Maximizing Battery Operating Time - Toshiba Satellite M40 User Manual

Maximizing 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:
• CPU Precessing speed
• Screen brightness
• Cooling Method
• System standby
• System Hibernation
• Monitor Power off
• HDD Power off
❑ How often and how long you use the hard disk, CD/DVD-ROM drive and
the 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 sup-
plies power.
❑ Enabling Resume mode conserves battery power if you are frequently turn-
ing 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.
