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.

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 adapter and turn on the 
computer’s power. If it does not turn on, go to step 

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 flashes or 
there is some other warning to indicate a low battery, 
go to step 4.

Connect the AC adapter to the computer and the 
power cord/cable to a power outlet. The DC-IN or 
AC power-light should glow green, 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 adapter 
and power cord/cable.

Charge the battery pack until the battery light glows 
green.
