Charging the batteries
When the power in the battery pack becomes low, the Battery indicator flashes
amber indicating that only a few minutes of battery power remain. If you con-
tinue 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 amber when the battery is being charged.
Time
The following table shows the approximate time required to fully charge a dis-
charged battery.
Charging time (hours)
Battery type System on System off
Battery pack (3 cell) 8 hours or more 2 hours
Battery pack (6 cell) 8 hours or more 3 hours
Battery pack (9 cell) 8 hours or more 4 hours
RTC battery 24 hours 24 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 Batteries charger to charge the battery pack.
Never attempt to charge the battery pack with any other charger.
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.
