Battery and Power Management
This chapter describes power management and proper battery operating practices for
Presario 1800XL Series Notebooks. These practices include conservation of AC power and
extending the operating life of the battery. The following sections also outline proper
methods to start and shut down the Notebook in various situations.
Power Modes
Presario 1800XL Series Notebooks have three levels of low power: Hibernation, Standby,
and Off.
Hibernation
Hibernation mode 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 shutdown. When the Notebook wakes from Hibernation, it returns to its former
state.
Note: When the Notebook enters or wakes from Hibernation mode, a Progress window is
displayed.
To activate Hibernation mode, press the Power ª button once.
To resume from Hibernation mode, press the Power ª button once.
Standby
Standby is a low-power mode, also referred to as Sleep mode. The Notebook maintains
system information and open files while in Standby mode. Selecting Standby instead of
turning off the Notebook when you have finished working has two advantages: 1. It allows
the Notebook to wake up faster; 2. It saves more power than the Active-On mode.
Ä
CAUTION: 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.
To activate Standby/Sleep mode, press Fn+F4 or click Start, click Shut Down, and then
select Standby from the options.
To resume from Standby/Sleep mode, press any key.

Full Off
Off mode consumes no power. However, the battery charges while the Notebook is in Off
mode if the battery is installed and the Notebook remains plugged into external AC power.
Note: Unsaved information is lost if the Notebook is shut down without saving the data.
To activate Off mode, click the Start button on the Windows taskbar, click Shut Down,
and then select Shut down from the options.
To restart the Notebook from Off mode, press the Power ª button once.
Å
CAUTION: The Notebook must be in Off mode (completely shut down) when
installing or replacing components. Follow the instructions for putting the
Notebook into Off mode, unplug it from the outlet, and remove the battery pack
before servicing any parts.

Power Settings
Power management modes can be initiated based on the amount of time passed since the
last system activity. System activity includes keyboard strokes, mouse movement, CD/DVD
playback, or modem use.
Power Schemes
Different patterns of Notebook use determine the level of power management needed.
Power management settings can be selected using several predefined Power Schemes.
To access these options, select Power Management on the Control Panel, then click the
Power Schemes tab. The default Power Schemes are Home/Office Desk, Portable/Laptop,
and Always On. Power Schemes can also 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.
•
Hibernate: length of inactivity before the Notebook goes into Hibernation 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.

Rebooting After a Lockup
To reboot the Notebook when the keyboard is frozen or the screen is locked, press and hold
down the Power ª button for at least four seconds; this causes the Notebook to shutdown.
Then, restart the Notebook with a single press of the Power ª button.
If the Notebook still does not recover, press the Power ª button and hold for four seconds
to shut it down, then remove the battery and unplug the AC power for at least 30 seconds.
Reinsert the battery or reconnect AC power and press the Power ª 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.

Increasing Battery Pack Operating Time
Battery pack operating life is affected by several variables. To avoid unnecessary
replacement, consider the following when determining how long a charged battery pack
should last:
•
Power conservation settings
•
Hardware configuration
•
Software applications
•
Installed options
•
Display brightness
•
Hard drive usage
•
Changes in operating temperatures
•
Type and number of installed PC Cards
Note: Power consumption requirements for PC cards vary widely. Some cards drain the
battery pack very rapidly.
Battery pack operating life can be increased by as much as 50 percent by controlling the
energy required by the Notebook and the energy stored in the battery pack.
Minimizing the Energy Required
To minimize the energy required by the Notebook, follow these guidelines:
•
Set the power conservation levels in the Power Management utility to Maximum.
•
Customize the time-out value to work more efficiently with the applications. The
length of battery life depends on the values selected.
Maximizing the Energy Stored
To maximize the energy stored in the battery pack, follow these guidelines:
•
Condition the battery pack at least every 30 days to improve overall battery
performance.
•
Keep a battery pack in the Notebook when using it with AC power to supply the
battery pack with a constant trickle charge.
•
Store the battery pack in a cool, dry place when not in use.

Conditioning a Battery Pack
Ä
CAUTION: To avoid losing data, Make sure that all information is saved before
completely discharging a battery pack.
To condition a battery pack, complete the following steps:
1. Plug in the AC adapter and allow the battery to charge until the fast charge arrow on
the status display disappears. The battery gauge may read 100% for a period of time
before the arrow disappears.
Note: Do not unplug the AC adapter until the arrow disappears.
2. Unplug the AC adapter and allow the battery to drain until the Notebook enters
Hibernation mode. The Notebook can be used normally during this process.
Note: If the AC adapter is connected while the battery is draining, the process must be
repeated beginning with step 1.
The battery is now reconditioned. Plug in the AC adapter and begin using the Notebook.
The table below shows typical battery charging times.

Disposing of a Used Battery Pack
In the interests of safeguarding our environment, Compaq Computer Corporation
recommends that nickel metal hydride (NiMH) and lithium-ion (Li-ion) battery packs be
recycled. Battery packs should be handled in accordance with country, state, province, or
local regulations.
Ä
CAUTION: Never attempt to open or service a battery pack. Opening a battery
pack not only damages the pack and makes it unusable, it also exposes potentially
harmful battery components.

Removal & Replacement
This chapter details the necessary preparations for disassembling the Notebook and
explains removing and replacing each component of the Presario 1800XL Series Notebooks.
Electrostatic Discharge
Ä
CAUTION: When removing or replacing parts, be careful to discharge static
electricity before touching the Notebook’s internal components.
A sudden discharge of static electricity from a finger or other conductor can destroy
static-sensitive devices and microcircuitry. Often the spark is neither felt nor heard, but
damage occurs. An electronic device exposed to an electrostatic discharge may work
perfectly throughout a normal cycle. However, the discharge degrades internal layers,
which reduces the operating life of the device. Networks built into many integrated circuits
provide some protection, but in many cases the discharge still contains enough power to
alter device parameters or melt silicon junctions.
The table below shows the amount of static electricity generated by common activities
associated with servicing computers.

Screws
The screws used in the Notebook are not interchangeable. If an incorrect screw is used
during the reassembly process, it can damage the unit. Compaq strongly recommends that
all screws removed during disassembly be kept with the part that was removed, then
returned to their proper locations.
Important: As each subassembly is removed from the Notebook, place it together with
its screws away from the work area to prevent damage.
Connectors & Plastic Parts
Plastic parts can be damaged by the use of excessive force during dissassembly and
reassembly. When handling plastic parts, use care. Apply pressure only at the points
designated in the instructions.
