❖ When you install the battery, you should hear a click when it is seated
properly.
❖ Do not expose the battery to fire. The battery could explode.
Maximizing battery life
A main battery can be recharged many times. Battery life and charge time
vary depending on the applications, power management settings and
features used. To maximize the life of your battery:
❖ At least once a month, disconnect the computer from a power source
and operate it on battery power until the battery fully discharges.
Before doing so, follow the steps below:
1 Turn off the computer’s power.
2 Disconnect the AC adapter and turn on the computer’s power. If
it does not turn on, go to step 4.
3 Operate the computer on battery power for five minutes. If the
battery has at least five minutes of operating time, continue
operating until the battery is fully discharged. If the battery light
flashes or there is some other warning to indicate a low battery,
go to step 4.
4 Connect 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.
5 Charge 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.
