Power and Power-Up Modes
3. After the battery pack is charged, avoid leaving the AC adaptor
connected and the computer turned off for more than a few hours at a
time. Continuing to charge a fully-charged battery pack can damage the
battery.
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 15V jack and plug the other end into a working
outlet.
The Battery indicator glows orange when the battery is being charged.
Time
The following table shows the approximate time required to fully charge a
discharged battery.
Charging time (hours)
The computer enters Hibernate mode only if Hibernation is enabled in two
places : the Hibernate tab in Power Options and Setup Action tab in
TOSHIBA Power Saver.
Use only the computer connected to an AC power source or the optional
TOSHIBA Battery charger to charge the battery pack. Never attempt to
charge the battery pack with any other charger.
Battery type Power on Power off
High Capacity battery pack (8800mAh) about 10.5 to 21.5 about 4.5
Battery pack (4400mAh) about 5.0 to 11.0 about 2.5
RTC battery 8 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.
