74X-C 6250 Pro Users Manual79-0003-003 22 October 1999IntroductionThe mobile computer uses a Nickel Metal Hydride (NiMH) battery. Thissection provides some important information about these types ofbatteries and ways to extend their life.Practical Battery TipsTip 1. Getting the most from your battery•Your battery will last longer during the day if it is used and chargedbetween 10°C and 30°C (50°F and 86°F).•Charge the battery nightly where the temperature will remain around20°C (68°F).•Set up your system to automatically suspend (turn off) while thebattery is charging.This can be done by enabling the Suspend on AC Power optionunder the Power, Suspend/Resume Control menu in the SystemConfiguration Utility (SCU). This allows the system to automaticallysuspend while it is connected to external power.•Use the Battery Maintenance application (located in the computertools folder) to deep cycle discharge your battery. Deep cycling yourbattery reconditions it and eliminates memory effect. Follow theseguidelines when deep cycling:- Deep cycle your battery when requested, which may be as oftenas 3 months, depending on usage.- For the best conditioning, deep cycle the battery where thetemperature will remain around 20°C (68°F). - Leave the display tilted open and allow unrestricted airflow soexcess heat can escape from the battery compartment andprevent the battery from overheating.- Consider running the deep cycle process over a weekend becauseit can take up to 40 hours to complete.
75Section 7. Managing Batteries and Power79-0003-003 22 October 1999•The indicator light may read fully charged, but this does notnecessarily guarantee sufficient capacity. Use the Battery Statusapplication periodically to check your batterys capacity, and thenrecondition it as needed.•Even the best maintained batteries eventually need to be retired.They simply degrade from continuous use. Consider replacing yourbattery if you are not getting the usage you need from it afterperforming a deep cycle discharge.Tip 2. Conserving power and extending battery life•Turn off your computer by pressing FN+OFF whenever you are notusing it.•Make sure your system suspends automatically. PC Cards, customapplications, or modified system settings can affect this.•Unplug peripherals and remove peripheral and network PC Cardswhen you are not using them.•If you have a monochrome display, turn off the backlight when youdo not need it.•If you have a 10.4-inch color display, turn off MaxBright when youdo not need it.•Use the SCU to set power management options at levels that willconsume the least amount of battery power (see Section 5,Customizing Settings, for more information).•Use the AC adapter or vehicle adapter whenever possible.•Avoid exposing batteries to extremely hot or cold temperatures forlong periods.•The mobile computer display does not require a screen saver. Usingscreen savers consumes valuable battery power and is discouragedunless the unit is connected to external power and an externalmonitor.•Deep cycle discharge your battery when requested, which may be asoften as 3 months, depending on usage by using the BatteryMaintenance application.•Store the battery within the recommended temperature range: 10°Cto 30°C (50°F to 86°F).
76X-C 6250 Pro Users Manual79-0003-003 22 October 1999Tip 3. If your battery is new or has not been used forseveral weeksFollow these guidelines to deep cycle discharge the battery andcondition it.•Deep cycling the battery up to four times in succession may increaseits capacity. You may want to do this over consecutive weekendssince each deep cycle process can take up to 40 hours. After thisinitial conditioning, maintain battery capacity by deep cycling whenrequested, which may be as often as 3 months, depending on usage.•For the best conditioning, deep cycle the battery where thetemperature will remain around 20°C (68°F).Tip 4. Determining when your battery has finishedcharging•Under normal circumstances, your battery is finished charging whenthe external power indicator light stops blinking and remains solid.To prevent possible damage to the battery, the system will not allowa charge if the battery temperature is above 50°C (122°F) or below5°C (41°F), such as in a closed, unattended vehicle. In this case,your battery may not be fully charged.•If you charge your battery every night, it is finished charging whenthe Battery Status application shows a full gas gauge even thoughthe external power indicator light may still be blinking.If your battery is new, or if you have not used it for a week or more,the gas gauge may be inaccurate because the battery naturallydischarges over time. In this case, wait until the external powerindicator light stops blinking and remains solid.
77Section 7. Managing Batteries and Power79-0003-003 22 October 1999Tip 5. How your battery behaves in warm and coldconditionsIn warm conditions•When using a battery in warm conditions, the battery capacity willdrain faster. In general, as the temperature rises, it is possible for thebattery to drain 20 percent faster at 40°C (104°F) and 50 percentfaster at 45°C (113°F). •To prevent possible damage to the battery, the system will not allowa charge if the battery temperature is above 45°C (113°F), such asin a closed, unattended vehicle during the summer.•If possible, charge the battery in a location with a moderatetemperature of around 20°C (68°F). The battery wont last as longduring the day if charged at higher temperatures because heat slowsdown the batterys chemical reactions. Also, if the battery becomestoo hot while charging, the charge mode automatically switches fromFast Charge to Slow Charge. Slow Charge takes much longer to finishcharging the battery.•When charging the battery, leave the display tilted open and allowunrestricted airflow so excess heat can escape from the batterycompartment and prevent the battery from overheating.In cold conditions•When using a battery in cold conditions, the battery capacity candrain 30 percent faster at 4°C (39°F) and 70 percent faster at -11°C(19°F).•To prevent possible damage to the battery, the system will not allowa charge if the battery temperature is below 5°C (41°F), such as in aclosed, unattended vehicle during the winter.•If possible, charge the battery in a location with a moderatetemperature of around 20°C (68°F). The battery wont last as longduring the day if charged at lower temperatures because cold slowsdown the batterys chemical reactions.
78X-C 6250 Pro Users Manual79-0003-003 22 October 1999Tip 6. Preventing data lossHow to prevent data loss when removing the battery or storingyour computer•You can lose data if you remove the battery while the computer isoperating on battery power. To prevent this, turn off the unit bypressing FN+OFF before you remove the battery.•The computer is equipped with enough internal backup power tomaintain memory contents for about 5 minutes each time youexchange batteries. Be careful not to exceed this 5 minute limitwhen you replace the battery.•If you plan to store your computer for more than 30 days, exitWindows to save data to the hard disk, and then press FN+OFF toturn off the computer. Remove the battery before storing thecomputer.Tip 7. Returning batteries for service•When shipping batteries, use non-static packing material to reducethe possibility of static discharge. Placing the battery in a non-staticbag is ideal; however, wrapping the battery in paper or newspaper isalso acceptable.•Contact your supervisor or your organizations help desk for correctshipping procedures and information.Tip 8. For more information•The Battery Status and Battery Maintenance applications providebattery troubleshooting information. From the Help menu for eachapplication, choose Contents (or Help Topics), and then chooseTroubleshooting, followed by Common Solutions to CommonProblems.

