Charging the Battery Pack Outside of Normal
Operating Conditions

Under normal operating conditions fast charging of a battery pack begins when the power cord is connected to the computer and plugged into an electrical outlet. However, fast charging may not occur immediately if one of the following conditions exist:

•	The battery pack temperature is outside the normal operating range of 50°F to 104°F (10°C to 40°C).

•	The battery pack is below normal discharge levels, which can occur after an extended period of nonuse (approximately 30 days or more) such as with new battery packs.

When you plug in the power cord, the battery light on the front of the computer comes on, although fast charging may not occur right away. If the battery pack is not within normal temperature and charge level, it trickle charges until normal operating conditions are reached, which may take several minutes to an hour.

Maximizing Battery Life

Battery operating time varies depending on the system components, options, and applications being used. You can increase battery operating time by as much as 50 percent by controlling the energy required by the computer and the energy stored in the battery pack.

 NOTE:  The display, processor, and hard drive components use the majority of battery power.

Optimize battery pack energy by:

•	Selecting the High level of power conservation.

•	Putting the computer into Standby, Hibernation, or turn it off when you are not using it.

•	Reducing the brightness on the display. and selecting a shorter screen save.

•	Completely discharging and recharging the battery pack at least every 60 days.

•	Avoiding unnecessary fast charge cycles, which reduce the life of the battery.

•	Keeping a battery pack in the computer when you're using it with external power. This supplies the battery pack with a constant trickle charge.

•	Disconnecting any external equipment that does not have its own power source. Any external equipment that is connected to the computer drains the battery pack.

•	Exiting modem programs when not in use.

•	Removing PCMCIA cards or turning off when not in use.

•	Storing the battery pack in a cool, dry place when it's not in use. The recommended storage temperature range for the battery pack is from -20 [image] C to 30 [image] C (-4 [image] F to 86 [image] F). High temperatures cause a battery pack to lose its charge more quickly and reduce battery pack life.

•	Use a disk cache utility, such as the MS-DOS SMARTDRV command, or a virtual disk, such as the MS-DOS RAMDRIVE device driver, to reduce hard disk use.

How Does Power Conservation Work?

The Power Management and Hibernation utility lets you fine tune power conservation to best suit your needs. Power Management extends battery operating time.

Power conservation monitors most of the computer components, such as the hard drive, processor, and display. When a component is inactive for a specified period of time (called a timeout), it shuts off or slows down to conserve battery power. For example, the timeout preset for hard drive inactivity is two minutes. If a software application does not access information on the hard drive for two minutes, the drive shuts down until it is accessed again.

The following power conservation functions are available from Windows or DOS:

•	Conservation Levels and Settings

•	Standby

•	Hibernation

•	Timeout

•	Warning Beep

Related Topics:

Identifying a Low Battery Condition

Advanced Power Management


What is a Timeout?

A timeout is a specified period of system or component inactivity. After this period, power conservation shuts down the system or component to save battery power. For example, the hard drive component default timeout is 2 minutes. Therefore, if an application does not access information on the hard disk for 2 minutes, the drive shuts down until it is accessed again.

Timeouts work with power conservation to conserve battery power. You can save battery power by:

•	Using timeouts that correspond with the preset medium (default) or high level of power conservation.

•	Using the custom level of power conservation to set your own timeouts so that they work more efficiently with your applications.

What is Advanced Power Management?

Advanced Power Management is a specification that defines an environment when applications, operating systems, and the system BIOS work together to reduce power consumption. For the most part, APM runs behind the scenes saving power without your knowledge.

For example, APM idles the microprocessor when applications are idle and between keystrokes. An occasional message may be displayed on the screen describing various conditions that may occur, such as low power.


What are the Levels of Power Conservation?

The four levels of power conservation are:

•	Medium (default)

Provides a balance between system performance and battery operating time.

•	High

Provides maximum power conservation. Select this level if you need more battery life and don't mind shorter timeouts and a dimmer display.

•	None

Provides maximum battery drain because power conservation is turned off. Recommended for discharging the battery pack.

•	Custom

Lets you set the timeouts so that the computer works efficiently in your environment.

 NOTE:  The Custom level default settings are the same as the Medium level until you set your own values.

What is Standby?

Standby is a reduced power condition during which most of the components (e.g., display, hard drive, processor, keyboard) shut down after a period of system inactivity called a timeout. It works when the computer is running on battery power or AC power. Standby can also be used as an instant-on feature.

To conserve energy, you can use the Standby feature when the power cord is attached. Press the standby button to initiate Standby.

With a fully charged battery, the computer can be left on and in Standby for up to 168 hours providing you use the instant-on capability. When you exit Standby, your information returns to the screen at the point where Standby was initiated. No information is lost.

