4Connect the AC adapter to the computer and the
power cable to a power outlet.
The DC-IN (if applicable to your system) or AC
power light should glow green, and the battery light
should glow amber to indicate that the battery is
being charged. If the DC-IN or AC power light
indicator does not glow, power is not being supplied.
Check the connections to the AC adapter and power
cable.
5Charge the battery until the battery light glows green.
❖If you have extra batteries, rotate their use.
❖If you will not be using the system for an extended period
(more than one month) remove the battery.
❖Disconnect the AC adapter when the battery is fully
charged. Overcharging makes the battery hot and
shortens life.
❖If you are not going to use the computer for more than
eight hours, disconnect the AC adapter.
❖Store spare batteries in a cool dry place out of direct
sunlight.
Charging batteries
The main battery needs to be charged before you can use it to
power the computer. You can charge the battery using your
computer, or you can use an optional battery charger.
CAUTION: 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 toshiba.com.
