The remaining battery charge is indicated on the top left side
of the dialog box.
With repeated discharges and recharges, the battery’s
capacity will gradually decrease. A frequently used older
battery will not power the computer for as long as a new
battery, even when both are fully charged.
TECHNICAL NOTE: The computer drains the battery faster at
low temperatures. Check your remaining charge frequently if
you are working in temperatures below 50 degrees Fahrenheit.
The computer calculates the remaining battery charge based
on your current rate of power use and other factors such as the
age of the battery.
The Windows ® operating system has additional power
management options that can be accessed through an icon in
the Control Panel. For more information, see
“Power
Management” on page 196 .
Conserving battery power
How long a fully charged battery pack lasts when you are
using the computer depends on a number of factors, such as:
❖ How the computer is configured.
❖ How much you use the hard disk, DVD-ROM or multi-
function drive, and diskette drives, or other optional
devices.
❖ Where you are working, since operating time decreases at
low temperatures.
There are various ways in which you can conserve power and
extend the operating time of your battery:
❖ Enable Standby or Hibernation, which saves power when
you turn off the computer and turn it back on again.
❖ Use Toshiba’s power-saving options.
