Battery Pack Operating Time
This appendix covers the following information concerning battery pack operating time:
●
●
●
Increase battery pack operating time
Conditioning a battery pack
Disposal of a used battery pack
Increasing Battery Pack Operating Time
Battery pack operating time differs depending on several variables. To avoid unnecessary replacement, consider
the following variables when determining how long a charged battery pack should last:
●
Power management 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
computer and the energy stored in the battery pack.
Minimizing the Energy Required
To minimize the energy required by the computer, follow these steps:
file:///C|/SERVICE%20MANUALS/COMPAQ%20_%20check...SARIO%201270,%201670,%20and%201675/battery.html (1 of 3)6/27/2004 2:46:05 AM
file:///C|/SERVICE%20MANUALS/COMPAQ%20_%20checked%20ok/NOTEBOOKS/PRESARIO%201270,%201670,%20and%201675/battery.html
●
●
Set the power conservation levels in the Power Management utility to Maximum.
Customize the timeout 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 at least every 30 days to improve overall battery performance.
Keep a battery pack in the computer 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 data is saved before 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 LED light on the display stops
blinking. Your battery gauge may read 100 percent for a period of time before LED light on the display
stops blinking. Do not unplug the AC adapter until the arrow disappears.
2. Unplug the AC adapter and allow the battery to drain until the computer reaches hibernation and
turns itself off. Do not plug in the AC adapter during this process or you will need to restart
with Step No. 1. You may use the computer while the battery is draining.
3. Your battery is re- conditioned.
4. Plug in the AC adapter and begin using the computer.
The table below shows the approximate battery pack charge times.

Disposal of a Used Battery Pack
In the interest 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, but also expose potentially harmful battery components.

Power Management Settings
Depending on your patterns of computer use, you can set different levels of power management. These different
power management levels can be activated based on the amount of time passed since the last system activity.
System activity examples include keyboard or mouse movement, CD or DVD playback (while under program
control that monitors Sleep), and modem use.
You can select different conditions or power schemes through Power Management.The optional settings are
Home/Office Desk, Portable/ Laptop, and Always On. From the default settings, you can change the
following settings:
●
●
●
the System goes to Sleep (Standby) mode
the screen times out and goes blank
the hard drive spins down
Each of these system components will go to sleep after the selected or default periods of inactivity. (The setting
for hard drive must be less than or equal to the setting for System.)
IMPORTANT: If you’re on a network, it’s recommended that you set System Standby to Never.
There are five categories of power management settings under the Control Panel. The default setting for each
feature is listed below in the tables.

Sleep
You can select Sleep mode instead of turning off the computer when you have finished using it. This allows the
computer to wake up faster than turning it completely off and saves power over the active (On) mode. Compaq
Presario Series Notebook computers have two levels of sleep, Hibernation and Sleep.
Hibernation – by pushing the power button once your computer will perform a save to disk followed by a shut
down of the computer into Off mode.
Sleep – is a low power mode, also referred to as Standby mode. While in Sleep mode, your computer will
maintain system information and open files. Unsaved information will be lost if you turn off your system prior to
system wake-up, or if you lose power while using the AC adapter.
While in Sleep mode, your computer will maintain system information and open files.
Unsaved information will be lost if you turn off your system prior to system wake-up, or if you lose
power while using the AC adapter.

"Compaq.com - Compaq Presario Series Maintenance and Service Guide - Models : 1270, 1670, and 1675
Hibernation Mode
Hibernation helps conserve battery life and protects your data. Hibernation can be a routine power saving event,
or can be the result of a low battery condition. As it enters Hibernation your computer will display a progress
screen, as it automatically saves the machine state before it shuts down and turns itself off. Your computer will
automatically go into Hibernation, when the battery has little power left, or when the system (operating on battery
power) has been in Sleep mode for more than an hour. You can also manually initiate Hibernation by pressing the
power button once while the system is active. To restore the computer’s previous state, simply press the power
button once again. While waking up, the computer will display a progress screen.
The following table shows the conditions and indicators for getting in and out of the various power management
modes, Sleep, Hibernation, and Off.

"Compaq.com - Compaq Presario Series Maintenance and Service Guide - Models : 1270, 1670, and 1675
Rebooting After a Lockup
Occasionally you may encounter a frozen keyboard or a locked screen. To reboot your computer (as if from a cold
start) press and hold down the Power Button for at least four seconds, which will cause a manual shutdown. Then,
restart it with a single press of the Power Button. If it still doesn’t recover, press the Power Button and hold it 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.
Battery Operating Time
Battery operating time is affected by variables, such as the following:
●
Power conservation settings
●
Hardware configuration
●
Software applications
●
Installed options
●
Display brightness
●
Hard drive usage
●
Power button
●
Changes in operating temperature
●
Type and number of installed PC Cards

Electrostatic Discharge
A sudden discharge of static electricity from a finger or other conductor can destroy staticsensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage
occurs. An electronic device exposed to electrostatic discharge (ESD) may not be affected
at all and will work perfectly throughout a normal cycle. Although, it may function normally
for a while, then degrade in the internal layers, reducing its life expectancy.
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 shows how different activities generate static electricity and at different
electrostatic voltage levels.

Service Considerations
Listed below are some of the considerations that you should keep in mind during the
disassembly and assembly of the computer.
Tool and Software Requirements
To service the computer, you need the following:
●
●
●
●
●
●
Compaq screwdriver kit (Spare Part No. 161946-001)
Torx T-9 screwdriver
3/16-inch and 5mm nut drivers (for screwlocks and standoffs)
Small, standard screwdriver
Small, Phillips screwdriver
Diagnostics software
Screws
The screws used in the computer 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 computer, it should be placed
away from the work area to prevent damage.

Cables and Connectors
Most cables used throughout the unit are ribbon cables. Cables must be handled with extreme care to avoid
damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the
connector. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing the
cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being
removed or replaced.
Cables
Use the following precautions when handling cables to avoid damage to the cable or computer:
●

●
●
Always handle cables by their connectors.
Avoid bending, twisting, or pulling on the cables.
Apply minimum required force when seating or unseating the cables from their connectors.
Place the cables 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.
CAUTION: When servicing these computers, ensure that cables are placed in their proper
location during the reassembly process. Improper cable placement can cause severe damage to
the unit.