If the computer is left in Standby and reaches a critical low battery condition, the system initiates Hibernation, saves your information to the hard disk, and the computer turns off. When you turn on the computer, your information returns to the screen at the point where Standby was initiated. No information is lost.

Write-Protecting a Diskette

When a diskette is write-protected, the information stored on it can be read by the computer, but it cannot be changed.

Before you begin to use any diskettes that come with a new software program, it is always a good idea to make backup copies to use every day and to write-protect the originals to ensure that you'll always have access to the software.

	Each 3.5-inch diskette has a sliding write-protect tab [image]. To write-protect a diskette, slide the tab on the corner of the diskette until the window is open.

Making Backup Diskettes

Two utilities, SAVEALL and LOADALL, are preinstalled on the hard drive. SAVEALL backs up the C drive onto diskettes. LOADALL restores the software from these diskettes to the hard drive.

To help you remember to create backup diskettes, the system automatically prompts you to run a backup program the second time you turn on the computer. You can create the backup diskettes at that time or choose to have the system prompt you every time it is restarted to make the backup diskettes.

The SAVEALL utility can be run using either formatted or unformatted diskettes. If the diskette is unformatted, the utility formats the diskette, then proceeds with the backup.

What is Hibernation?

Hibernation is a condition during which all the information in system memory is saved to the hard drive and power to the computer is turned OFF. When you turn on the computer, your information is returned to the screen at the point where Hibernation was initiated, even from within an application. No information is lost. There is no limit to the amount of time the computer can remain in Hibernation since the computer is off. There is no drain on the battery pack.

This feature can also be used as a place marker, conveniently providing a way to mark your place in an application. It is useful when you're making a presentation away from the office. You can do all the preparation in advance, mark your place with Hibernation, and be ready to present as soon as you arrive.

Also, Hibernation is a safeguard feature that saves information should the computer reach a low battery condition while it is left unattended.

Hibernation is automatically enabled on your computer and a file created on the hard disk. The Hibernation file is slightly larger than the amount of memory that is in your computer. Disabling Hibernation and deleting the Hibernation file frees up disk space. However, disabling Hibernation is not recommended.

  CAUTION: If a low battery condition is indicated and you continue to use the computer, the system may not hibernate and unsaved data will be lost.

Initiating Hibernation

Hibernation can be initiated by the system or by the user.

•	System-initiated Hibernation

-	When the computer is on and unattended, and a low battery condition occurs.

-	When the computer is in Standby and a low battery condition occurs.

-	When the Hibernation timeout occurs.

•	User-initiated Hibernation with the Fn key and standby button

When Hibernation initiates, the system:

•	Clears the screen.

•	Saves ALL current information in memory to the hard disk.

•	Turns the computer off.

Related Topics:

Disabling Hibernation


Exiting Hibernation

To resume work after Hibernation is initiated:

•	Turn on the computer.

•	Install a fully charged battery pack or connect an external power source if a low battery condition existed before Hibernation was initiated.

The computer exits Hibernation. The information saved to the hard drive returns to the screen at the point where Hibernation was initiated. The computer recognizes the same trackball or other pointing device you were using when Hibernation was initiated.

 NOTE:  To stop the restoration of the information, press the Fn + Ctrl + Break keys.

Hibernation Utility

This utility, which is preinstalled in the AUTOEXEC.BAT file, provides a way to disable Hibernation from DOS.

You can change the HIBRN8 parameters at the command line. The parameters are:

HIBRN8 [ON] [OFF] [DEL] [n] [STATUS] [/?|HELP|?] [MUTE] [LOWBATT] [STANDBY]

ON	Creates the Hibernation file, enables Hibernation, sets Hibernation timeout to 1 hour.
OFF	Disables Hibernation, but does not delete the Hibernation file.
n	Numerical value between 0 and 15 hours. This value sets how long after Standby that Hibernation initiates. Also, It enables Hibernation and creates the Hibernation file if it does not exist. Half-hour increments are valid. Any decimal value can be accepted and rounded to the nearest valid value.
DELETE	Disables Hibernation and deletes the Hibernation file.
STATUS	Displays a copyright and status of Hibernation.
? or HELP	Displays a command line parameter list.
LOWBATT	Enables Hibernation and creates the Hibernation file if necessary. Hibernation is set to initiate during a low battery condition.
STANDBY	Enables Hibernation and creates the Hibernation file if necessary. Hibernation is set to initiate during Standby, which means that Standby is replaced by Hibernation. Hibernation occurs if you press the standby switch without the Fn key. This is equivalent to 0 hours.

