Battery charging notice
The battery might not begin charging immediately under the following
conditions:
The battery is extremely hot or cold (if the battery is extremely hot, it
might not charge at all). To ensure the battery charges to its full
capacity, charge it at room temperature of between 5°C to 35°C (41–
95°F).
The battery is nearly completely discharged. In this instance, leave the
AC adaptor connected for a few minutes and the battery should begin
charging.
The DC IN/Battery indicator might show a rapid decrease in battery
operating time when you try to charge a battery under the following
conditions:
The battery has not been used for a long time.
The battery has completely discharged and been left in the computer
for a long time.
In such cases, do the following:
1. Fully discharge the battery by leaving it in the computer with the power
on until the system automatically turns itself off.
2. Connect the AC adaptor to the DC IN 19 V jack of the computer, and
to a wall outlet that is supplying power.
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.
