Maximising Battery Pack Operating Time; Retaining Data With Power Off; Extending Battery Pack Life - Toshiba Portege 7200CTe User Manual

Maximising battery pack operating time

A battery pack's usefulness depends on how long it can supply power on a
single charge.
How long the charge lasts in a battery pack depends on:
How you configure the computer, for example, whether you enable battery-
power saving options. The computer provides a battery save mode to
conserve battery power. This mode has the following options:
•
•
•
See Chapter 7,
How often and how long you use the hard disk and the diskette drive.
How much charge the battery pack contained to begin with.
How you use optional devices, such as a PC card, to which the battery
pack supplies power.
Enabling Resume (Suspend or Standby) mode conserves battery
power if you are frequently turning the computer off and on.
Enabling Hibernation mode conserves battery power more effectively
than Resume (Suspend or Standby) mode, if you leave the computer
off for longer intervals. Resume mode requires battery power to
maintain data in memory, but Hibernation mode does not. However,
Resume mode is faster and requires less power to startup when you
turn on the computer.
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 pack terminals. Make sure the battery pack
terminals stay clean by wiping them with a clean dry cloth before
installing the battery pack.

Retaining data with power off

battery packs retain data for the following approximate time periods:
