Extending battery life
To maximize the life of your battery packs:
■ 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 as detailed below.
■ If you have extra battery packs, rotate their use.
■ If you will not be using the system for an extended period, for example
for more than one month, remove the battery pack from the computer.
■ Store spare battery packs in a cool dry place out of direct sunlight.
1. Turn off the computer's power.
2. Disconnect the AC adaptor and turn on the computer's power - if it
does not turn on then go to Step 4.
3. Operate the computer on battery power for five minutes. If you find
that the battery pack has at least five minutes of operating time,
continue operating until the battery pack is fully discharged,
however, if the Battery indicator flashes or there is some other
warning to indicate a low battery condition, go to Step 4.
4. Connect the AC adaptor to the DC IN 15V jack of the computer,
and to a wall outlet that is supplying power. The DC IN indicator
should glow green, and the Battery indicator should glow orange
to indicate that the battery pack is being charged, however, in the
event that DC IN indicator does not glow this indicates that power
is not being supplied - check the connections for the AC adaptor
and the power cord.
5. Charge the battery pack until the Battery indicator glows green.
