❖If a battery is leaking or damaged, replace it immediately.
Use protective gloves when handling a damaged battery.
❖To replace the main battery, use an identical battery that
you can purchase through the Toshiba Web site at
accessories.toshiba.com.
❖A reverse polarity condition should be avoided with all
batteries. The main battery is designed so that it cannot
be installed in reverse polarity.
❖Charge the battery only in the computer or in a battery
charger designated as an approved option.
❖When you install the battery pack, you should hear a
click when it is seated properly.
❖Do not expose the battery pack to fire. The battery pack
could explode.
Maximizing battery life
To maximize the life of your battery pack:
❖At least once a month, disconnect the computer from a
power source and operate it on battery power until the
battery pack fully discharges. Before doing so, follow the
steps below:
1Turn off the computer’s power.
2Disconnect the AC adaptor and turn on the
computer’s power. If it does not turn on, go to step 4.
3Operate the computer on battery power for five
minutes. If the battery pack has at least five minutes
of operating time, continue operating until the battery
pack is fully discharged. If the battery light flashes or
there is some other warning to indicate a low battery,
go to step 4.
4Connect the AC adaptor to the computer and connect
the power cord/cable to a power outlet. The DC-IN or
AC power-light should glow blue, and the battery
light should glow amber to indicate that the battery
pack is being charged. If the DC-IN or AC power-
light indicator does not glow, power is not being
supplied. Check the connections for the AC adaptor
and power cord/cable.
