Power and Power-Up Modes

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 Battery indicator should glow orange to indicate that the

battery pack is being charged. If the Battery 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 white/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

When the battery pack reaches the end of its operating life you will need to

install a new one. The life of the battery pack is generally about 500

recharges. If the Battery indicator flashes orange shortly after fully

recharging the battery, the battery pack needs to be replaced.
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.

Removing the battery pack

To replace a discharged battery, follow the steps below.

1. Save your work.
2. Turn the computer's power off. Make sure the Power indicator is off.
3. Remove all cables connected to the computer.
4. Turn the computer upside down.
5. Slide and hold the battery release latch to free the battery pack after

moving the battery pack lock into its unlock position - then slide the

battery pack out of the computer.

When handling battery packs, do not short-circuit the terminals. Also do

not drop, hit or otherwise apply impact; do not scratch or break the

casing and do not twist or bend the battery pack.

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 will be lost.

In Hibernation Mode, data will be lost if you remove the battery or

disconnect the AC adaptor before the save is completed. Wait for the

Built-in HDD indicator to go out.

Do not touch the latch while holding the computer. Or you may get

injured by the dropped battery by unintentional release of the latch.
