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 Battery indicator should
glow amber to indicate that the battery pack is being charged,
however, in the event that Battery 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 white.