What are the Types of Memory?

The computer uses two types of memory:

•	Random access memory (RAM)

•	Read only memory (ROM)

The computer uses memory as a place to manage the work of the computer as well as a place to work. The computer processor, or "thinking" part of the computer, controls all its operations by:

•	Running the software applications stored on the hard drive.

•	Processing the information you enter.

•	Controlling the input and output of all devices including the keyboard, mouse, disk drives, monitor, modem, and printer.

The space memory occupies in the computer can be divided or mapped into five memory areas - base, upper, high, extended, expanded - each with a different purpose.

Random Access Memory

When you run a software application, the computer reads the program information from the hard drive, copies it into its temporary or random access memory (RAM), then opens the application for you to use. Think of RAM as the computer's office, the place where the computer works. The computer also uses RAM as a place to temporarily store the information you are working on and as a place to carry out the commands issued by the application.

The most important thing to remember about RAM is that it provides temporary storage. Information remains in RAM only as long as power to the computer is turned on. If you load a document into RAM and turn off your computer or experience a power outage, your work is lost. Information that you have saved to a diskette or hard drive remains safe, but any changes that you've made since you last saved your work are lost. That's why you should save your work frequently.

Read Only Memory

How Is Memory Mapped?


Read Only Memory

Read only memory (ROM) is permanent memory and usually housed in a chip or chipset on the computer system board. ROM generally contains information that the computer processor needs to do its job - information about the computer that does not change even when power to the computer is turned off.

For example, the basic input/output system (BIOS) for the computer is typical of information stored in ROM. The ROM BIOS works as a traffic officer for the computer directing the movement of instructions and information between such devices as the keyboard, mouse, monitor, or modem.

In your computer, ROM also contains a set of instructions that direct a series of tests, the Power-On Self-Tests (POST), that run each time you turn on your computer.

Random Access Memory

How Is Memory Mapped?


Base Memory

Base memory is located between 0 and 640 Kbytes and is generally described as conventional memory for the disk operating system (DOS). MS-DOS uses some of this memory in which to operate and the remainder to run MS-DOS applications.

Related Topics:

Upper Memory

High Memory Area

Extended Memory

Read Only Memory


Upper Memory

The upper memory area ranges from 640 to 1024 Kbytes, which is used primarily by system hardware, such the system ROM and video buffers.

Since being able to run several programs simultaneously has become a necessity for many computer users today, certain software utilities and hardware devices have been created that allow MS-DOS to use available sections of upper memory. By using upper memory, more conventional memory is free for use by other programs, such as word processors and spreadsheet programs. On this computer, the LOADHIGH and DEVICEHIGH utilities enable MS-DOS to use upper memory. Refer to your MS-DOS documentation for more information about DOS memory utilities.

High Memory Area

Memory beyond the first megabyte is called extended memory, and the first 64-Kbyte section of extended memory is called the high memory area.

When used for portions of system files, the high memory area frees conventional memory for other software programs. The HIMEM.SYS utility manages this memory for MS-DOS. Refer to your MS-DOS documentation for more information about DOS memory utilities.

Extended Memory

Memory beyond the first megabyte is called extended memory. Its first 64-Kbyte section is called the high memory area, and the rest commonly referred to as extended memory.

Because extended memory has a higher address range than most MS-DOS applications, such applications generally cannot use extended memory. For example, many applications use DOS extenders that allow MS-DOS applications to access extended memory under certain conditions. DOS extenders are often built into memory-intensive MS-DOS applications, such as spreadsheets and desktop publishing systems. The HIMEM.SYS utility manages this memory area. Refer to your MS-DOS documentation for more information about DOS memory utilities.

Expanded Memory

Because expanded memory does not physically reside in system memory address space, a memory manager is required to access it. And then expanded memory can only be accessed through sections of available upper memory using the Lotus/Intel/Microsoft Expanded Memory Specification (LIM EMS) .

Using LIM EMS, MS-DOS applications can access expanded memory through a 64-Kbyte section of upper memory called a page frame. The page frame consists of four 16-Kbyte sections of memory with each section called an EMS page. Mapping memory through EMS pages makes expanded memory available for MS-DOS applications. Memory mapping requires a memory manager, such as EMM386, which was preinstalled with the MS-DOS software on this computer.

What is Cache Memory?

The computer comes standard with 8 Kbytes of integrated cache memory. Certain models have an integrated coprocessor built into the microprocessor.

Cache memory is high-speed static memory that stores the most recently used information in anticipation that it will be needed again by the microprocessor. If information needed by the microprocessor is in the cache memory, it is transferred to the processor at a much faster rate than it would be from system memory, thereby improving overall system performance.
