Step 2: Discharging the Battery Pack
Ä
CAUTION: To prevent loss of information, save your work before 
beginning an unattended discharge procedure.
The computer must remain on throughout the discharge process. 
The battery pack can discharge whether or not you are using the 
computer, but the battery pack will discharge faster if the 
computer is in use.
If you use the computer occasionally during the discharge process 
described below and energy-saving timeouts have been disabled, 
expect the following performance from your system during the 
discharge:
■Any unsaved work from your current session will be lost 
when the battery pack is fully discharged and the computer is 
shut down.
■The system will not turn off a connected optional monitor.
■The system will not decrease hard drive speed while the 
computer is idle.
■System-initiated hibernation will not occur.
To fully discharge the battery pack:
1. Disable hibernation. To disable hibernation:
Select Start > Control Panel > Performance and 
Maintenance
 > Power Options > Hibernate tab. Then clear 
the Enable hibernation check box
.
2. Select Start > Control Panel > Performance and 
Maintenance
 > Power Options > Power Schemes tab.
3. Record all settings in the Plugged in column and all settings 
in the Running on batteries column, so that you can reset 
them after calibration.
4. Use the drop-down lists to set each item in both columns 
to
 Never.
5. Click OK.

6. Disconnect the computer from the external power source, 
but
 do not turn off the computer.
7. Run the computer on battery power until the battery pack is 
fully discharged. The battery light begins to blink when the 
battery pack has discharged to a low-battery condition. When 
the battery pack is fully discharged, the computer is shut 
down.
Step 3: Recharging the Battery Pack
1. Plug the computer into external power until the battery pack 
is fully recharged and the
 battery light is turned off.
You can use the computer while the battery pack is 
recharging, but the battery pack will charge faster if the 
computer is turned off.
2. If the computer is turned off, turn on the computer after 
the
 battery pack is fully charged and the battery light is off.
3. Display the settings on the Power Schemes table. To access 
the
 Power Schemes tab:
Select Start > Control Panel > Performance and 
Maintenance > Power Options > Power Schemes tab.
4. Reenter the settings you recorded earlier for the items in the 
Plugged in column and the Running on batteries column.
5. Click OK.
ÄCAUTION: After calibrating the battery pack, reenable hibernation. 
Failure to reenable hibernation may result in a complete battery 
discharge and potential information loss. To reenable hibernation: 
Select Start > Control Panel > Performance and 
Maintenance
 > Power Options > Hibernate tab. Select the 
Enable hibernation check box, and then click Apply.

Conserving Battery Pack Power
Using the following battery conservation settings and procedures 
extends the time that a battery pack can run the computer from a 
single charge.
Conserving Power as You Work
To conserve power as you work:
■Prevent devices you are not using from drawing power from 
the computer. For example:
❏Turn off wireless and local area network (LAN) 
connections and close modem applications.
❏Disconnect any external devices from the computer that 
are not plugged into an external power source.
❏Stop or remove any optional digital cards that you are not 
using.
❏Turn off a device connected to the S-Video–out jack. 
■Use optional, externally powered speakers instead of the 
internal speakers whenever possible. When you must use 
the
 internal speakers, minimize system volume. Volume can 
be adjusted with the volume buttons.
■Minimize screen brightness. 
❏To decrease screen brightness, press the fn+f7 hotkey. 
❏To increase screen brightness, press the fn+f8 hotkey.
■If you leave your work, initiate standby or hibernation, or 
shut down the computer.

Selecting Power Conservation Settings
You can set and use the following power conservation settings 
only while the computer is in Windows. 
To set the computer to use less power in Windows:
■Select a short wait for the screen saver and select a screen 
saver with minimal graphics and motion. To select a screen 
saver and a screen saver wait time: 
Select Start > Control Panel > Appearance and Themes > 
Display > Screen Saver tab, and then follow the instructions 
on the screen.
■Select or create a power scheme that minimizes power use. 
For more information about using power schemes, refer to the 
“
Using Power Schemes” section earlier in this chapter.
Storing a Battery Pack
ÄCAUTION: To prevent damage to a battery pack, do not expose it to 
high temperatures for extended periods of time.
If the computer will be unused and disconnected from external 
power for more than 2
 weeks, remove and store the battery pack.
High temperatures, which may be present in parked cars or some 
workplaces, accelerate the self-discharge rate of a stored battery 
pack. To prolong the charge of a stored battery pack, place it in a 
location that is cool and dry.
Calibrate a battery pack that has been stored for one month or 
more before using it.

External Audio Devices
Using the Audio-In (Microphone) Jack
A device connected to the microphone jack can be used only 
when the computer is in Windows.
The audio-in jack, identified in the following illustration, 
connects an optional monaural (single sound channel) 
microphone. 
It is recommended that you use an electret condenser microphone 
with a 3.5-mm plug. If you connect a dynamic microphone, the 
recommended sensitivity may not be achieved.

Using the Embedded Microphone 
(Select
 Models Only)
Select computer models include a built-in microphone, located on 
the top of the display. For more information, refer to the “
Camera 
and Microphone (Select Models Only)” section in Chapter 1, 
“Hardware.”
Using the Audio-Out (Headphone) Jacks
ÅWARNING: To reduce the risk of personal injury, adjust the volume 
before putting on headphones.
Ä
CAUTION: To prevent possible damage to an external device, do not 
plug a monaural (single sound channel) plug into an audio-out jack.
Connecting the Audio-Out Jacks
An audio-out jack, sometimes called a headphone jack, connects 
optional headphones or externally powered stereo speakers. An 
audio-out jack is also used to connect the audio functions of 
an
 audio/video device such as a television or VCR. The computer 
is set by default to transmit analog audio signals through the 
audio-out (headphone) jack.
The computer can transmit S/PDIF signals only through an 
optional expansion product.
