current charge state of the battery. The value displays as a percentage of remaining battery charge.

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.

Conserving battery power

How long a fully charged battery 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 display panel instead of an external monitor❖How much you use the hard disk and other drives

❖Whether you use any optional devices to which the battery supplies power, such as a PC Card

❖Where you are working—since operating time decreases at low temperatures

Toshiba’s power-saving options greatly increase the length of time you can use the computer before it becomes necessary to recharge the battery.

Toshiba has combined these options into preset power usage modes.

You may also set individual power-saving options to suit your own needs. See “Power Management” on page 124 for details.
