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 adapter 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 adapter to the computer and the
power cord to a power outlet. The DC-IN or AC
power-light should glow green, and the battery
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.
5Charge the battery pack until the battery glows green.
❖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.