108X-C 6250 Pro Users Manual79-0003-003 22 October 1999Surge ProtectionA large number of computer and high technology equipment damage isdirectly related to AC power and telephone line problems. Theseproblems can include surges, spikes, noise, interference, and weather-related problems, which in turn can cause glitches, hang-ups, crashes,performance slow downs, and down time with computer equipment.The market is flooded with hundreds of AC power line surge suppressorsadvertising high performance surge protection; only a few of themactually provide adequate protection. This section provides guidelines for selecting a quality surge suppressorto be used with your mobile computer, and it helps identify a fewsources for products with acceptable performance.Selecting the Right Surge ProtectionConsider the level of quality you need when selecting a surgesuppressor. This depends on factors such as surge environment, thetype of equipment to be protected, and the quality of the electricalwiring and service. Surge EnvironmentSurge environment refers to the damage potential from electrical surgesin a particular geographical area. A high quality suppressor should beused if there is frequent lightening activity in the area and the locationservice is fed by overhead utility poles. An example of a high surgeenvironment would be Florida; a low surge environment might be NewYork.Type of Equipment to be ProtectedIf the computer is equipped with a modem, the modem should also besurge protected. Protecting the power line without protecting themodem line provides only partial protection.
109Section 9. Optional Equipment and Accessories79-0003-003 22 October 1999Quality of Electrical Wiring and ServiceWiring should be up to current NEC standards and have verified goodAC grounds. It is important that your computer system be plugged intoa grounded AC outlet when charging and that all peripherals connectedto your system reference the same AC ground.Selecting the Right EquipmentThere are a number of companies that sell quality surge suppressorssuch as Sutton Designs, APC, and Panamax. When you are looking for asurge suppressor, consider these things.•Expect to pay at least $50 for a good quality surge suppressor.•The surge suppressor should be a UL 1449, 497, and 1283 listedfor surge suppression, modem surge protection, and RFI/EMI noisefiltering respectively.•The surge suppressor should have diagnostic LEDs that verify goodAC ground, proper wiring, and proper surge operation. Lighted on/offswitches are not recommended since they can produce electricalnoise.•The Joule ratings should be a minimum of 480 Joules for the ACsurge circuit.•The Joule ratings should be a minimum of 240 Joules for themodem.•The modem surge circuit should present low capacitance to themodem line or it will slow the transmission rate. Capacitance shouldbe specified at less than 50 picofarads.•Quality surge suppressor manufacturers generally offer a lifetimewarranty.•Consider obtaining a protected equipment coverage policy whichinsures the equipment in the event of surge damage.•The devices that will be attached to the computer also need to besurge protected.

Under extremelycold or hot temperatures, however, the battery can take up to 16hours to fully charge.The batteries dont last very long•Deep cycle discharge the battery using the Battery Maintenanceapplication. If your battery is new or has not been used for severalweeks, deep cycle discharging the battery over two or threeconsecutive weekends may substantially increase its capacity.•As your battery ages, the maximum capacity that it can holdnaturally decreases, and even the best maintained batterieseventually need to be retired. Consider replacing the battery if youare not getting the usage you need from it.•You may have a defective battery. Check the battery condition withthe Battery Status application. Generally, a battery should bereplaced when it charges to less than 80 percent of capacity.The charging light doesnt flash•Verify that a battery is installed in the unit.•This may indicate that the charging process terminated.

Ambient temperatureis not used for charge termination criteria.The gas gauge reads full, but the indicator light is still blinking•If you charge your battery daily, rely on the gas gauge reading todetermine battery capacity. The charge mode may have switchedfrom Fast to Slow because the battery became too hot. The chargingprocess is trying to put a little more capacity into the battery;however, external power can be removed because the battery isvirtually full.•If your battery is new or has not been used for several weeks, rely onthe indicator light to determine when the battery is fully charged.The gas gauge is unreliable in these cases; it may read 100 percent,but the actual capacity is only 10 percent.My battery seems to have less and less capacity•To keep your battery at optimum performance, perform a deep cycledischarge every 2-1/2 to 3 months using the Battery Maintenanceapplication.•Over time, your battery may develop memory effect. This occurswhen the battery is partially discharged and recharged repetitivelywithout a full discharge. A partial or shallow discharge means thatyou use less than 50 percent of its capacity before charging. Deepcycle discharge the battery using the Battery Maintenanceapplication to help prevent memory effect.•If your battery is new or has not been used for several weeks, deepcycling it up to four times in succession may increase its capacity.You may want to do this over consecutive weekends since each deepcycle process can take up to 40 hours. After this initial conditioning,maintain battery capacity by deep cycling at the recommendedfrequency.
