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 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.
■ 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.
■ 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.
