SECTION 6 Managing Batteries and Power ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ Introduction 62 Practical Battery Tips 62 Conserving Power and Extending Battery Life Low Battery Warnings 66 67 Power-saving Features 67 Removing and Replacing Batteries 69 Charging Batteries 71 Battery Storage and Care 72 Disposing of Batteries 73 T M W E K N O W T H E R O A D
X-C 6250 Pro (300) NT Users Manual Introduction The mobile computer uses a Nickel Metal Hydride (NiMH) battery. This section provides some important information about these types of batteries and ways to extend their life. Practical Battery Tips Tip 1. Getting the most from your battery • Your battery will last longer during the day if it is used and charged between 10°C and 30°C (50°F and 86°F). • Charge the battery nightly where the temperature will remain around 20°C (68°F).
Section 6. Managing Batteries and Power • Unplug peripherals and remove peripheral and network PC Cards when you are not using them. • Certain devices and PC cards will prevent the unit from suspending when they are inserted into a PC card slot on the unit. If they are not required, and the unit will be used intermittently, the battery will drain unnecessarily. They should be removed when not needed. To do this, one must first shutdown the unit, remove the card, and then reboot.
X-C 6250 Pro (300) NT Users Manual To prevent possible damage to the battery, the system will not allow a charge if the battery temperature is above 50°C (122°F) or below 5°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 when the Power Profiler application shows a full gas gauge even though the external power indicator light may still be blinking.
Section 6. Managing Batteries and Power In cold conditions • When using a battery in cold conditions, the battery capacity can drain 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 allow a charge if the battery temperature is below 5°C (41°F), such as in a closed, unattended vehicle during the winter. • If possible, charge the battery in a location with a moderate temperature of around 20°C (68°F).
X-C 6250 Pro (300) NT Users Manual Conserving Power and Extending Battery Life Follow these guidelines to get the most use from your batteries and extend their life. • Turn off your computer by pressing FN+OFF whenever you are not using it. • Make sure your system suspends automatically. PC Cards, custom applications, or modified system settings can affect this. • Unplug peripherals and remove peripheral and network PC Cards when you are not using them.
Section 6. Managing Batteries and Power Low Battery Warnings When the battery becomes low, the mobile computer beeps and the battery indicator light blinks. If you are running Windows, a warning message also appears on the screen periodically. Unless you connect external power or replace the battery within a reasonable time, the system turns off the computer automatically.
X-C 6250 Pro (300) NT Users Manual Hard Disk Standby To conserve power, the hard disk switches to standby mode after a period of inactivity and resumes when it detects activity. Display To conserve power, the system turns off the display when the computer enters suspend mode. It automatically turns on when the computer is turned back on. Backlight The display backlight can be turned on to make information on the screen easier to read in low-light situations.
Section 6. Managing Batteries and Power MaxBright MaxBright is a feature available on 10.4-inch color display that intensifies the backlight to its maximum brightness. Pressing FN+F1 toggles MaxBright on and off. The system automatically turns off MaxBright after a period of inactivity, and this time-out setting can be changed in the System Configuration Utility (SCU). See Section 5, Customizing Settings, for information about accessing the SCU. Cycle Discharging later in this section.
X-C 6250 Pro (300) NT Users Manual To remove and replace the battery 1 Turn off the computer by pressing FN+OFF, and then locate the battery door in front of the keyboard. 2 Push the two battery door latches down to unlatch the door and slide it away from the unit (C). 3 Grasp the ribbon and pull up on the battery to remove it. 4 Align the battery connectors and place a new battery in the computer (D). 5 Replace the battery door and make sure it is securely latched.
Section 6. Managing Batteries and Power Charging Batteries To maintain power and prevent data loss from a low battery, charge the battery daily. You can use several external power or charging devices approved for use with the mobile computer. The AC adapter comes with your computer, but you also can use other optional devices such as the vehicle adapter, the stand alone charger, or the vehicle cradle. See Section 8, Optional Equipment and Accessories, for more information about this equipment.
X-C 6250 Pro (300) NT Users Manual Leave the display tilted open and allow unrestricted airflow while the battery is charging. This allows excess heat to escape from the battery compartment and helps prevent the battery from overheating. The battery starts fast charging automatically, and the external power indicator light blinks while the battery is charging. At moderate temperatures, around 70 degrees Fahrenheit, the battery will complete charging in 3 to 4 hours.
Section 6. Managing Batteries and Power Disposing of Batteries WARNING The mobile computer is powered by a rechargeable Nickel Metal Hydride (NiMH) battery. Disposing of the battery improperly can cause serious personal injury. Do not crush the battery or place it in a fire. The battery is recyclable and, under various state and local laws, it may be illegal to dispose of it into the municipal waste stream. Check with your local solid-waste officials for details on recycling options or proper disposal.

Appendix B.
X-C 6250 Pro (300) NT Users Manual Applications My application locks up, acts strangely, or produces an NT blue screen (crash screen for monochrome displays) • If youve tried to resolve the problem other ways and your application still doesnt respond, you may need to restart your computer as described below. CAUTION Restarting your computer may corrupt files or data. Reset the computer by holding down both mouse buttons for at least 10 seconds and then releasing the buttons.
Appendix B. Troubleshooting Applications Communications programs such as HyperTerminal or Procomm Plus dont seem to work or they lock Windows • If you are using the internal modem, be sure to specify COM3 as the communications port. • When you first try to use HyperTerminal or similar application, the system responds with a message asking if you want to install the modem. Answer Yes to this question and follow the instructions on the screen to install it.
X-C 6250 Pro (300) NT Users Manual Batteries The battery does not charge • To prevent possible damage to the battery, the system will not allow a charge if the battery temperature is extremely hot or cold (such as in a closed, unattended vehicle). If possible, charge the battery in a location with a moderate temperature of around 20°C (68°F). • Keep the display tilted open and allow unrestricted airflow while the battery is charging so excess heat can escape and prevent the battery from overheating.
Appendix B. Troubleshooting Batteries The batteries take much longer than three hours to charge • Under moderate temperatures, about 21°C (70ºF), the computers battery takes 3 to 4 hours to completely charge. Under extremely cold or hot temperatures, however, the battery can take up to 16 hours to fully charge. The batteries dont last very long • Over time, your battery may develop memory effect. This occurs when the battery is partially discharged and recharged repetitively without full discharge.
X-C 6250 Pro (300) NT Users Manual Batteries The gas gauge reads full, but the indicator light is still blinking • If you charge your battery daily, rely on the gas gauge reading to determine battery capacity.
