Safety Information
❑ If you are not using your computer for a long period of time, remove the battery pack from the computer to prevent damage
to the battery pack.
❑ If you have not used the battery pack for a considerable amount of time, the remaining battery life may become short.
However, this is normal and does not indicate a malfunction, because the battery pack will gradually discharge over time
even while not in use. Connect the AC adapter to your computer and recharge the battery pack before using the computer
again.
