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:
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:
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.
1.
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.
2.
Your battery is re- conditioned.3.
Plug in the AC adapter and begin using the computer.4.
The table below shows the approximate battery pack charge times:
Approximate Battery Charge Time
Computer On Line Off Line
NiMH Battery Pack 4.0 hours premature
termination
2:00 hrs
Li ion Battery
Pack
4.5 hours premature
termination
2:50 hrs
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.

Electrostatic Discharge
A sudden discharge of static electricity from a finger or other conductor can destroy
static-sensitive 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.

Cables & 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.
