Power and Power-up Modes
Charging the batteries
When the power in the battery pack becomes low, the Battery indicator will 
flash amber to indicate that only a few minutes of battery power remain. If 
you continue to use the computer while the Battery indicator flashes, the 
computer will enable Hibernation Mode so that you do not lose any data, 
and automatically turn itself off.
You must recharge a battery pack when it becomes discharged.
Procedures
To recharge a battery pack while it is installed in the computer, connect the 
AC adaptor to the DC IN 19V jack and plug the other end into a working 
outlet - the Battery indicator will glow amber while the battery is being 
charged.
Time
The following table shows the approximate time required to fully charge a 
discharged battery.
Charging time (hours)
Battery charging notice
The battery may not begin charging immediately under the following 
conditions:
■The battery is extremely hot or cold (if the battery is extremely hot, it 
might not charge at all). To ensure the battery charges to its full 
capacity, you should charge it at room temperature of between 5° to 
35°C (41° to 95°F).
■The battery is nearly completely discharged. In this instance you should 
leave the AC adaptor connected for a few minutes and the battery 
should begin charging.
Use only the computer connected to an AC power source to charge the 
battery pack. Never attempt to charge the battery pack with any other 
charger.

Battery Pack (3 cell)about 12 or longerabout 4 or longer
Battery Pack (6 cell)about 12 or longerabout 6 or longer

Battery pack
Please be aware that the charging time when the computer is on is 
affected by ambient temperature, the temperature of the computer and 
how you are using the computer - if you make heavy use of external 
devices for example, the battery might scarcely charge at all during 
operation. Please refer to the section Maximizing battery operating time 
for further information.

Power and Power-up Modes
The Battery indicator may show a rapid decrease in battery operating time 
when you try to charge a battery under the following conditions:
■The battery has not been used for a long time.
■The battery has completely discharged and been left in the computer for 
a long time.
■A cool battery is installed in a warm computer.
In such cases you should follow the steps as detailed below:
1. Fully discharge the battery by leaving it in the computer with the power 
on until the system automatically turns itself off.
2. Connect the AC adaptor to the DC IN 19V jack of the computer, and to 
a wall outlet that is supplying power.
3. Charge the battery until the Battery indicator glows green.
Repeat these steps two or three times until the battery recovers normal 
capacity.
Monitoring battery capacity
Remaining battery power can be monitored in Power Options.
Maximizing battery operating time
A batterys usefulness depends on how long it can supply power on a 
single charge, while how long the charge lasts in a battery depends on:
■Processor speed
■Screen brightness
■System Standby Mode
■System Hibernation Mode
■Display power off period
■Hard disk drive power off period
■How often and for how long you use the hard disk drive, optical disc and 
floppy diskette drives.
■How much charge the battery contained to begin with.
■You should wait at least 16 seconds after turning on the computer 
before trying to monitor the remaining operating time. This is because 
the computer needs this time to check the batterys remaining capacity 
and then calculate the remaining operating time, based on this 
together with the current power consumption.
■Please be aware that the actual remaining operating time may differ 
slightly from the calculated time.
■With repeated discharges and recharges, the batterys capacity will 
gradually decrease. In view of this it will be noted that an often used, 
older battery will not operate for as long as a new battery even when 
both are fully charged.

Power and Power-up Modes
■How you use optional devices, such as a USB device, to which the 
battery supplies power.
■Whether you enable Standby Mode, which can conserve battery power 
if you are frequently turning the computer off and on.
■Where you store your programs and data.
■Whether you close the display panel when you are not using the 
keyboard - closing the display saves power.
■The environmental temperature - operating time decreases at low 
temperatures.
■The condition of the battery terminals - you should always ensure the 
terminals stay clean by wiping them with a clean dry cloth before 
installing the battery pack.
Retaining data with power off
When you turn off your computer with fully charged batteries, the batteries 
retain data for the following approximate time periods.
Retention Time
Extending battery life
To maximize the life of your battery packs:
■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 as detailed below.
1. Turn off the computers power.
2. Disconnect the AC adaptor and turn on the computers power - if it does 
not turn on then go to Step 4.
3. Operate the computer on battery power for five minutes. If you find that 
the battery pack has at least five minutes of operating time, continue 
operating until the battery pack is fully discharged, however, if the 
Battery indicator flashes or there is some other warning to indicate a 
low battery condition, go to Step 4.
4. Connect the AC adaptor to the DC IN 19V jack of the computer, and to 
a wall outlet that is supplying power. The DC IN indicator should glow 
green, and the Battery indicator should glow amber to indicate that the 
battery pack is being charged, however, in the event that DC IN 
indicator does not glow this indicates that power is not being supplied - 
check the connections for the AC adaptor and the 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, for example 
for more than one month, remove the battery pack from the computer.
■Disconnect the AC adaptor when the battery is fully charged - 
overcharging will make the battery hot and can shorten its operating 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.
Replacing the battery pack
Please be aware that the battery pack is classified as a consumable item.
The operating life of the battery pack will gradually reduce through 
repeated charging and discharging, and will need to be replaced when it 
reaches the end of its operating life. In addition to this, you might also 
replace a discharged battery pack with a charged spare when you are 
operating your computer away from an AC power source for an extended 
period of time.
This section explains how to remove and install the battery pack, and 
begins with the removal process which is detailed through the following 
steps.
To remove a discharged battery, follow the steps as detailed below:
1. Save your work.
2. Turn the computers power off - ensure that the Power indicator is off.
3. Remove all cables and peripherals that are connected to the computer.
4. Close the display panel and turn the computer upside down.
5. Slide the battery safety lock towards the release ( ) position to make 
the battery release latch movable.
■Do not remove the battery pack while the computer is in Standby 
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 pack or 
disconnect the AC adaptor before the save is completed. Wait for the 
Hard Disk Drive 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.
