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.
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 19V jack of the computer, and
to a wall outlet that is supplying power. The Power indicator should
glow white, and the Battery
indicator should glow amber to indicate
that the battery pack is being charged, however, in the event that
Power indicator does not glow this indicates that power is not being
supplied - check the connections for the AC adaptor and the power
cord.
