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.

NOTE:
If the problem is intermittent, check the computer
several times to verify that the problem is solved

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.

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

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.

Prior to conducting any removal and/or replacement procedures, you should review and fully understand
the section titled "

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.

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.
