Repeat these steps two or three times until the battery pack recovers
normal capacity.
Monitoring battery pack capacity
Remaining battery power can be monitored using the following methods.
When you use the computer with the keyboard dock, the second battery
pack is the first source to provide power.
Maximizing battery operating time
The usefulness of a battery pack depends on how long it can supply power
on a single charge, while how long the charge lasts in a battery pack
depends on:
User's Manual
Clicking the battery icon on the Windows taskbar
Via the Battery Status (average remaining battery power of Battery1
and Battery2) in the Windows Mobility Center window
Wait several seconds to monitor the remaining operating time because
the computer needs time to check the remaining capacity of the
battery pack 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 pack capacity
will gradually decrease. In view of this, it is noted that an often used,
older battery pack will not operate for as long as a new battery pack
even when both are fully charged.
Processor speed
Screen brightness
System Sleep Mode
System Hibernation Mode
Display power off period
How often and for how long you use the internal storage and external
disk drives, for example, optical disc
How much charge the battery pack contained to begin with
How you use optional devices, such as a USB device, to which the
battery pack 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 screen when you are not using the
