Power and Power-Up Modes
Maximizing battery operating time
A battery's usefulness depends on how long it can supply power on a
single charge, while how long the charge lasts in a battery depends on:
■ How you configure the computer in relation to its available power saving
options. The computer provides the ability to configure various power
saving settings through the TOSHIBA Power Saver, in order to
conserve battery power. As an overview these settings cover:
■ Processor speed
■ Screen brightness
■ System cooling method
■ System Standby Mode
■ System Hibernation Mode
■ Display power off period
■ Hard disk drive power off period
■ How often and for how long you use the hard disk drive and external
disk(c) drives, for example, optical disc and floppy diskette drive.
■ How much charge the battery contained to begin with.
■ How you use optional devices, such as a PC Cards, to which the
battery supplies power.
■ Whether you enable Standby Mode, which can conserve battery power
if you are frequently turning the computer off and on.
■ Where you store your programs and data.
■ Whether you close the LCD display panel when you are not using the
keyboard - closing the display saves power.
■ The environmental temperature - operating time decreases at low
temperatures.
■ The condition of the battery terminals - you should always ensure the
terminals stay clean by wiping them with a clean dry cloth before
installing the battery pack.
