Never leave batteries in the battery charger for more than
a week at a time. Doing so may reduce the potential
charge of the battery.
Use only battery chargers designed to work with your
notebook computer. You can order a Toshiba battery
charger from Toshiba’s Web site at
accessories.toshiba.com.
Charging the main battery
To charge the battery, plug the computer into a live wall
outlet. It takes several hours to charge the battery with the
computer off. It takes much longer to charge the battery while
the computer is on.
TECHNICAL NOTE: When your computer is using all of its
power to run applications, features, and devices, the battery
does not charge. Use your computer’s Power Saver utility to
set and maintain a power level that allows the battery to
recharge as needed. For more information, see “Power
Management” on page 159.
The battery may not start charging immediately if:
❖The battery is extremely hot or cold.
To ensure that the battery charges to its full capacity, wait
until it reaches room temperature (50 to 80 degrees
Fahrenheit, 10 to 26 degrees Celsius).
❖The battery is almost completely discharged.
