Time
The following table shows the time required to fully charge a discharged
battery.
Charging time (hours)
Battery type Power on Power off
Battery pack 3.5 to 12 or longer about 3.5
RTC battery about 24 about 24 with AC or
Battery pack
The charging time when the computer is on is affected by ambient
temperature, the temperature of the computer and how you use the
computer. If you make heavy use of external devices, for example, the battery
might scarcely charge at all during operation. Refer also to the section
Maximising battery operating time. The same factors affect charge time.
Battery charging notice
The battery may not charge right away under the following conditions:
■ The battery is extremely hot or cold. To make sure the battery charges
to its full capacity, charge the battery at room temperature of 10° to
30°C (50° to 88°F).
■ The battery is nearly completely discharged. Leave the AC adaptor
connected for a few minutes and the battery should begin charging.
Once a battery pack is fully charged, it is recommended that you operate
the computer only on battery power until the battery pack completely
discharges. Doing so extends battery life and helps ensure accurate
monitoring of battery capacity.
The Battery indicator may 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.
■ A cool battery is installed in a warm computer.
In such case, follow the steps below.
1.
Fully discharge the battery by leaving it in the computer with the
power on until the power automatically shuts off.
2. Plug in the AC adaptor.
3. Charge the battery until the Battery indicator glows green.
Repeat these steps two or three times until the battery recovers normal
capacity.
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 recharge the battery.
