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 DC IN indicator should 
glow green, and the Battery indicator should glow amber 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.
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.
