Remaining battery power can be monitored using the following methods.
■Clicking the battery icon on the task bar
■Via the Battery Status in the Windows Mobility Center Window
■ 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.
■The actual remaining operation time may differ slightly from the calculated time.
With repeated discharges and recharges, the battery’s capacity will gradually decrease. Even when an
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 such as whether you enable battery power saving options. The computer provides a battery save mode to conserve battery power. This mode has the following options:
■Display auto off
■Hard Disk Drive auto off

■How much charge the battery contained to begin with.
■How you use optional devices, such as a PC Card, to which the battery supplies power.
■Enabling Sleep Mode or Hibernation Mode conserves battery power if you are frequently turning 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.
