POWER-UP MODES
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
Resume 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.
CAUTION: 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.
