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.

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.
