Maximising Battery Operating Time; Retaining Data With Power Off - Toshiba Equium A60-199 User Manual

Maximising 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:
■
■
■
■
■
■
■
■
How often and how long you use the hard disk, optical disk drive and
the optional diskette 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 Resume mode conserves battery power if you are frequently
turning the computer off and on.
■
Where you store your programs and data.
■
Closing the display 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.
