Battery Pack Operating Time

This appendix covers the following information concerning battery packoperating time:

q Increase battery pack operating timeq Conditioning a battery packq Disposal of a used battery pack

I n c re a s in g B a t t e ry Pa c k O p e ra t in g T im e

Battery pack operating time differs depending on several variables. To avoidunnecessary replacement, consider the following variables when determininghow long a charged battery pack should last:

q Power management settings

q Hardware configuration

q Software applications

q Installed options

q

Display brightness

q Hard drive usage

q Changes in operating temperature

q Type and number of installed PC Cards

NOTE: The power consumption requirementsfor PC Cards vary widely. Some cardsdrain the battery pack very rapidly.

Battery pack operating time can be increased by as much as 50 percent bycontrolling the energy required by the computer and the energy stored in thebattery pack.

Electrostatic Discharge

A sudden discharge of static electricity from a finger or other conductor candestroy static-sensitive devices or microcircuitry. Often the spark is neitherfelt nor heard, but damage occurs. An electronic device exposed toelectrostatic discharge (ESD) may not be affected at all and will workperfectly throughout a normal cycle. Although, it may function normally for awhile, then degrade in the internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but inmany cases, the discharge contains enough power to alter device parametersor melt silicon junctions.

Generating Static

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

S e rv ic e Co n s id e ra t io n s

Listed below are some of the considerations that you should keep in mindduring the disassembly and reassembly of the computer.

T o o l a n d S o f t w a re R e q u ire m e n t s

To service the computer, you need the following:

q Compaq screwdriver kit (Spare Part No. 161946-001)q Torx T-9 screwdriverq 3/16-inch and 5mm nut drivers (for screwlocks and standoffs)q Small, standard screwdriverq Small, Phillips screwdriverq Diagnostics software

S c re w s

The screws used in the computer are not interchangeable. If an incorrectscrew is used during the reassembly process, it can damage the unit. Compaqstrongly recommends that all screws removed during disassembly be keptwith 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 toprevent damage.

Ca b le s a n d Co n n e c t o rs

Most cables used throughout the unit are ribbon cables. Cables must be handled withextreme care to avoid damage. Apply only the tension required to seat or unseat thecables during insertion or removal from the connector. Handle cables by theconnector whenever possible. In all cases, avoid bending, twisting, or tearing thecables, and ensure that the cables are routed in such a way that they cannot becaught or snagged by parts being removed or replaced.

C a b l e s

Use the following precautions when handling cables to avoid damage to the cable orcomputer:

q Always handle cables by their connectors.q Avoid bending, twisting, or pulling on the cables.q Apply minimum required force when seating or unseating the cables from their

connectors.q Place the cables in such a manner that they cannot be caught or snagged by parts

being removed or replaced.q Handle flex cables with extreme care; they can tear easily.

CAUTION:When servicing these computers,

ensure that cables are placed in their properlocation during the reassembly process. Impropercable placement can cause severe damage to theunit.

Z I F Co n n e c t o r s

The computer uses a zero insertion force(ZIF) connector for several cableconnections on the system board. Toremove a ZIF cable from its connector,pull both ends of the ZIF cable guide claspout of the sleeve about 0.05 - 0.1" (1 - 2mm) , then gently slide the cable out .

CAUTION:A ZIF connector and itsattached cable can be easilydamaged. Never pull or twist on thecable while it is connected.

CAUTION: Ensure that cables arereplaced in their proper location.Improper cable placement candamage the computer.
