■ Clicking the battery icon on the Taskbar
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 Power Options, to conserve battery power.
This mode has the following options:
■ CPU Precessing speed
■ Screen brightness
■ Cooling Method
■ System sleep
■ System hibernation
■ Monitor Power off
■ HDD Power off
■ How often and how long you use the hard disk, optical disc drive and
the diskette drive.
■ How much charge the battery contained to begin with.
■ How you use optional devices, such as an external monitor, to which
the battery supplies power.
■ Enabling hibernation and Sleep Mode conserves battery power if you
are frequently turning the computer off and on.
■ Where you store your programs and data.
Leaving the AC adaptor connected will shorten battery life. At least once a
month, run the computer on battery power until the battery is fully
discharged, then recharged the battery.
■ You should wait at least 16 seconds after turning on the computer
before trying to monitor the remaining operating time. This is because
the computer needs this time to check the battery's remaining capacity
and then calculate the remaining operating time, based on this together
with the current power consumption.
■ Please be aware that the actual remaining operating time may differ
slightly from the calculated time.
■ With repeated discharges and recharges, the battery's capacity will
gradually decrease. In view of this it will be noted that an often used,
older battery will not operate for as long as a new battery even when
both are fully charged.
