							Maximizing battery discharge time
Battery discharge time varies depending on the features you use while on battery power. Maximum
discharge time gradually shortens, as the battery storage capacity naturally degrades.
Tips for maximizing battery discharge time:
●Lower the brightness on the display.
●Check the Power saver setting in Power Options.
●Remove the battery from the computer when it is not being used or charged.
●Store the battery in a cool, dry location.
Managing low battery levels
The information in this section describes the alerts and system responses set at the factory. Some low-
battery alerts and system responses can be changed using Power Options in Windows Control Panel.
Preferences set using Power Options do not affect lights.
Identifying low battery levels
When a battery that is the sole power source for the computer reaches a low battery level, the battery
light blinks.
If a low battery level is not resolved, the computer enters a critical battery level, and the battery light
begins blinking rapidly.
The computer takes the following actions for a critical battery level:
●If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates
Hibernation.
●If Hibernation is disabled and the computer is on or in the Sleep state, the computer remains briefly
in the Sleep state, and then shuts down and loses any unsaved information.
Resolving a low battery level
CAUTION:To reduce the risk of losing information when the computer reaches a critical battery level
and has initiated Hibernation, do not restore power until the power lights turn off.
Resolving a low battery level when external power is available
▲Connect one of the following devices:
●AC adapter
●Optional expansion product or docking device
●Optional power adapter
Resolving a low battery level when a charged battery is available
1.Turn off the computer or initiate Hibernation.
2.Remove the discharged battery, and then insert a charged battery.
3.Turn on the computer.

							Calibrating a battery
Calibrate a battery under the following conditions:
●When battery charge displays seem inaccurate
●When you observe a significant change in battery run time
Even if a battery is heavily used, it should not need to be calibrated more than once a month. It is also
not necessary to calibrate a new battery.
Step 1: Fully charge the battery
WARNING!Do not charge the computer battery while you are onboard aircraft.
NOTE:The battery charges whether the computer is off or in use, but it charges faster when the
computer is off.
To fully charge the battery:
1.Insert the battery into the computer.
2.Connect the computer to an AC adapter, optional power adapter, optional expansion product, or
optional docking device, and then plug the adapter or device into external power.

							Step 3: Discharge the battery
The computer must remain on while the battery is being discharged. The battery can discharge whether
or not you are using the computer, but the battery will discharge faster while you are using it.
●If you plan to leave the computer unattended during the discharge, save your information before
beginning the discharge procedure.
●If you use the computer occasionally during the discharge procedure and have set energy-saving
timeouts, expect the following performance from the system during the discharge process:
◦The monitor will not turn off automatically.
◦Hard drive speed will not decrease automatically when the computer is idle.
◦System-initiated Hibernation will not occur.
To discharge a battery:
1.Unplug the computer from its external power source, but do not turn off the computer.
2.Run the computer on battery power until the battery is discharged. The battery light begins to blink
when the battery has discharged to a low battery level. When the battery is discharged, the battery
light turns off and the computer shuts down.
Step 4: Fully recharge the battery
To recharge the battery:
1.Plug the computer into external power and maintain external power until the battery is fully
recharged. When the battery is recharged, the battery light on the computer turns off.
You can use the computer while the battery is recharging, but the battery will charge faster if the
computer is off.
2.If the computer is off, turn it on when the battery is fully charged and the battery light has turned
off.

							Using passwords
A password is a group of characters that you choose to secure your computer information. Several types
of passwords can be set, depending on how you want to control access to your information. Passwords
can be set in Windows or in the non-Windows Setup Utility preinstalled on the computer.
CAUTION:To prevent being locked out of the computer, record each password you set. Because
most passwords are not displayed as they are set, changed, or deleted, it is essential to record each
password immediately and store it in a secure place.
You can use the same password for a Setup Utility feature and for a Windows security feature. You can
also use the same password for more than one Setup Utility feature.
Use the following guidelines when setting a password in Setup Utility:
●A password can be any combination of up to 8 letters and numbers and is case sensitive.
●A password set in Setup Utility must be entered at a Setup Utility prompt. A password set
in Windows must be entered at a Windows prompt.
Use the following tips for creating and saving passwords:
●When creating passwords, follow requirements set by the program.
●Write down your passwords and store them in a secure place away from the computer.
●Do not store passwords in a file on the computer.
●Do not use your name or other personal information that could be easily discovered by an outsider.
The following sections list Windows and Setup Utility passwords and describe their functions. For
additional information about Windows passwords, such as screen-saver passwords, select Start > Help
