Introduction
Innovative technology and ergonomic design make this notebook the ideal user-friendly and reliable
travel companion. Your operating system is pre-installed on the hard disk to facilitate the procedure
when you use your notebook for the first time.
The energy-saving processor and the energy-saving functions that can be configured allow you to use
the battery capacity of your notebook effectively. By using an additional battery instead of the disk
drive, you can double the notebook’s mobile operation time.
Your notebook has 32 - 192 MB of main memory installed, depending on the upgrade level. Data is
saved on an Enhanced-IDE hard disk drive. Your notebook is also equipped with a 3 1/2" floppy disk
drive and a CD-ROM drive. In addition, your notebook can be equipped with a DVD drive or with a 2ndd
hard disk drive. Two PC card slots (CardBus or PCMCIA) enable the notebook to operate two type II
PC cards or one type III PC card.
For mouse control the notebook provides a touchpad. A double-touch directly on the touchpad is all
that is needed, for example, to open an application.
Your notebook has connectors for external devices such as, e.g. external monitor, printer and mouse.
The parallel port (which supports ECP and EPP modes) is designed to accommodate bi-directional
data transfer. You can connect peripherals such as, e. g. scanner, loudspeakers, gamepads, keyboard
or mouse via the USB interface.
The notebook disposes of a infrared interface for wireless data transfer.
In addition, the notebook has a connection port for a MobiDock or a QuickPort.
An audio controller, two loudspeakers, a microphone, an audio input and output and a loudspeaker
output provide your notebook with an audio capability. You can thus incorporate voice, noise effects
and music into your notebook environment. You can also connect an external microphone and an
external loudspeaker.
The system settings of the notebook can be configured via the user-friendly BIOS Setup program.
Certain system settings (e.g. screen display, power-management functions) can be modified via
various key combinations while you are using the notebook.
Your notebook has a number of security features to ensure that no unauthorized persons can access
your data. For example, you can activate a screen saver with password protection. The security
functions in the BIOS Setup also allow you to protect your data by means of passwords.
This Operating Manual tells you how to put your notebook into operation and how to operate it in daily
use.
Further information on this notebook is provided:
• in the "Safety Notes" manual which is included with your notebook
• in the documentation of your operating system
• on the SCENIC Mobile CD "Drivers & Utilities"
• in the information files (e. g. *.TXT, *.WRI, *.DOC, *.HLP)
• on the Internet under www.sni-pc.de/drivercd

Unpacking and checking the delivery Preparation for use and operation
A26391-K84-Z100-1-7619 9
Preparation for use and operation
!Pay attention to the chapter "Important notes".
You must charge the battery and install the application programs before you can work with the
notebook. The operating system and required drivers are preinstalled.
When used away from a wall power outlet, the notebook runs on its built-in battery. You can increase
battery life by enabling its power management features.
If you use the notebook in a normal office situation, you run it off the mains with the aid of the power
adapter, or in a MobiDock or QuickPort/QuickPort/Plus.
Refer to the chapter on "System expansions" for instructions on how to connect external devices (e.g.
mouse, printer) to the notebook.
Unpacking and checking the delivery
²²
Unpack all the individual parts.
²²
Check the delivery for damage incurred during transport.
²²
Check whether the delivery agrees with the details in the delivery note.

the drive.
Choosing where to set up your notebook
Select a suitable location for the notebook before setting it up. Bear the following points in mind when
looking for a location.
• We recommend that you place your notebook on a surface with good anti-slip qualities. In view of
the multitude of different finishes and varnishes used on furniture, it is possible that the rubber feet
of the devices will mark the surface they stand on.
• Do not expose the notebook to extreme environmental conditions. Protect it from dust, humidity
and heat.
• Keep other objects 100 mm clear of the notebook and its power adapter to ensure adequate
ventilation. The space between the notebook's feet must be clear. Do not place it on a soft
surface (e.g., a carpet or soft furnishings).
• The power adapter must be at least 200 mm away from the notebook. It must be free-standing
and may not be covered. Do not stand the power adapter on heat-sensitive material.

or defective (for measures, see "Charging, caring for and maintaining the battery").
The arrow shows whether the battery is being charged or drained.
The notebook is connected to an external power source (e.g. via the power
adapter).
The notebook is switched to Suspend to DRAM mode.
The floppy disk in the floppy disk drive is being accessed. You must not remove
the floppy disk when this symbol is visible.

Touchpad and Touchpad Keys
!Make sure that the touchpad does not come into contact with dirt, liquids or grease.
Do not touch the touchpad if your fingers are dirty.
Do not rest heavy objects (e.g., books) on the touchpad or the touchpad buttons.
The touchpad enables you to move the mouse pointer on the screen. If, for example, you move one
finger to the left over the touchpad, the mouse pointer also moves to the left.
A brief tap with the finger on the touchpad has the same effect as clicking with the left mouse button. A
brief "double-tap" with the finger on the touchpad has the same effect as double-clicking with the left
mouse button.
The left and right touchpad buttons have the same functions as the left and right mouse buttons.
iIf you attach and install an external mouse, the touchpad and its buttons are disabled. If you
attach an external serial mouse, you must select the Disabled option for the
PS/2 Pointing Device field in the Main Setup. This also releases interrupt 12, so that you can
use it for other applications.

The battery
The battery supplies your notebook with the necessary power during mobile use. You can increase
battery life by enabling its power management features.
The battery charge is indicated by the battery symbol in the display field (see the section "Indicators
and input devices") When you switch on the notebook, it takes a few seconds before the battery status
is displayed.
The battery will last for roughly 500 charge/discharge cycles.
Charging, caring for and maintaining the battery
The battery can only be charged, when the ambient temperature is between 5°C and 40°C.
The battery charge is indicated by the battery symbol in the display field.
A battery is fully charged in approximately three hours if the notebook is switched on. If the notebook is
switched on, the battery will charge in roughly five to six hours.
You can charge the battery by:
• connecting the notebook to the AC adapter
• connecting the notebook to the power adapter
• connecting the notebook to the car adapter
• connecting the notebook to the MobiDock
• connecting the notebook to the QuickPort
Batteries are to be stored in a charged state of approximately 50% over a long period of time (longer
than two months). If you store the batteries up to two months, the charge status of the batteries must
be approximately 30%. The batteries should be stored in a dry environment in temperatures between
+10°C and +25°C.
iIf you do not use the batteries for longer periods, remove them from the notebook. Never
store the batteries in the unit.
