Safety warning notice
WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not
place the computer directly on your lap or obstruct the computer air vents. Use the computer only on a
hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft
surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to contact
the skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer and the
AC adapter comply with the user-accessible surface temperature limits defined by the International
Standard for Safety of Information Technology Equipment (IEC 60950).

2 Enhanced Write Filter
Using the Enhanced Write Filter
The Enhanced Write Filter (EWF) provides a secure environment for your computer by protecting it from
undesired flash memory writes. In order to save changes to your system configuration settings, you
must commit your changes in the EWF. Otherwise, the new settings will be lost when the computer is
shut down or restarted.
For additional information on the EWF, see your network administrator.

3 Pointing devices
Using pointing devices
To move the pointer, slide your finger across the TouchPad surface in the direction you want the pointer
to go. Use the TouchPad buttons like the corresponding buttons on an external mouse. To scroll up and
down using the TouchPad vertical scroll zone, slide your finger up or down over the lines.
NOTE: If you are using the TouchPad to move the pointer, you must lift your finger off the TouchPad
before moving it to the scroll zone. Simply sliding your finger from the TouchPad to the scroll zone will
not activate the scrolling function.
Setting pointing device preferences
Use Mouse Properties in Windows to customize settings for pointing devices, such as button
configuration, click speed, and pointer options.
To access Mouse Properties, select Start > Control Panel > Printers and Other Hardware >
Mouse.
Connecting an external mouse
You can connect an external USB mouse to the computer using one of the USB ports on the computer.
A USB mouse can also be connected to the computer using the ports on an optional docking device.
