components in
the system. Follow the instructions for putting the Notebook into Off mode properly,
unplugging it from the outlet, and removing the battery (see Battery Pack Removal
Sequence).
Rebooting After a Lockup
To reboot the Notebook (from a cold start) when the keyboard is frozen or the screen is
locked, press and hold down the Power button for at least four seconds; this causes a
manual shutdown. Then, restart the Notebook with a single press of the Power button.
If the Notebook still does not recover, press the Power button and hold for four seconds to
shut it down, then remove the battery or unplug the AC power for at least 30 seconds.
Reinsert the battery or reconnect AC power and press the Power button once to reboot.
Recovering From a Loss of Electrical Power
Loss of electrical power causes the Notebook to turn off automatically. This may cause loss
of data because the Microsoft Windows operating system is not able to close all files and
programs properly.
Loss of power may be caused by one of the following:
• Electrical power service is interrupted.
• The power cord is accidentally disconnected.
If power surges or sags, the display and status lights may flicker, and the Notebook may
automatically restart. If an improper shutdown occurs, the Microsoft Windows utility
program, ScanDisk, runs automatically once power is restored. ScanDisk determines
whether the improper shutdown caused any errors on the hard disk. These errors may
occur if the Microsoft Windows operating system is not able to close all files properly before
the shutdown. If no errors are found, the restart process continues. If ScanDisk does detect
errors, follow the instructions on the screen to continue the restart process. Work that was
not saved before the loss of power or shutdown may be lost.
If a power failure occurs, or the power cord disconnects while the Notebook is turned on,
turn it off until normal service is restored. The next time the Notebook is turned on,
ScanDisk may run to check the hard disk for errors caused by improper shutdown.
