3.
Charge the battery until the
DC IN/Battery
indicator glows white.
Repeat these steps two or three times until the battery recovers normal
capacity.
Monitoring battery capacity
Remaining battery power can be monitored using the following methods.
Clicking the battery icon on the Windows Taskbar
Via the Battery Status in the Windows Mobility Center window
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 remaining capacity of the battery and
then calculate the remaining operating time, based on this together
with the current power consumption.
Be aware that the actual remaining operating time might differ slightly
from the calculated time.
With repeated discharges and recharges, the battery capacity will
gradually decrease. In view of this, it is noted that an often used, older
battery will not operate for as long as a new battery even when both
are fully charged.
Maximizing battery operating time
The usefulness of a battery depends on how long it can supply power on a
single charge, while how long the charge lasts in a battery depends on:
Processor speed
Screen brightness
System Sleep Mode
System Hibernation Mode
Display power off period
Hard Disk Drive power off period
How often and for how long you use the Hard Disk Drive and external
disk drives, for example, optical disc
How much charge the battery contained to begin with
How you use optional devices, such as a USB device, to which the
battery supplies power
Whether you enable Sleep Mode, which can conserve battery power if
you are frequently turning the computer off and on
Where you store your programs and data
Whether you close the display panel when you are not using the
keyboard - closing the display saves power.
The environmental temperature - operating time decreases at low
temperatures.
Whether you enable Sleep and Charge function
