1. Completely recharge the battery.
2. Use the battery until it is fully discharged
3. Recharge the battery to 100% capacity.
(In this case it doesn’t matter whether or not the computer is being used)
Note: An empty battery will become damaged if stored too long and by following
these steps the battery cycle life and the battery life will increase.
Battery Testing
Testing a battery while its temperature remains high could possibly cause inaccurate mea-
surements, therefore we strongly recommend:
· Waiting 30 minutes before testing a battery that has just been fully charged.
· Waiting at least 30 minutes before recharging a fully discharged battery.
Note: All battery testing should be done on a fully charged or fully discharged battery.
Battery alarm
The battery alarm is activated by a program and will sound when the battery power is low.
Note: If a fully discharged battery has been charged for less than 3 minutes, this program
will not be activated.
This happens when these 3 steps occur:
1. The computer is being used and the low battery alarm sounds.
2. The AC adapter is connected to charge the battery while the computer continues to be
used.
3. The adapter is unplugged within the first 3 minutes of charging.
After this sequence of steps, the computer will eventually shutdown without the low
battery alarm sounding and you will lose any work you have entered and not saved.
Therefore you should make sure that the AC adapter is firmly plugged into the computer
when charging the battery.
