Toshiba Satellite 4030CDT - Maximizing Battery Life

Mobile Computing
Maximizing battery life
♦ How much you use the hard disk and other drives.
♦ Whether you use any optional devices to which the battery
supplies power.
♦ 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 you need to recharge the battery.
Toshiba has combined these options into three preset power-usage
modes:
♦ Home/Office desk
♦ Portable/Laptop
♦ Always on
To select a power-usage mode:
1 Press Fn and F2 simultaneously to display the power-usage pop
up window.
2 While continuing to press Fn, press F2 until you select the
desired power-usage mode. Then release the Fn key.
You are now in the selected mode. The selected mode will be
shown within a square, with the name of the mode to the right.
Maximizing battery life
A main battery can be recharged many times. Gradually over time
it will lose its ability to hold a charge. To maximize the life of your
main battery:
♦ Don't leave the computer plugged in and unused for more than
a few hours. Overcharging the main battery may shorten its
life.
♦ If you are not going to use the computer for a long period of
time, remove the battery pack.
♦ Alternate between battery packs if you have a spare.
