Taking care of your battery
❖
Reverse Polarity should be avoided with all batteries. The
main battery is designed so that it cannot be installed in
reverse polarity.
❖
Charge the battery pack only in the computer.
❖
When you install the battery pack, you should hear a
click when it is inserted 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:

Turn off the computer's power.
Disconnect the AC adaptor and turn on the
computer's power. If it does not turn on, go to step 4.
Operate 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 LED
flashes or there is some other warning to indicate a
low battery, go to step 4.
Connect the AC adaptor to the computer and the
power cord to a power outlet. The DC-IN or AC
power-light LED should glow green, and the Battery
LED 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.
Charge the battery pack until the Battery LED glows
green.
