2 Using Battery Power The primary difference between using battery power and AC power is the limited time you can operate under battery power before you must recharge. This chapter covers charging the battery and maximizing the time between charges and assumes that you installed and charged the battery as directed in the Quick Start instructions.
Guidelines for Battery Use Caution: Never dispose of exhausted batteries in a fire. The battery should be handled carefully to ensure maximum life. In particular: Do not drop the battery or subject it to shocks. Do not expose the battery to direct sunlight, moisture, chemicals, or temperature extremes.
Switching to Battery Power To switch from AC power to battery power: 1. If the computer is turned on, turn the computer off or press Standby to put the computer in standby mode. When in Standby, the screen goes dark, and the Power indicator turns amber 2.
Responding to Low Battery Conditions When the battery has 5% to 10% of its charge remaining, the BAT indicator starts to blink. The low-battery alarm (an Intermittent chirping tone) may also begin to sound if enabled in Setup.
Responding to Low Battery Conditions If you are in Windows, double-click on the Shutdown icon to exit all active applications as well as Windows. Press Standby to put the computer into sleep mode whenever you are not actively using the computer. Turn off the computer if it does not need to be active.
Responding to Low Battery Conditions Hint The computer has two ways to give you advanced warning that the battery is nearing depletion. • As the charge in the battery is reduced, peak power loads, such as disk accesses, can cause the BAT indicator to indicate low battery power for short periods of time.
Recharging the Battery Caution: Never recharge the battery differently from the procedure described in this manual. The following procedure is acceptable under most circumstances. 1. Install the battery pack in your computer (if not already installed).
Installing and Removing the Battery Pack Removing the Battery Pack 1. Turn off the computer, and disconnect the AC Adapter and any other external device connectors. Note: You cannot remove or install a battery pack with the unit powered on. You must turn power off to the unit.
Installing and Removing the Battery Pack Installing the Battery Pack 1. Turn of f the c omp ute r, disco nn ec t th e AC A dapte r and any o ther external devices. 2. Clo se the d isplay , and care f ully lay th e c o mpute r ups ide do w n on a padded surface.
Conserving Battery Power The following tips can help you prolong the lift of a battery charge: Keep the LCD at the lowest comfortable brightness level. Reducing brightness even a small amount can significantly reduce power consumption and increase operating time.
Conserving Battery Power Disconnect or turn off external options that you are not using. Use one of the Setup programs to disable ports you are not using. Use only Texas Instruments options, which are designed to operate with the least possible energy consumption.
Conserving Battery Power The total time elapsed to discharge a fully-charged battery The time between activation of the BAT Indicator and computer shutdown because of insufficient power For the Power .
Conserving Battery Power Setting the Alarm Delay You can set the low-battery alarm to activate later than the flashing BAT indicator. The delay is based on a percentage of the charge remaining after the BAT indicator comes on. The default is 50 percent.
3 Using Software This chapter describes the software supplied with the computer and how to configure application software to run on the computer. Contents Using Supplied Software ........................................................................
