Security features include hardware and software locks — a security 
notch and passwords.

such as a table or handle of a locked drawer. Insert the lock into the 
notch and turn the key to secure the lock. Some keyless models are 
also available.
Using passwords
Passwords protect your computer from unauthorized access. Setting 
these passwords creates several different levels of protection for your 
computer and data:
• Supervisor Password prevents unauthorized entry into the BIOS 
utility. Once set, you must enter this password to gain access to the 
BIOS utility. See Setting passwords on page 41.
• User Password secures your computer against unauthorized use. 
Combine the use of this password with password checkpoints on 
boot-up and resume from Hibernation (if available) for maximum 
security.
• Password on Boot secures your computer against unauthorized 
use. Combine the use of this password with password checkpoints 
on boot-up and resume from Hibernation (if available) for maximum 
security.
Important
Do not forget your Supervisor Password! If you forget your password, 
please get in touch with your dealer or an authorized service center.

POWER MANAGEMENT
This computer has a built-in power management unit that monitors 
system activity. System activity refers to any activity involving one or 
more of the following devices: keyboard, mouse, hard disk, 
peripherals connected to the computer, and video memory. If no 
activity is detected for a period of time, the computer stops some or all 
of these devices in order to conserve energy.

environmental impact, turn off Fast startup:
1. Open the desktop.
2. Click Power Options in the Notification area.
3. Select More Power Options.

							46 - Battery pack
BATTERY PACK
The computer uses a Lithium battery that gives you long use between 
charges.
Battery characteristics
The battery is recharged whenever you connect the computer to the 
AC adapter. Your computer supports charge-in-use, enabling you to 
recharge the battery while you continue to operate the computer. 
However, recharging with the computer turned off significantly 
reduces charge time.
The battery will come in handy when you travel or during a power 
failure. It is advisable to have an extra fully charged battery available 
as backup. Contact your dealer for details on ordering a spare battery.
Charging the battery
To charge the battery, first make sure that it is correctly installed in the 
battery bay. Plug the AC adapter into the computer, and connect to a 
mains power outlet. You can continue to operate your computer on 
AC power while your battery is charging. However, charging the 
battery with the computer turned off significantly reduces charge time.
Conditioning a new battery pack
Before you use a battery pack for the first time, there is a conditioning 
process that you should follow:
1. Insert the new battery without turning the computer on.
2. Connect the AC adapter and fully charge the battery.
3. Disconnect the AC adapter.
4. Turn on the computer and operate using battery power.
5. Deplete the battery until the battery-low warning appears.
Note
You are advised to charge the battery before retiring for the day. Charging 
the battery overnight before traveling enables you to start the next day with a 
fully charged battery.

6. Reconnect the AC adapter and fully charge the battery again.
Follow these steps again until the battery has been charged and 
discharged three times.
Use this conditioning process for all new batteries, or if a battery 
hasnt been used for a long time. If the computer is to be stored for 
more than two weeks, you are advised to remove the battery pack 
from the unit.
The battery conditioning process ensures your battery accepts the 
maximum possible charge. Failure to follow this procedure will prevent 
you from obtaining the maximum battery charge, and will also shorten 
the effective lifespan of the battery.
In addition, the useful lifespan of the battery is adversely affected by 
the following usage patterns:
• Using the computer on constant AC power with the battery inserted. 
If you want to use constant AC power, you are advised to remove 
the battery pack after it is fully charged.
• Not discharging and recharging the battery to its extremes, as 
described above.
• Frequent use; the more you use the battery, the faster it will reach 
the end of its effective life. A standard computer battery has a life 
span of about 300 charges.
Optimizing battery life
Optimizing battery life helps you get the most out of battery operation, 
prolonging the charge/recharge cycle and improving recharging 
efficiency. You are advised to follow the suggestions set out below:
• Purchase an extra battery pack.
• Use AC power whenever possible, reserving battery for mobile use.
• Remove accessories that are not being used (e.g. a USB disk 
drive), as they can continue to draw power.
Warning
Do not expose battery packs to temperatures below 0° C (32° F) or 
above 45° C (113° F). Extreme temperatures may adversely affect the 
battery pack. 
						

							48 - Battery pack
• Store the battery pack in a cool, dry place. The recommended 
temperature is 10° C (50° F) to 30° C (86° F). Higher temperatures 
cause the battery to self-discharge faster.
• Excessive recharging decreases the battery life.
• Look after your AC adapter and battery. 
Checking the battery level
The power meter indicates the current battery level. Rest the cursor 
over the battery/power icon on the taskbar to see the batterys present 
charge level.
Battery-low warning
When using battery power pay attention to the power meter.
When the battery-low warning appears, the recommended course of 
action depends on your situation:
Important
Connect the AC adapter as soon as possible after the battery-low 
warning appears. Data may be lost if the battery is allowed to become 
fully depleted and the computer shuts down.
SituationRecommended Action
The AC adapter 
and a power 
outlet are 
available.1. Plug the AC adapter into the computer, and 
then connect to the main power supply.
2. Save all necessary files.
3. Resume work. 
Turn off the computer if you want to recharge 
the battery rapidly.

charged battery 
pack is available.1. Save all necessary files.
2. Close all applications.
3. Turn off the computer.
4. Replace the battery pack.
5. Turn on the computer and resume work.
