Maximizing Battery Operating Time

A battery's usefulness depends on how long it can provide 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 T2150CD series computers provide a battery save mode to
conserve battery power. This mode has the following four options:
CPU sleep mode
Display auto off
HDD auto off
LCD Brightness
See Chapter 11, Setup and Password
How often and how long you use the hard disk, CD-ROM and the 3 1/2" external
diskette drive.
How much charge the battery contained to begin with.
How you use optional devices, such as the card modem, to which the battery supplies
power.
Enabling AutoResume conserves battery power if you are frequently turning the
computer off and on.
Where you store your programs and data. (It takes less power to access data in a
RAMDRIVE, for example, than on a diskette or the hard disk.)
F Full.
E Empty.
N/A The battery is not installed or cannot be accessed by
the computer.
??? The remaining charge of the battery pack cannot be
determined because the battery pack has been
removed or replaced. In this case the TSETUP or
MaxTime program, described in Chapter 11, Setup
and Password Securtiy, can be used to manually
set the battery capacity.
