1.4.3.1Controls and Indicators

The Extensa 57x contains a Power Button and a Status LCD just above the keyboard. All notebook functions (except the power On/Off function) are controlled by keyboard keys in conjunction with the Fn key.

1.4.4Standard Power Features

Notebook power for the Extensa 57x Series Notebook Computers is provided by an AC Adapter and a rechargeable nickel metal hydride (NiMH) battery pack that installs in a power bay near the front of the notebook (right side).

A second lithium ion battery may optionally be installed in the Floppy Drive bay when the Floppy Drive is removed from the Notebook.

All members of the Extensa 57x family feature a power management subsystem (hardware and software) that provides for longer portable operation and protection of files during low battery conditions.

Note: The Nickel Metal Hydride (NiMH) battery requires periodic battery con- n ditioning in order to charge to full capacity. To accomplish this, remove the

AC Adapter and the secondary battery pack (if installed). Allow the notebook to deep discharge. Then, recharge to full capacity. The secondary battery pack is a Lithium-Ion type that does not require conditioning.

General Description 1-7

1.4.5Wireless Connection With Serial Infrared Port

The Extensa Series notebooks are equipped with a Serial Infrared (IR) port that offers wireless communication with a variety of IRDA™ compliant devices made by other manufacturers.

n	Note: Prior to communicating with an external device equipped with a serial
	infrared interface, the appropriate third-party drivers must be installed on
	your notebook.

1.4.6Preloaded Software

All members of the Extensa 57x Notebook family are preloaded with the Windows 95 Operating System. In addition, Extensa 575CD and 575 CDT models come standard with the following application packages installed:

∙

∙

∙

Microsoft™ Works

Quicken SE

Lotus™ Organizer

Microsoft Entertainment Pack No. 4

1.4.7Notebook Expansion Capabilities

Expansion capabilities built into the Extensa notebook series include:

∙User installable expansion RAM memory (to a maximum of 40 MB)

∙By removing the floppy drive, you can add either a second battery pack or CD-ROM Drive.

∙Cable Connect PS/2 Numeric Keypad option, TI Part No. 2581381-0001, or other PS/2 type device (e.g. keyboard or mouse) can be attached to the PS/2 Port.

∙A parallel device can be attached to the notebook’s external 25-pin parallel port (EPP/ECP compatible).

∙With one of the DockMate desktop expansion systems installed, additional expansion ports are available

1-8 General Description

1.5Standard Test Features

The Extensa Series Notebook Computers use modular design and built-in test features to reduce the mean time to repair. A power on self test program automatically verifies the operational state of the primary circuits. Also, the notebook contains a powerful suite of diagnostic tests called PC-Doctor, (described in detail in Appendix B) that can perform additional levels of diagnostic testing.

1.6Notebook Assemblies and Subassemblies

The Extensa Series Notebooks are modular in design and can be disassembled for maintenance purposes using a standard set of flat-bladed, Phillips-head and hexagonal screwdrivers. The major assemblies that comprise a typical notebook in the Extensa family are shown in Figure 1-6 and briefly described in the following paragraphs.
