Disposing of used batteries

3Operate 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 light flashes or there is some other warning to indicate a low battery, go to step 4.

4Connect the AC adaptor to the computer and the power cord/cable to a power outlet. The DC-IN or AC power-light should glow blue, and the battery light should glow amber to indicate that the battery pack is being charged. If the DC-IN or AC power- light indicator does not glow, power is not being supplied. Check the connections for the AC adaptor and power cord/cable.

5Charge the battery pack until the battery light glows blue.

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.

Disconnect the AC adaptor when the battery is fully charged. Overcharging makes the battery hot and shortens its life.

If you are not going to use the computer for more than eight hours, disconnect the AC adaptor.

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

Disposing of used batteries

The life of a battery pack depends on usage. When the battery pack needs replacing, the main battery light flashes amber shortly after you have fully recharged the battery.

You must discard a battery if it becomes damaged.
