							A Traveling with the computer
For best results, follow these traveling and shipping tips:
●Prepare the computer for traveling or shipping:
◦Back up your information.
◦Remove all discs and all external media cards, such as memory cards.
CAUTION:To reduce the risk of damage to the computer, damage to a drive, or loss of
information, remove the media from a drive before removing the drive from a drive bay and
before shipping, storing, or traveling with a drive.
◦Turn off and then disconnect all external devices.
◦Shut down the computer.
●Take along a backup of your information. Keep the backup separate on the computer.
●When traveling by air, carry the computer as hand luggage; do not check it in with the rest of
your bags.
CAUTION:Avoid exposing a drive to magnetic fields. Security devices with magnetic fields
include airport walk-through devices and security wands. Airport conveyer belts and similar
security devices that check carry-on baggage use X-rays instead of magnetism and do not
damage drives.
●In-flight computer use is at the discretion of the airline. If you plan to use the computer during a
flight, check with the airline in advance.
●If the computer will be unused and disconnected from external power for more than 2 weeks,
remove the battery and store it separately.
●If you are shipping the computer or a drive, use suitable protective packaging and label the
package “FRAGILE.”
●If the computer has a wireless device, a Global System for Mobile Communications (GSM)
device, or a General Packet Radio Service (GPRS) device, the use of these devices may be
restricted in some environments. Such restrictions may apply aboard aircraft, in hospitals, near
explosives, and in hazardous locations. If you are uncertain of the policy that applies to the use
of a particular device, ask for authorization to use it before you turn it on.
●If you are traveling internationally, follow these suggestions:
◦Check the computer-related customs regulations for each country or region on your
itinerary.
◦Check the power cord and adapter requirements for each location in which you plan to use
the computer. Voltage, frequency, and plug configurations vary.
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not
attempt to power the computer with a voltage converter kit sold for appliances.

Resolving issues
The following sections describe several common issues and solutions.
The computer is unable to start up
If the computer does not turn on when you press the power button, the following suggestions may
help you determine why the computer does not start up:
●If the computer is plugged into an AC outlet, plug another electrical device into the outlet to be
sure that the outlet is providing adequate power.
NOTE:Use only the AC adapter provided with the computer or one approved by HP for this
computer.
●If the computer is plugged into an external power source other than an AC outlet, plug the
computer into an AC outlet using the AC adapter. Be sure that the power cord and AC adapter
connections are secure.
The computer screen is blank
If the screen is blank but you have not turned off the computer, one or more of these settings may be
the cause:
●The computer may be in the Sleep state. To exit Sleep, briefly press the power button. Sleep is
an energy-saving feature that turns off the display. Sleep can be initiated by the system while the
computer is on but is not in use, or when the computer has reached a low battery level. To
84 Appendix B   Troubleshooting 
						

							change these and other power settings, right-click the Battery icon on the Windows desktop in
the notification area, at the far right of the taskbar, and then click Preferences.
●The computer may not be set to display the image on the computer screen. To transfer the
image to the computer screen, press fn+f4. On most models, when an optional external display,
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+f4
repeatedly, the image alternates among the computer display, one or more external displays,
and simultaneous display on all devices.
Software is functioning abnormally
If the software is unresponsive or responds abnormally, restart the computer by pointing to the right
side of the screen. When the charms display, click Settings. Click the Power icon, and then click Shut
down. If you cannot restart the computer using this procedure, see the next section, 
The computer is
on but not responding on page 85.
The computer is on but not responding
If the computer is turned on but is not responding to software or keyboard commands, try the
following emergency shutdown procedures, in the sequence provided, until shutdown occurs:
CAUTION:Emergency shutdown procedures result in the loss of unsaved information.
●Press and hold the power button for at least 5 seconds.
●Disconnect the computer from external power and remove the battery.
The computer is unusually warm
It is normal for the computer to feel warm to the touch while it is in use. But if the computer feels
unusually 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. Be
sure to keep all vents free from obstructions while you are using the computer.
WARNING!To reduce the possibility of heat-related injuries or of overheating the computer, do not
place the computer directly on your lap or obstruct the computer air vents. Use the computer only on
a hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft
surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to
contact the skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer
and the AC adapter comply with the user-accessible surface temperature limits defined by the
International Standard for Safety of Information Technology Equipment (IEC 60950).
NOTE:The fan in the computer starts up automatically to cool internal components and prevent
overheating. It is normal for the internal fan to cycle on and off during operation.
An external device is not working

							C Electrostatic discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for
example, the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components. To prevent damage to the computer, damage to a drive, or loss of information, observe
these precautions:
●If removal or installation instructions direct you to unplug the computer, unplug it after being
properly grounded and before removing a cover.
●Keep components in their electrostatic-safe containers until you are ready to install them.
●Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
●Use nonmagnetic tools.
●Before handling components, discharge static electricity by touching an unpainted metal surface
of the component.
●If you remove a component, place it in an electrostatic-safe container.
If you need more information about static electricity or assistance with component removal or
installation, contact HP support.
