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.

Handle itwith the normal care required by any sophisticated electronicequipment, and the computer will provide reliable service even underharsh field conditions.Follow the guidelines below to care for your unit.If You Have a Touch ScreenHard Drive Care and HandlingThere are two hard drive options for the mobile computer: a shock-mounted 2.5-inch hard drive and a PC Card Type III hard drive. All harddrives contain media for data storage in the form of a rotating disk,read/write head(s), a motor, and electronics for interfacing and control.Each hard drive type can be susceptible to damage from severe shockand other stressful environmental impacts. The degree of susceptibilityto damage is directly related to the individual hard drive and mountingsystem employed. When reading or writing to the hard disk, the head is flying on a thinlayer of air, micro-inches above the disk. A shock can cause the read/write head to contact the spinning disk, resulting in immediate loss ofstored data and possible physical damage to the disk. It could also
117Section 11.  Maintenance and Storage79-0003-003   22 October 1999create loose debris in the drive enclosure that may cause progressivedamage over time.To reduce exposure to high operating shocks, the mobile computer usespower modes for the hard drive that prevent the read/write heads frombeing positioned over the disk when it is not being used: idle mode andstandby mode.You can reduce the risk of damage to the hard drive and increase thereliability of the hard drive and data integrity by following therecommendations below.Internal Hard Drives•Do not intentionally drop the computer. The unit is designed towithstand the day to day rigors of the mobile environment andprovide years of reliable service. The useful life of the product can beenhanced by not intentionally abusing it.•Use the power management feature control in the SystemConfiguration Utility (SCU). Power management conserves power butalso ensures that the read/write heads are unloaded and the harddrive is spun down within the time specified.•Whenever possible suspend the unit by pressing FN+OFF beforemoving it from one location to another. This will unload the read/write heads and spin down the disk.•Maintain the environmental seal of the computer by keeping the PCCard door closed and latched. Also avoid exposing the unit toextreme temperatures or moisture when the PC Card door is open.•Periodically backup or archive important files and data.
