Charging the batteries
When the power in the battery pack becomes low, the
Battery
indicator
flashes orange indicating that only a few minutes of battery power remain.
If you continue to use the computer while the
Battery
indicator flashes, the
computer enables Hibernation mode (so you don’t lose data) and
automatically turns off.
You must recharge a battery pack when it becomes discharged.
Procedures
To recharge a battery pack while it is installed in the computer, connect the
AC adaptor to the
DC IN
socket and plug the other end into a working
outlet.
The
Battery
indicator glows orange when the battery is being charged.
Use only the computer connected to an AC power source or the optional
Toshiba Battery charger to charge the battery pack. Do not attempt to
charge the battery pack with any other charger.
Time
The following table shows the time required to fully charge a discharged
battery.
Charging time (hours)
Battery type Power on Power off
Battery 4 to 10 or longer about 3
RTC battery 10 or longer Doesn't charge
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
Maximizing battery operating time.
The same factors affect charge
time.
