User's Manual
A ten-key numeric keypad is integrated into the
keyboard. Please refer to the
section in Chapter 5, The Keyboard, for
information on using this feature.
Two levels of password security, supervisor and
user, are available to prevent unauthorized
access to your computer.
A specific hot key function automatically locks the
system providing data security.
A microprocessor in the computer's intelligent
*1 power supply detects the battery's charge,
automatically calculates the remaining battery
capacity and protects electronic components
from abnormal conditions such as a voltage
overload from the AC adaptor. This can be
specified in the Power Options.
This feature lets you configure the computer in
*1
order to save battery power. This can be
specified in the Power Options.
This feature automatically turns power to the
computer off when the display panel is closed,
and turns it back on when the display panel is
opened. This can be specified in the Power
Options.
When battery power is exhausted to the point that
computer operation cannot be continued, the
*1 system automatically enters Hibernation Mode
and shuts itself down. This can be specified in the

*1 To protect against overheating, the processor
has an internal temperature sensor so that, if the
computer's internal temperature rises to a certain
level, the cooling fan is turned on or the
processing speed is lowered. This can be
specified in the Power Options.
This feature uses the acceleration sensor built in
the computer to detect vibration and shocks, and
automatically moves the hard disk drive's
read/write head to a safe position in order to
reduce the risk of damage that could be caused
by head-to-disk contact. Refer to the
Hard Disk Drive (HDD) Protection
Chapter 4, Operating Basics, for more details.
