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 |
|

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

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.
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
NOTE: 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.
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.

Removing a ZIF Cable
The computer uses a zero insertion force (ZIF) connector for the keyboard cable to the system board. To remove a cable from a ZIF connector, lift both corners of the ZIF connector and slide simultaneously with constant light force.
CAUTION:
CAUTION:
A ZIF connector and its attached cable can be easily damaged. Handle only the connector slide when removing or replacing a cable. Never pull or twist on the cable while it is connected.
When servicing this computer, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can damage the computer.
