Introduction
Low battery
automatic
hibernation
When battery power is exhausted to the point that
computer operation cannot be continued, the
system automatically enters Hibernation and
shuts down. You can specify the setting in the
Setup Action tab in TOSHIBA Power Saver.
Heat dispersal To protect from overheating, the CPU has an
internal temperature sensor. If the computer’s
internal temperature rises to a certain level, the
cooling fan is turned on or the processing speed
is lowered. Use the Cooling Method item of the
Basic Setup tab in TOSHIBA Power Saver.
■ Maximum
Performance

necessary lowers CPU
processing speed.
■ Performance Uses a combination of
fan and lowering the
CPU processing speed.
■ Battery optimized Lowers the CPU
processing speed first,
then if necessary turns

Hibernation This feature lets you turn off the power without
exiting from your software. The contents of main
memory are saved to the hard disk, when you
turn on the power again, you can continue
working right where you left off. Refer to the
Turning off the power section in Chapter 3,
Getting Started, for details.
Standby If you have to interrupt your work, you can turn off
the power without exiting from your software.
Data is maintained in the computer’s main
memory. When you turn on the power again, you
can continue working right where you left off.
TOSHIBA RAID RAID (Redundant Array of Independent Disks)
realizes high performance (striping = RAID0) or
fault tolerance (mirroring = RAID1), which is
configured by arraying multiple independent hard
disk drives.
