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.
How long the charge lasts in a battery depends on:
■ How you configure the computer (for example, whether you enable
battery-power saving options). The computer provides a battery save
mode, which can be set in TOSHIBA Power Saver, to conserve battery
power. This mode has the following options:
■ CPU Processing speed
■ Screen brightness
■ Cooling Method
■ System standby
■ System Hibernation
■ Monitor Power off
■ HDD Power off
■ How often and how long you use the hard disk, optical disc and the
floppy disk drive.
■ How much charge the battery contained to begin with.
■ How you use optional devices, such as a PC card, to which the battery
supplies power.
■ Enabling Standby Mode conserves battery power if you are frequently
turning the computer off and on.
■ Where you store your programs and data.
■ Closing the LCD display panel when you are not using the keyboard
saves power.
■ Operating time decreases at low temperatures.
■ The condition of the battery terminals. Make sure the battery terminals
stay clean by wiping them with a clean dry cloth before installing the
battery pack.
