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:

❖
If you have extra battery packs, rotate their use.
❖
If you will not be using the system for an extended
period, more than one month, remove the battery pack.
❖
Disconnect the AC adapter when the battery is fully
charged. Overcharging makes the battery hot and
shortens its life.
❖
If you are not going to use the computer for more than
eight hours, disconnect the AC adapter.
❖
Store spare battery packs in a cool dry place out of direct
sunlight.
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 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 flashes or
there is some other warning to indicate a low battery,
go to step 4.
Connect the AC adapter to the computer and connect
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.
