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

Use only the computer connected to an AC power source or the optional 
TOSHIBA Battery charger to charge the battery pack. Never attempt to

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
