19
Power Sources
Your computer has two types of power sources: a Lithium-Ion
battery or an AC adapter.
CONNECTING THE POWER ADAPTERS
The AC adapter provides power for operating your notebook PC and
charging the battery.
Connecting the AC Adapter
1. Plug the DC output cable into the DC power jack of your notebook
PC.
2. Plug the AC adapter into an AC electrical outlet.
Switching from AC Adapter Power to Battery
Power
1. Be sure that you have at least one charged battery installed.
2. Remove the AC adapter. Your notebook will automatically switch
from DC power to battery power.
Note: The Lithium-Ion battery is not charged upon purchase. Initially, you
will need to connect the AC adapter to use your notebook PC.
20
RECHARGING THE BATTERY
The Lithium-Ion battery is recharged internally using the AC adapter. To
recharge the battery, make sure the battery is installed and the computer is
connected to the AC adapter. There is no "memory effect" in Lithium-Ion
batteries; therefore, you do not need to discharge the battery completely
before recharging. The charge times will be significantly longer if your
notebook PC is in use while the battery is charging. If you want to charge
the battery more quickly, put your computer into Suspend mode or turn it
off while the adapter is charging the battery.
Low Battery State
When the battery charge is low, a notification message appears. If you do
not respond to the low battery message, the battery continues to discharge
until it is too low to operate. When this happens, your notebook PC goes
into Suspend mode. There is no guarantee your data will be saved once the
notebook reaches this point.
Caution: To protect your notebook from damage, use only the power
adapter that came with it because each power adapter has its own power
output rating.
Once your notebook PC goes into Suspend mode as a result of a
dead battery, you will be unable to resume operation until you provide a
source of power either from an adapter or a charged battery. Once you
have provided power, you can press the Suspend/ Resume button to
resume operation. In Suspend mode, your data is maintained for some
time, but if a power source is not provided promptly, the Power indicator
stops flashing and then goes out, in which case you have lost the data that
was not saved. Once you provide power, you can continue to use your
computer while an adapter charges the battery.
21
Battery Replacement
There is danger of explosion if an incorrect battery type is used for
replacement. For computers equipped with a replaceable lithium-ion battery
pack, the following applies:
• If the battery is placed in an OPERATOR ACCESS AREA, there shall
be a marking close to the battery, or a statement in both the
operating and the servicing instructions;
• If the battery is placed elsewhere in the computer, there shall be a
marking close to the battery or a statement in the servicing
instructions. The marking or statement shall include the following or
similar text:
Caution: Risk of explosion if battery is replaced with an incorrect type.
Dispose of used batteries according to the instructions.
Standby and hibernation
Standby and hibernation are energy-saving features that conserve
power and reduce startup time. They can be initiated by you or by the
system. For more information, refer to "Initiating standby, hibernation or
shutdown."
Standby
CAUTION: To avoid a complete battery discharge, do not leave the
computer in standby for extended periods. Connect the computer to an
external power source.
Standby reduces power to system components that are not in use.
When standby is initiated, your work is stored in random access memory
(RAM), and then the screen is cleared. When the computer is in standby,
22
the power lights blink. When you resume from standby, your work returns
to the screen where you left off.
CAUTION: To reduce the risk of information loss, save your work before
initiating standby.
Hibernation
CAUTION: If the configuration of the computer is changed during
hibernation, resuming from hibernation may not be possible. When the
computer is in hibernation: Do not connect the computer to or disconnect
the computer from an expansion product. Do not add or remove memory
modules. Do not insert or remove any hard drives or optical drives. Do not
connect or disconnect external devices. Do not insert or remove an external
media card, such as a MultiMediaCard.
Hibernation saves your work to a hibernation file on the hard drive,
and then shuts down the computer. The power lights are turned off. When
you restore from hibernation, your work returns to the screen where you
left off. If a power-on password has been set, the password must be
entered to restore from hibernation.
CAUTION: To reduce the risk of information loss, save your work before
initiating hibernation.
You can disable hibernation. However, if hibernation is disabled and
the system reaches a lowbattery condition, the system will not automatically
save your work while power is on or when standby has been initiated.
Initiating standby, hibernation or shutdown
The following sections explain when to initiate standby or
hibernation and when to shut down the computer.
23
NOTE: You cannot initiate any type of networking communications or
perform any computer functions while the computer is in standby or
hibernation.
When you leave your work
When standby is initiated, your work is stored in random access
memory (RAM), and then the screen is cleared. When the computer is in
standby, it uses less power than when it is on. Your work returns instantly
to the screen when you resume from standby. Hibernation saves your work
to a hibernation file on the hard drive, and then shuts down the computer.
When the computer is in hibernation, it uses much less power than
when it is in standby. When the computer will be unused and disconnected
from external power for an extended period, shut down the computer and
remove the battery pack to extend the life of the battery pack. For details
on battery pack storage, refer to "Storing a battery pack."
When a reliable power supply is unavailable
Be sure that hibernation remains enabled, especially if you are
operating the computer on battery power and do not have access to an
external power supply. If the battery pack fails, hibernation saves your work
to a hibernation file and shuts down the computer. It is recommended that
if you pause your work when the power supply is uncertain, you take one of
the following actions:
• Save your work, and then initiate standby.
• Initiate hibernation.
• Shut down the computer.

that allows you to receive instant e-mail notification about product
updates, software drivers, and creative ideas to help you get more
out of the computer.
•Create a backup strategy. A virus or an electrical outage could
damage or destroy your information. Back up your files onto a CD-
RW, DVD+RW, or USB drive to protect the security of your files.
•Create a restore point. In the event of a computer problem,
these benchmarks allow you to go back in time to a point before the
computer encountered a problem.
•Create a PC tune-up schedule. Create weekly and monthly
reminders to back up files, update virus software, and perform
hardware and software maintenance.

