Power and Power-Up Modes 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 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. 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. 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. Use only the computer connected to an AC power source to charge the battery pack. Do not attempt to charge the battery pack with any other charger. Time The following table shows the approximate time required to fully charge a discharged battery. Charging time (hours) Battery type Power on Power off Battery pack (6 cell) about 4 or longer about 3 or longer Battery pack (12 cell) about 5 or longer about 4 or longer RTC battery about 14 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.
