Introduction

This section covers troubleshooting information for the above
listed Compaq Presario 1600 Series Portable Computers. The
basic steps in troubleshooting include:

1. Follow the Preliminary Steps.

2. Run the Power-On Self-Test (POST).

3. Follow the recommended actions described in the
diagnostic tables, if you are unable to run POST or if
POST displays an error message.

When following the recommended actions in the Sections on
POST and Diagnostic Error Codes perform them in the order
listed. Rerun POST after each recommended action until the
problem is solved and no error message occurs. Once the
problem is solved, do not complete the remaining
recommended actions.

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

The power consumption requirements for PC

NOTE:

Cards vary widely. Some cards drain the battery
pack very rapidly.

Minimizing the Energy Required

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.

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:

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.

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.

Index

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.

Generating Static

The table shows how different activities generate static
electricity and at different electrostatic voltage levels.

Disassembly

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

Index

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:

privacy and legal statement

As each subassembly is removed from the computer, it
should be placed away from the work area to prevent
damage.

Considerations

Preparation
for
Disassembly

Preparing the Computer for Disassembly

1. Disconnect AC power and any external devices.

2. Remove the battery pack.

3. Remove any PC Cards.

IMPORTANT:

The battery pack should be removed before performing any
internal maintenance on the computer.

Index

NOTE:

WARNING: Metal objects can damage the battery pack as well as the

battery contacts in the battery compartment. To prevent damage, do
not allow metal objects to touch the battery contacts. Place only the
battery pack for the Compaq Presario Series Portable Computers into
the battery compartment. Do not force the battery pack into the bay
if insertion does not occur easily.

CAUTION: Do not crush, puncture, or incinerate the battery pack. Do

not open a battery pack, as this damages the pack, makes it
unusable, and exposes potentially harmful battery components.
There are no field-serviceable parts located inside the battery pack.

The Compaq Presario Series Portable Computers have several screws
of various sizes which are not interchangeable. Care must be taken
during reassembly to ensure that the correct screws are used in their
correct location. During removal please keep respective screws with
their associated sub-assembly.

Cables and Connectors (main page)

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

In order to gain access to the cables, you must first remove the Battery

NOTE:

Pack and the Palmrest Cover with Touch Pad. Those steps are covered in the

Removal Sequence listed to the left.

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.

Removing a ZIF Cable

The computer uses a zero insertion force (ZIF)
connector for the keyboard cable to the system

lift both corners of the ZIF connector and slide
simultaneously with constant light force.

A ZIF connector and its attached
cable can be easily damaged.
Handle only the connector slide