Troubleshooting
The computer will not start up.
To turn on the computer, press the power button. When the computer is
turned on, the power light is turned on.
If the computer and the power light are not turned on when you press the
power button, adequate power may not be available to the computer.
The suggested actions below may help you determine the reason the
computer will not start up:
•If the computer is plugged into an AC outlet, verify that the AC
outlet is providing adequate power by plugging another electrical
device into the outlet.
•If the computer is running on battery power or is plugged into an
external power source other than an AC outlet, plug the computer
into an AC outlet using the AC adapter. Make sure the power cord
and AC adapter connections are secure.
•If the computer is running on battery power:
oRemove the primary battery pack and travel battery pack (if
applicable) and plug the computer into an AC outlet using
the AC adapter. If the computer starts up, one of the battery
packs may need to be replaced.
oIf the battery light on the front of the computer is blinking,
the battery pack has reached a low-battery condition, which
may not allow the computer to start up. Plug the computer
into an AC outlet using the AC adapter to start the computer
and allow the battery to charge.

The computer screen is blank.
If you have not turned off the computer but the screen is blank, the
computer may be in standby or hibernation, may not be set to display the
image on the computer screen, or the display switch may not be functioning
properly.
The suggested actions below may help you determine the reason
the computer screen is blank.
• To resume from standby or restore from hibernation, briefly press
the power button.
Standby and hibernation are energy-saving features that can turn
off the display. Standby and hibernation can be initiated by the
system while the computer is in Microsoft® Windows® but is not in
use or has reached a critical low-battery condition. To change these
and other power settings, select Start > Settings > System >
Power and sleep > Additional power settings.
• To transfer the image to the computer screen, press fn+f3. On most
models, when an optional external display device, such as a
monitor, is connected to the computer, the image can be displayed
on the computer screen or the external display, or on both devices
simultaneously. When you press fn+f3 repeatedly, the image
alternates among the computer display, one or more external
display devices, and simultaneous displays on all devices.
• Press the display switch fn+10.
The software is functioning abnormally.
If the software becomes unresponsive or responds abnormally:
• Restart the computer:
o Select Start > Power > Restart. If you cannot restart the
computer using these procedures, refer to the next section,
"The computer is turned on, but is not responding."
38
•Run a virus scan.
•If the computer feels unusually warm, allow it to cool to room
temperature. For more information about computer overheating,
refer to "The computer is extremely warm." later in this chapter.
•If you are using an optional wireless mouse, make sure that the
mouse battery has an adequate charge.
The computer is turned on, but is not
responding.
If the computer is turned on, but is not responding to software
applications or keyboard commands, try first to shut down the computer
through the operating system by selecting Start > Power > Shutdown.
If the computer remains unresponsive, try the emergency shutdown
procedures in the following sequence:
1. If the computer is in Windows, press ctrl+alt+delete. Then, click
Power button located at lower right of the window pane then click
Shutdown.
2. If you cannot shut down the computer by using ctrl+alt+del,
press and hold the power button for at least 5 seconds.
3. If you are unable to shut down the computer by using the power
button, unplug the computer from external power and remove the
battery pack.
The computer is extremely warm.
It is normal for the computer to feel warm to the touch while it is in
use. But if the computer feels extremely warm, it may be overheating
because a vent is blocked. If you suspect that the computer is overheating,
allow the computer to cool to room temperature. Then be sure to keep all
vents free from obstructions while you are using the computer.
39
CAUTION: To prevent overheating, do not obstruct vents. Use the
computer only on a hard, flat surface. Do not allow another hard surface,
such as a printer, or a soft surface, such as a pillow or a thick rug or
clothing, to block airflow.
An external device is not working.
If an external device does not function as expected:
•Turn on the device as instructed in the device user guide. Some
devices, such as monitors and printers, may not be powered by the
computer, and must be turned on before the computer is turned on.
•Verify that:
oAll device connections are secure.
oThe device is receiving electrical power.
oThe device, especially if it is an older one, is compatible with
the operating system. For compatibility information, refer to
the Web site of the device manufacturer.
oThe correct drivers are installed and updated. Drivers may
be available on a CD included with the device or on the Web
site of the device manufacturer.
The computer cannot connect to a wireless
local area network (WLAN).
If the computer cannot connect to a WLAN:
•Verify that the computer is within optimal range of a wireless router
(access point).
•Verify that the wireless light on the computer is turned on.
•Verify that the computer wireless antennae are free from
obstructions.
40
•Verify that the wireless router and broadband modem are working
correctly.
