First Low-Battery Warning
First Low-Battery Warning
Low-battery operation differs depending on your operating system:
For Advanced Configuration and Power Interface (ACPI) compliant systems such as Windows® 98, Windows 2000, and Windows Me, Dell Inspiron B130 Battery, you can configure low-battery notifications and actions through the Power Management Properties window (Windows 98) or the Power Options Properties window (Windows 2000 or Windows Me).
For Advanced Power Management (APM) compliant systems such as Windows NT, the first low-battery warning occurs when the battery has about 20 minutes of life remaining under current conditions and the computer is not connected to an electrical outlet. The first low-battery warning is indicated in three ways: a battery warning icon appears on the screen, a triple beep sounds from the speaker, and the battery status indicator (see Figure 1) flashes amber.
NOTICE: When you receive a low-battery warning, save your work immediately. Then replace the battery or connect your computer to an electrical outlet.

Second Low-Battery Warning
Low-battery operation differs depending on your operating system:
For ACPI compliant systems such as Windows 98, Windows 2000, and Windows Me, you can configure low-battery notifications and actions through the Power Management Properties window (Windows 98) or the Power Options Properties window (Windows 2000 and Windows Me).
For APM compliant systems such as Windows NT, the second low-battery warning occurs when the battery has about 15 minutes of life remaining under current conditions and the computer is not connected to an electrical outlet. The second low-battery warning is indicated in three ways: the battery status indicator (see Figure 1) turns solid amber, a triple beep sounds from the speaker, and the computer enters suspend mode immediately after the beep.
If no further input/output (I/O) activity occurs within a few seconds, Dell Inspiron 9300 Battery, Dell Inspiron 9400 Battery, Dell Inspiron B120 Battery, Dell Inspiron B130 Battery,the computer enters S2D mode. If the computer has no S2D file, it stays in suspend mode, in which it can preserve data for several hours.
If the computer is already in suspend mode when the second low-battery warning occurs, the computer enters S2D mode immediately. Dell Inspiron B120 Battery, If S2D mode has been disabled, the computer reenters suspend mode.
NOTICE: To avoid losing data and possibly corrupting data areas on your hard-disk drive, save your work immediately after a second low-battery warning. Then connect your computer to an electrical outlet, or place the computer in suspend (or standby) mode. If the battery runs completely out of power, the computer turns off without properly closing any open files.

Detecting Battery Problems
A battery problem may prevent the battery from being charged to its full potential and can lead to unpredictable operation. To obtain a new battery, call Dell or access the Dell World Wide Web site at http://www.dell.com.
To avoid installing a defective battery in your computer, first check the battery's charge, indicated by the battery charge indicators on the battery itself, by pressing the battery test button (see Figure 3).
NOTE: If the battery has 0 (zero) percent charge, you cannot use the battery test button to check the battery's capacity. The battery charge indicators will not light if the battery is completely drained.
--------------------------------------------------------------------------------
Battery Disposal
CAUTION: Do not puncture or incinerate the battery.
NOTE: To purchase a new battery, call Dell or access the Dell World Wide Web site at http://www.dell.com.
Your computer system uses both a lithium-ion battery pack and a nickel-metal hydride (NiMH) coin cell battery.Dell Inspiron 9400 Battery, For instructions about replacing the lithium-ion battery pack in your computer, see "Replacing the Battery." The NiMH battery is a long-life battery, and it is very possible that you will never need to replace it. However, if this battery ever needs to be replaced, the procedure must be performed by an authorized service technician.
Do not dispose of these batteries along with household waste.Dell Inspiron 9300 Battery, Dell Inspiron 9400 Battery, Dell Inspiron B120 Battery, Dell Inspiron B130 Battery, Contact your local waste disposal agency for the address of the nearest battery deposit site.

About Battery Power
You automatically conserve battery power each time you connect the computer to an electrical outlet. The battery is even being recharged when you use AC power. The battery's life expectancy is largely determined by the number of charges it receives, so use an electrical outlet to run the computer whenever possible.
You can customize power management by individually controlling the computer's power conservation features. These features reduce power consumption by monitoring application programs and computer devices for inactivity and slowing down or stopping some of the computer’s internal devices.
NOTES: When you use power conservation features, you often trade some of the performance of the computer for increased battery operating time. For example, if you turn off the hard-disk drive, you may experience a delay the next time the computer tries to access the hard-disk drive.
Other power conservation features, such as suspend (or standby) mode, stop almost all system activity. They allow you to maximize power conservation when your work is interrupted.
Experiment with power conservation features to achieve the optimum power conservation for your work environment.

Battery Auto-Learning Utility
The Battery Auto-Learning utility, available through the system setup program, helps maintain battery gauge accuracy on your Latitude L400 computer.
The utility allows the battery to learn its full charge capacity. Dell Inspiron 9300 Battery,The computer uses the full charge capacity value to determine the length of time that the battery can operate on a single charge. An incorrect full charge capacity value causes the computer to report the remaining battery life incorrectly to the operating system, which may result in shorter than expected battery life.
NOTE: The full charge capacity may vary among batteries and may decrease as the battery goes through multiple charge and discharge cycles.
To run the utility, use the Run Battery Learning option on the Power screen of the system setup program.
NOTES: The learning process may take up to six hours to complete. You can stop the process at any time by pressing <Esc>.
Use the utility if you suspect that the accuracy of the gauge is incorrect.Dell Inspiron 9300 Battery, Dell Inspiron 9400 Battery, Dell Inspiron B120 Battery, Dell Inspiron B130 Battery, However, do not run the utility more than once every two monthsrunning the utility more often reduces the service life of the battery.

Turning On the Computer
To turn on the computer, press the power button.
NOTES: If your computer's operating system is "locked up"—that is, it does not respond to commands—press and hold down the power button for at least five seconds to turn off the computer.
If the operating system locks up and does not respond to the power button, you can restart the computer using the reset switch on the bottom of the computer. To do so, straighten a paper clip and press it into the reset switch access hole for about one second.
