Extending battery lifeTo maximize the life of your battery pack:

■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 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 go to step 4.

3.Operate the computer on battery power for five minutes. If the battery pack has at least five minutes of operating time, continue operating until the battery pack is fully discharged. If the Battery indicator flashes or there is some other warning to indicate a low battery, go to step 4.

4.Connect the AC adaptor to the computer and the power cord to a power outlet. The DC IN indicator should glow green, and the Battery indicator should glow orange to indicate that the battery pack is being charged. If the DC IN indicator does not glow, power is not being supplied. Check the connections for the AC adaptor and 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, more than one month, remove the battery pack.

■Store spare battery packs in a cool dry place out of direct sunlight.

Replacing the battery pack

The battery pack is classified as a consumable item.

The operating life of the battery pack will gradually reduce through repeated charging and discharging. It will need to be replaced when it reaches the end of its operating life.

You might also replace a discharged battery pack with a charged spare when you are operating your computer away from an AC power source. This section explains how to remove and install the battery pack.

To remove a discharged battery pack, follow the steps below.■Do not remove the battery pack while the computer is in Sleep Mode.Data is stored in RAM, so if the computer loses power it could be lost.

■In Hibernation Mode, data will be lost if you remove the battery pack or disconnect the AC adaptor before the save is completed. Wait for the HDD indicator to go out.

■Do not touch the battery release latch while holding the computer or the battery pack might fall out due to the unintentional release of the battery release latch and cause injuries.
