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 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 button once.
To resume from Hibernation mode, press the Power 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 mode instead
of turning off the Notebook when finished has two advantages: 1. It allows the Notebook to
wake up faster than turning it off; 2. It saves more power than the Active-On mode.
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.
Ä
To activate Standby/Sleep mode, press Fn+F4 or click Start, select the Shut Down
option, and then Standby.
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 shutdown without saving the data.
To activate Off mode, click the Start button on the Windows taskbar, click Shut Down,
and then select shutdown from the options.
To resume from Off mode, press the Power button once.
WARNING: The Notebook must be shutdown (Off mode) when installing or
replacing components. Follow the instructions for putting the Notebook into Off
Å
mode, unplug it from the outlet, and remove the battery pack (see Removing the
Battery later in this guide) before servicing any parts.

Power Settings
Power management levels 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
Differing 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 from the Control Panel, and 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.
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.
The following table shows the default settings for each Power Scheme.

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, ScanDisk, a Microsoft Windows
utility program, runs automatically once power is restored. ScanDisk determines if 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-Operating Life
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 temperature
•Type and number of installed PC Cards
Note: The power consumption requirements for PC Cards vary widely. Some cards drain
the battery pack very rapidly.
Battery pack operating time 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 steps:
•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
amount 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
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
CAUTION: To avoid a loss of data, ensure that all information is saved before
completely discharging the battery pack.
Ä
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 re-conditioned. Plug in the AC adapter and begin using the Notebook.
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.
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
Ä
harmful battery components.

Removal and Replacement
This chapter details removing and replacing each component of the Presario 1800XL
Notebook Computers.
Electrostatic Discharge
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 not seem affected and 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 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.

Cables
Most cables used throughout the unit are ribbon cables.
Cables must be handled with extreme care to avoid damage. Use the following precautions
when handling cables to avoid damage to the cable and Notebook:
•Always handle cables by their connectors.
•In all cases, avoid bending, twisting, pulling, or tearing cables.
•Apply only the minimum force required to seat or unseat cables from their
connectors.
•Ensure that cables are routed in such a manner that they cannot be caught or
snagged by parts being removed or replaced.
•Handle flex cables with extreme care; they can tear easily.
